# Azure Logic Apps and Power Automate Instructions

## Overview

These instructions will guide you in writing high-quality Azure Logic Apps and Microsoft Power Automate workflow definitions using the JSON-based Workflow Definition Language (WDL). Azure Logic Apps is a cloud-based integration platform as a service (iPaaS) that provides 1,400+ connectors to simplify integration across services and protocols. Follow these guidelines to create robust, efficient, and maintainable cloud workflow automation solutions.

## Workflow Definition Language Structure

When working with Logic Apps or Power Automate flow JSON files, ensure your workflow follows this standard structure:

```json
{
  "definition": {
    "$schema": "https://schema.management.azure.com/providers/Microsoft.Logic/schemas/2016-06-01/workflowdefinition.json#",
    "actions": { },
    "contentVersion": "1.0.0.0",
    "outputs": { },
    "parameters": { },
    "staticResults": { },
    "triggers": { }
  },
  "parameters": { }
}
```

## Best Practices for Azure Logic Apps and Power Automate Development

### 1. Triggers

- **Use appropriate trigger types** based on your scenario:
  - **Request trigger**: For synchronous API-like workflows
  - **Recurrence trigger**: For scheduled operations
  - **Event-based triggers**: For reactive patterns (Service Bus, Event Grid, etc.)
- **Configure proper trigger settings**:
  - Set reasonable timeout periods
  - Use pagination settings for high-volume data sources
  - Implement proper authentication

```json
"triggers": {
  "manual": {
    "type": "Request",
    "kind": "Http",
    "inputs": {
      "schema": {
        "type": "object",
        "properties": {
          "requestParameter": {
            "type": "string"
          }
        }
      }
    }
  }
}
```

### 2. Actions

- **Name actions descriptively** to indicate their purpose
- **Organize complex workflows** using scopes for logical grouping
- **Use proper action types** for different operations:
  - HTTP actions for API calls
  - Connector actions for built-in integrations
  - Data operation actions for transformations

```json
"actions": {
  "Get_Customer_Data": {
    "type": "Http",
    "inputs": {
      "method": "GET",
      "uri": "https://api.example.com/customers/@{triggerBody()?['customerId']}",
      "headers": {
        "Content-Type": "application/json"
      }
    },
    "runAfter": {}
  }
}
```

### 3. Error Handling and Reliability

- **Implement robust error handling**:
  - Use "runAfter" configurations to handle failures
  - Configure retry policies for transient errors
  - Use scopes with "runAfter" conditions for error branches
- **Implement fallback mechanisms** for critical operations
- **Add timeouts** for external service calls
- **Use runAfter conditions** for complex error handling scenarios

```json
"actions": {
  "HTTP_Action": {
    "type": "Http",
    "inputs": { },
    "retryPolicy": {
      "type": "fixed",
      "count": 3,
      "interval": "PT20S",
      "minimumInterval": "PT5S",
      "maximumInterval": "PT1H"
    }
  },
  "Handle_Success": {
    "type": "Scope",
    "actions": { },
    "runAfter": {
      "HTTP_Action": ["Succeeded"]
    }
  },
  "Handle_Failure": {
    "type": "Scope",
    "actions": {
      "Log_Error": {
        "type": "ApiConnection",
        "inputs": {
          "host": {
            "connection": {
              "name": "@parameters('$connections')['loganalytics']['connectionId']"
            }
          },
          "method": "post",
          "body": {
            "LogType": "WorkflowError",
            "ErrorDetails": "@{actions('HTTP_Action').outputs.body}",
            "StatusCode": "@{actions('HTTP_Action').outputs.statusCode}"
          }
        }
      },
      "Send_Notification": {
        "type": "ApiConnection",
        "inputs": {
          "host": {
            "connection": {
              "name": "@parameters('$connections')['office365']['connectionId']"
            }
          },
          "method": "post",
          "path": "/v2/Mail",
          "body": {
            "To": "support@contoso.com",
            "Subject": "Workflow Error - HTTP Call Failed",
            "Body": "<p>The HTTP call failed with status code: @{actions('HTTP_Action').outputs.statusCode}</p>"
          }
        },
        "runAfter": {
          "Log_Error": ["Succeeded"]
        }
      }
    },
    "runAfter": {
      "HTTP_Action": ["Failed", "TimedOut"]
    }
  }
}
```

