// Workflow definition snippet: HTTP trigger
{
  'definition': {
    'triggers': {
      'manual': {
        'type': 'Request',
        'kind': 'Http',

작업 및 커넥터

// Workflow: send an email via Office 365 after HTTP trigger
// Actions section of the workflow definition:
{
  'Send_an_email': {
    'type': 'ApiConnection',
    'inputs': {
      'host': { 'connection': { 'name': '@parameters("$connections")["office365"]["connectionId"]' } },
      'method': 'post',
      'path': '/v2/Mail',
      'body': {
        'To': 'manager@contoso.com',
        'Subject': 'New Order from @{triggerBody()["customerName"]}',
        'Body': 'Order total: @{triggerBody()["orderTotal"]}'
      }
    }
  }
}

제어 흐름: 조건 및 반복

// Condition action in workflow definition
{
  'Check_order_value': {
    'type': 'If',
    'expression': {
      'and': [{
        'greater': ['@triggerBody()["orderTotal"]', 1000]
      }]
    },
    'actions': {
      'Notify_Manager': { /* send email action