### 4. Expressions and Functions

- **Use built-in expression functions** to transform data
- **Keep expressions concise and readable**
- **Document complex expressions** with comments

Common expression patterns:
- String manipulation: `concat()`, `replace()`, `substring()`
- Collection operations: `filter()`, `map()`, `select()`
- Conditional logic: `if()`, `and()`, `or()`, `equals()`
- Date/time manipulation: `formatDateTime()`, `addDays()`
- JSON handling: `json()`, `array()`, `createArray()`

```json
"Set_Variable": {
  "type": "SetVariable",
  "inputs": {
    "name": "formattedData",
    "value": "@{map(body('Parse_JSON'), item => {
      return {
        id: item.id,
        name: toUpper(item.name),
        date: formatDateTime(item.timestamp, 'yyyy-MM-dd')
      }
    })}"
  }
}
```

#### Using Expressions in Power Automate Conditions

Power Automate supports advanced expressions in conditions to check multiple values. When working with complex logical conditions, use the following pattern:

- For comparing a single value: Use the basic condition designer interface
- For multiple conditions: Use advanced expressions in advanced mode

Common logical expression functions for conditions in Power Automate:

| Expression | Description | Example |
|------------|-------------|---------|
| `and` | Returns true if both arguments are true | `@and(equals(item()?['Status'], 'completed'), equals(item()?['Assigned'], 'John'))` |
| `or` | Returns true if either argument is true | `@or(equals(item()?['Status'], 'completed'), equals(item()?['Status'], 'unnecessary'))` |
| `equals` | Checks if values are equal | `@equals(item()?['Status'], 'blocked')` |
| `greater` | Checks if first value is greater than second | `@greater(item()?['Due'], item()?['Paid'])` |
| `less` | Checks if first value is less than second | `@less(item()?['dueDate'], addDays(utcNow(),1))` |
| `empty` | Checks if object, array or string is empty | `@empty(item()?['Status'])` |
| `not` | Returns opposite of a boolean value | `@not(contains(item()?['Status'], 'Failed'))` |

Example: Check if a status is "completed" OR "unnecessary":
```
@or(equals(item()?['Status'], 'completed'), equals(item()?['Status'], 'unnecessary'))
```

Example: Check if status is "blocked" AND assigned to specific person:
```
@and(equals(item()?['Status'], 'blocked'), equals(item()?['Assigned'], 'John Wonder'))
```

Example: Check if a payment is overdue AND incomplete:
```
@and(greater(item()?['Due'], item()?['Paid']), less(item()?['dueDate'], utcNow()))
```

**Note:** In Power Automate, when accessing dynamic values from previous steps in expressions, use the syntax `item()?['PropertyName']` to safely access properties in a collection.

### 5. Parameters and Variables

- **Parameterize your workflows** for reusability across environments
- **Use variables for temporary values** within a workflow
- **Define clear parameter schemas** with default values and descriptions

```json
"parameters": {
  "apiEndpoint": {
    "type": "string",
    "defaultValue": "https://api.dev.example.com",
    "metadata": {
      "description": "The base URL for the API endpoint"
    }
  }
},
"variables": {
  "requestId": "@{guid()}",
  "processedItems": []
}
```

### 6. Control Flow

- **Use conditions** for branching logic
- **Implement parallel branches** for independent operations
- **Use foreach loops** with reasonable batch sizes for collections
- **Apply until loops** with proper exit conditions

```json
"Process_Items": {
  "type": "Foreach",
  "foreach": "@body('Get_Items')",
  "actions": {
    "Process_Single_Item": {
      "type": "Scope",
      "actions": { }
    }
  },
  "runAfter": {
    "Get_Items": ["Succeeded"]
  },
  "runtimeConfiguration": {
    "concurrency": {
      "repetitions": 10
    }
  }
}
```

### 7. Content and Message Handling

- **Validate message schemas** to ensure data integrity
- **Implement proper content type handling**
- **Use Parse JSON actions** to work with structured data

```json
"Parse_Response": {
  "type": "ParseJson",
  "inputs": {
    "content": "@body('HTTP_Request')",
    "schema": {
      "type": "object",
      "properties": {
        "id": {
          "type": "string"
        },
        "data": {
          "type": "array",
          "items": {
            "type": "object",
            "properties": { }
          }
        }
      }
    }
  }
}
```

### 8. Security Best Practices

- **Use managed identities** when possible
- **Store secrets in Key Vault**
- **Implement least privilege access** for connections
- **Secure API endpoints** with authentication
- **Implement IP restrictions** for HTTP triggers
- **Apply data encryption** for sensitive data in parameters and messages
- **Use Azure RBAC** to control access to Logic Apps resources
- **Conduct regular security reviews** of workflows and connections

```json
"Get_Secret": {
  "type": "ApiConnection",
  "inputs": {
    "host": {
      "connection": {
        "name": "@parameters('$connections')['keyvault']['connectionId']"
      }
    },
    "method": "get",
    "path": "/secrets/@{encodeURIComponent('apiKey')}/value"
  }
},
"Call_Protected_API": {
  "type": "Http",
  "inputs": {
    "method": "POST",
    "uri": "https://api.example.com/protected",
    "headers": {
      "Content-Type": "application/json",
      "Authorization": "Bearer @{body('Get_Secret')?['value']}"
    },
    "body": {
      "data": "@variables('processedData')"
    }
  },
  "authentication": {
    "type": "ManagedServiceIdentity"
  },
  "runAfter": {
    "Get_Secret": ["Succeeded"]
  }
}
```

## Performance Optimization

- **Minimize unnecessary actions**
- **Use batch operations** when available
- **Optimize expressions** to reduce complexity
- **Configure appropriate timeout values**
- **Implement pagination** for large data sets
- **Implement concurrency control** for parallelizable operations

```json
"Process_Items": {
  "type": "Foreach",
  "foreach": "@body('Get_Items')",
  "actions": {
    "Process_Single_Item": {
      "type": "Scope",
      "actions": { }
    }
  },
  "runAfter": {
    "Get_Items": ["Succeeded"]
  },
  "runtimeConfiguration": {
    "concurrency": {
      "repetitions": 10
    }
  }
}
```

### Workflow Design Best Practices

- **Limit workflows to 50 actions or less** for optimal designer performance
- **Split complex business logic** into multiple smaller workflows when necessary
- **Use deployment slots** for mission-critical logic apps that require zero downtime deployments
- **Avoid hardcoded properties** in trigger and action definitions
- **Add descriptive comments** to provide context about trigger and action definitions
- **Use built-in operations** when available instead of shared connectors for better performance
- **Use an Integration Account** for B2B scenarios and EDI message processing
- **Reuse workflow templates** for standard patterns across your organization
- **Avoid deep nesting** of scopes and actions to maintain readability

### Monitoring and Observability

- **Configure diagnostic settings** to capture workflow runs and metrics
- **Add tracking IDs** to correlate related workflow runs
- **Implement comprehensive logging** with appropriate detail levels
- **Set up alerts** for workflow failures and performance degradation
- **Use Application Insights** for end-to-end tracing and monitoring

## Platform Types and Considerations

### Azure Logic Apps vs Power Automate

While Azure Logic Apps and Power Automate share the same underlying workflow engine and language, they have different target audiences and capabilities:

- **Power Automate**: 
  - User-friendly interface for business users
  - Part of the Power Platform ecosystem
  - Integration with Microsoft 365 and Dynamics 365
  - Desktop flow capabilities for UI automation

- **Azure Logic Apps**:
  - Enterprise-grade integration platform
  - Developer-focused with advanced capabilities
  - Deeper Azure service integration
  - More extensive monitoring and operations capabilities

### Logic App Types

#### Consumption Logic Apps
- Pay-per-execution pricing model
- Serverless architecture
- Suitable for variable or unpredictable workloads

#### Standard Logic Apps
- Fixed pricing based on App Service Plan
- Predictable performance
- Local development support
- Integration with VNets

#### Integration Service Environment (ISE)
- Dedicated deployment environment
- Higher throughput and longer execution durations
- Direct access to VNet resources
- Isolated runtime environment

### Power Automate License Types
- **Power Automate per user plan**: For individual users
- **Power Automate per flow plan**: For specific workflows
- **Power Automate Process plan**: For RPA capabilities
- **Power Automate included with Office 365**: Limited capabilities for Office 365 users

## Common Integration Patterns

### Architectural Patterns
- **Mediator Pattern**: Use Logic Apps/Power Automate as an orchestration layer between systems
- **Content-Based Routing**: Route messages based on content to different destinations
- **Message Transformation**: Transform messages between formats (JSON, XML, EDI, etc.)
- **Scatter-Gather**: Distribute work in parallel and aggregate results
- **Protocol Bridging**: Connect systems with different protocols (REST, SOAP, FTP, etc.)
- **Claim Check**: Store large payloads externally in blob storage or databases
- **Saga Pattern**: Manage distributed transactions with compensating actions for failures
- **Choreography Pattern**: Coordinate multiple services without a central orchestrator

### Action Patterns
- **Asynchronous Processing Pattern**: For long-running operations
  ```json
  "LongRunningAction": {
    "type": "Http",
    "inputs": {
      "method": "POST",
      "uri": "https://api.example.com/longrunning",
      "body": { "data": "@triggerBody()" }
    },
    "retryPolicy": {
      "type": "fixed",
      "count": 3,
      "interval": "PT30S"
    }
  }
  ```

- **Webhook Pattern**: For callback-based processing
  ```json
  "WebhookAction": {
    "type": "ApiConnectionWebhook",
    "inputs": {
      "host": {
        "connection": {
          "name": "@parameters('$connections')['servicebus']['connectionId']"
        }
      },
      "body": {
        "content": "@triggerBody()"
      },
      "path": "/subscribe/topics/@{encodeURIComponent('mytopic')}/subscriptions/@{encodeURIComponent('mysubscription')}"
    }
  }
  ```

### Enterprise Integration Patterns
- **B2B Message Exchange**: Exchange EDI documents between trading partners (AS2, X12, EDIFACT)
- **Integration Account**: Use for storing and managing B2B artifacts (agreements, schemas, maps)
- **Rules Engine**: Implement complex business rules using the Azure Logic Apps Rules Engine
- **Message Validation**: Validate messages against schemas for compliance and data integrity
- **Transaction Processing**: Process business transactions with compensating transactions for rollback

## DevOps and CI/CD for Logic Apps

### Source Control and Versioning

- **Store Logic App definitions in source control** (Git, Azure DevOps, GitHub)
- **Use ARM templates** for deployment to multiple environments
- **Implement branching strategies** appropriate for your release cadence
- **Version your Logic Apps** using tags or version properties

### Automated Deployment

- **Use Azure DevOps pipelines** or GitHub Actions for automated deployments
- **Implement parameterization** for environment-specific values
- **Use deployment slots** for zero-downtime deployments
- **Include post-deployment validation** tests in your CI/CD pipeline

```yaml
# Example Azure DevOps YAML pipeline for Logic App deployment
trigger:
  branches:
    include:
    - main
    - release/*

pool:
  vmImage: 'ubuntu-latest'

steps:
- task: AzureResourceManagerTemplateDeployment@3
  inputs:
    deploymentScope: 'Resource Group'
    azureResourceManagerConnection: 'Your-Azure-Connection'
    subscriptionId: '$(subscriptionId)'
    action: 'Create Or Update Resource Group'
    resourceGroupName: '$(resourceGroupName)'
    location: '$(location)'
    templateLocation: 'Linked artifact'
    csmFile: '$(System.DefaultWorkingDirectory)/arm-templates/logicapp-template.json'
    csmParametersFile: '$(System.DefaultWorkingDirectory)/arm-templates/logicapp-parameters-$(Environment).json'
    deploymentMode: 'Incremental'
```

## Cross-Platform Considerations

When working with both Azure Logic Apps and Power Automate:

- **Export/Import Compatibility**: Flows can be exported from Power Automate and imported into Logic Apps, but some modifications may be required
- **Connector Differences**: Some connectors are available in one platform but not the other
- **Environment Isolation**: Power Automate environments provide isolation and may have different policies
- **ALM Practices**: Consider using Azure DevOps for Logic Apps and Solutions for Power Automate

### Migration Strategies

- **Assessment**: Evaluate complexity and suitability for migration
- **Connector Mapping**: Map connectors between platforms and identify gaps
- **Testing Strategy**: Implement parallel testing before cutover
- **Documentation**: Document all configuration changes for reference

```json
// Example Power Platform solution structure for Power Automate flows
{
  "SolutionName": "MyEnterpriseFlows",
  "Version": "1.0.0",
  "Flows": [
    {
      "Name": "OrderProcessingFlow",
      "Type": "Microsoft.Flow/flows",
      "Properties": {
        "DisplayName": "Order Processing Flow",
        "DefinitionData": {
          "$schema": "https://schema.management.azure.com/providers/Microsoft.Logic/schemas/2016-06-01/workflowdefinition.json#",
          "triggers": {
            "When_a_new_order_is_created": {
              "type": "ApiConnectionWebhook",
              "inputs": {
                "host": {
                  "connectionName": "shared_commondataserviceforapps",
                  "operationId": "SubscribeWebhookTrigger",
                  "apiId": "/providers/Microsoft.PowerApps/apis/shared_commondataserviceforapps"
                }
              }
            }
          },
          "actions": {
            // Actions would be defined here
          }
        }
      }
    }
  ]
}
```

## Practical Logic App Examples

### HTTP Request Handler with API Integration

This example demonstrates a Logic App that accepts an HTTP request, validates the input data, calls an external API, transforms the response, and returns a formatted result.

```json
{
  "definition": {
    "$schema": "https://schema.management.azure.com/providers/Microsoft.Logic/schemas/2016-06-01/workflowdefinition.json#",
    "actions": {
      "Validate_Input": {
        "type": "If",
        "expression": {
          "and": [
            {
              "not": {
                "equals": [
                  "@triggerBody()?['customerId']",
                  null
                ]
              }
            },
            {
              "not": {
                "equals": [
                  "@triggerBody()?['requestType']",
                  null
                ]
              }
            }
          ]
        },
        "actions": {
          "Get_Customer_Data": {
            "type": "Http",
            "inputs": {
              "method": "GET",
              "uri": "https://api.example.com/customers/@{triggerBody()?['customerId']}",
              "headers": {
                "Content-Type": "application/json",
                "Authorization": "Bearer @{body('Get_API_Key')?['value']}"
              }
            },
            "runAfter": {
              "Get_API_Key": [
                "Succeeded"
              ]
            }
          },
          "Get_API_Key": {
            "type": "ApiConnection",
            "inputs": {

                  "name": "@parameters('$connections')['keyvault']['connectionId']"
                }
              },
              "method": "get",
              "path": "/secrets/@{encodeURIComponent('apiKey')}/value"
            }
          },
          "Parse_Customer_Response": {
            "type": "ParseJson",
            "inputs": {
              "content": "@body('Get_Customer_Data')",
              "schema": {
                "type": "object",
                "properties": {
                  "id": { "type": "string" },
                  "name": { "type": "string" },
                  "email": { "type": "string" },
                  "status": { "type": "string" },
                  "createdDate": { "type": "string" },
                  "orders": {
                    "type": "array",
                    "items": {
                      "type": "object",
                      "properties": {

                        "amount": { "type": "number" }
                      }
                    }
                  }
                }
              }
            },
            "runAfter": {
              "Get_Customer_Data": [
                "Succeeded"
              ]
            }
          },
          "Switch_Request_Type": {
            "type": "Switch",
            "expression": "@triggerBody()?['requestType']",

## Advanced Exception Handling and Monitoring

### Comprehensive Exception Handling Strategy

Implement a multi-layered exception handling approach for robust workflows:

1. **Preventative Measures**:
   - Use schema validation for all incoming messages
   - Implement defensive expression evaluations using `coalesce()` and `?` operators
   - Add pre-condition checks before critical operations

2. **Runtime Error Handling**:
   - Use structured error handling scopes with nested try/catch patterns
   - Implement circuit breaker patterns for external dependencies
   - Capture and handle specific error types differently

      "runAfter": {
        "Try_Primary_Action": ["Succeeded"]
      }
    }
  }
}
```

3. **Centralized Error Logging**:
   - Create a dedicated Logic App for error handling that other workflows can call
   - Log errors with correlation IDs for traceability across systems
   - Categorize errors by type and severity for better analysis

### Advanced Monitoring Architecture

Implement a comprehensive monitoring strategy that covers:

1. **Operational Monitoring**:
   - **Health Probes**: Create dedicated health check workflows
   - **Heartbeat Patterns**: Implement periodic check-ins to verify system health
   - **Dead Letter Handling**: Process and analyze failed messages

2. **Business Process Monitoring**:
   - **Business Metrics**: Track key business KPIs (order processing times, approval rates)
   - **SLA Monitoring**: Measure performance against service level agreements
   - **Correlated Tracing**: Implement end-to-end transaction tracking

3. **Alerting Strategy**:
   - **Multi-channel Alerts**: Configure alerts to appropriate channels (email, SMS, Teams)
   - **Severity-based Routing**: Route alerts based on business impact
   - **Alert Correlation**: Group related alerts to prevent alert fatigue

                "name": "@parameters('$connections')['teams']['connectionId']"
              }
            },

        }
      }
    }
  }
}
```

## API Management Integration

Integrate Logic Apps with Azure API Management for enhanced security, governance, and management:

### API Management Frontend

- **Expose Logic Apps via API Management**:
  - Create API definitions for Logic App HTTP triggers
  - Apply consistent URL structures and versioning
  - Implement API policies for security and transformation

### Policy Templates for Logic Apps

```xml
<!-- Logic App API Policy Example -->
<policies>
  <inbound>
    <!-- Authentication -->
    <validate-jwt header-name="Authorization" failed-validation-httpcode="401" failed-validation-error-message="Unauthorized">
      <openid-config url="https://login.microsoftonline.com/{tenant-id}/.well-known/openid-configuration" />
      <required-claims>
        <claim name="aud" match="any">
          <value>api://mylogicapp</value>
        </claim>
      </required-claims>
    </validate-jwt>
    
    <!-- Rate limiting -->
    <rate-limit calls="5" renewal-period="60" />
    
    <!-- Request transformation -->
    <set-header name="Correlation-Id" exists-action="override">
      <value>@(context.RequestId)</value>
    </set-header>
    
    <!-- Logging -->
    <log-to-eventhub logger-id="api-logger">
      @{
        return new JObject(
          new JProperty("correlationId", context.RequestId),
          new JProperty("api", context.Api.Name),
          new JProperty("operation", context.Operation.Name),
          new JProperty("user", context.User.Email),
          new JProperty("ip", context.Request.IpAddress)
        ).ToString();
      }
    </log-to-eventhub>
  </inbound>
  <backend>
    <forward-request />
  </backend>
  <outbound>
    <!-- Response transformation -->
    <set-header name="X-Powered-By" exists-action="delete" />
  </outbound>
  <on-error>
    <base />
  </on-error>
</policies>
```

### Workflow as API Pattern

- **Implement Workflow as API pattern**:
  - Design Logic Apps specifically as API backends
  - Use request triggers with OpenAPI schemas
  - Apply consistent response patterns
  - Implement proper status codes and error handling

```json
"triggers": {
  "manual": {
    "type": "Request",
    "kind": "Http",
    "inputs": {
      "schema": {
        "$schema": "http://json-schema.org/draft-04/schema#",
        "type": "object",
        "properties": {
          "customerId": {
            "type": "string",
            "description": "The unique identifier for the customer"
          },
          "requestType": {
            "type": "string",
            "enum": ["Profile", "OrderSummary"],
            "description": "The type of request to process"
          }
        },
        "required": ["customerId", "requestType"]
      },
      "method": "POST"
    }
  }
}
```

## Versioning Strategies

Implement robust versioning approaches for Logic Apps and Power Automate flows:

### Versioning Patterns

1. **URI Path Versioning**:
   - Include version in HTTP trigger path (/api/v1/resource)
   - Maintain separate Logic Apps for each major version

2. **Parameter Versioning**:
   - Add version parameter to workflow definitions
   - Use conditional logic based on version parameter

3. **Side-by-Side Versioning**:
   - Deploy new versions alongside existing ones
   - Implement traffic routing between versions

### Version Migration Strategy

```json
"actions": {
  "Check_Request_Version": {
    "type": "Switch",
    "expression": "@triggerBody()?['apiVersion']",
    "cases": {
      "1.0": {
        "actions": {
          "Process_V1_Format": {
            "type": "Scope",
            "actions": { }
          }
        }
      },
      "2.0": {
        "actions": {
          "Process_V2_Format": {
            "type": "Scope",
            "actions": { }
          }
        }
      }
    },
    "default": {
      "actions": {
        "Return_Version_Error": {
          "type": "Response",
          "kind": "Http",
          "inputs": {
            "statusCode": 400,
            "body": {
              "error": "Unsupported API version",
              "supportedVersions": ["1.0", "2.0"]
            }
          }
        }
      }
    }
  }
}
```

### ARM Template Deployment for Different Versions

```json
{
  "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
  "contentVersion": "1.0.0.0",

    "logicAppName": {
      "type": "string",
      "metadata": {
        "description": "Base name of the Logic App"
      }
    },
    "version": {
      "type": "string",
      "metadata": {
        "description": "Version of the Logic App to deploy"
      },
      "allowedValues": ["v1", "v2", "v3"]
    }
  },

    "fullLogicAppName": "[concat(parameters('logicAppName'), '-', parameters('version'))]",
    "workflowDefinitionMap": {
      "v1": "[variables('v1Definition')]",
      "v2": "[variables('v2Definition')]",
      "v3": "[variables('v3Definition')]"
    },
    "v1Definition": {},
    "v2Definition": {},
    "v3Definition": {}
  },
  "resources": [
    {
      "type": "Microsoft.Logic/workflows",
      "apiVersion": "2019-05-01",
      "name": "[variables('fullLogicAppName')]",
      "location": "[resourceGroup().location]",
      "properties": {
        "definition": "[variables('workflowDefinitionMap')[parameters('version')]]"
      }
    }
  ]
}
```

## Cost Optimization Techniques

Implement strategies to optimize the cost of Logic Apps and Power Automate solutions:

### Logic Apps Consumption Optimization

1. **Trigger Optimization**:
   - Use batching in triggers to process multiple items in a single run
   - Implement proper recurrence intervals (avoid over-polling)
   - Use webhook-based triggers instead of polling triggers

2. **Action Optimization**:
   - Reduce action count by combining related operations
   - Use built-in functions instead of custom actions
   - Implement proper concurrency settings for foreach loops

3. **Data Transfer Optimization**:
   - Minimize payload sizes in HTTP requests/responses
   - Use local file operations instead of repeated API calls
   - Implement data compression for large payloads

### Logic Apps Standard (Workflow) Cost Optimization

1. **App Service Plan Selection**:
   - Right-size App Service Plans for workload requirements
   - Implement auto-scaling based on load patterns
   - Consider reserved instances for predictable workloads

2. **Resource Sharing**:
   - Consolidate workflows in shared App Service Plans
   - Implement shared connections and integration resources
   - Use integration accounts efficiently

### Power Automate Licensing Optimization

1. **License Type Selection**:
   - Choose appropriate license types based on workflow complexity
   - Implement proper user assignment for per-user plans
   - Consider premium connectors usage requirements

2. **API Call Reduction**:
   - Cache frequently accessed data
   - Implement batch processing for multiple records
   - Reduce trigger frequency for scheduled flows

### Cost Monitoring and Governance

```json
"Monitor_Execution_Costs": {
  "type": "ApiConnection",
  "inputs": {
    "host": {
      "connection": {
        "name": "@parameters('$connections')['loganalytics']['connectionId']"
      }
    },
    "method": "post",
    "body": {
      "LogType": "WorkflowCostMetrics",
      "WorkflowName": "@{workflow().name}",
      "ExecutionId": "@{workflow().run.id}",
      "ActionCount": "@{length(workflow().run.actions)}",
      "TriggerType": "@{workflow().triggers[0].kind}",
      "DataProcessedBytes": "@{workflow().run.transferred}",
      "ExecutionDurationSeconds": "@{div(workflow().run.duration, 'PT1S')}",
      "Timestamp": "@{utcNow()}"
    }
  },
  "runAfter": {
    "Main_Workflow_Actions": ["Succeeded", "Failed", "TimedOut"]
  }
}
```

## Enhanced Security Practices

Implement comprehensive security measures for Logic Apps and Power Automate workflows:

   - Apply encryption for data at rest and in transit

2. **Secure Parameter Handling**:
   - Use Azure Key Vault for all secrets and credentials
   - Implement dynamic parameter resolution at runtime
   - Apply parameter encryption for sensitive values

```json
"actions": {
  "Get_Database_Credentials": {
    "type": "ApiConnection",
    "inputs": {
      "host": {
        "connection": {
          "name": "@parameters('$connections')['keyvault']['connectionId']"
        }
      },
      "method": "get",
      "path": "/secrets/@{encodeURIComponent('database-connection-string')}/value"
    }
  },
  "Execute_Database_Query": {
    "type": "ApiConnection",
    "inputs": {
      "host": {
        "connection": {
          "name": "@parameters('$connections')['sql']['connectionId']"
        }
      },
      "method": "post",
      "path": "/datasets/default/query",
      "body": {
        "query": "SELECT * FROM Customers WHERE CustomerId = @CustomerId",
        "parameters": {
          "CustomerId": "@triggerBody()?['customerId']"
        },
        "connectionString": "@body('Get_Database_Credentials')?['value']"
      }
    },
    "runAfter": {
      "Get_Database_Credentials": ["Succeeded"]
    }
  }
}
```
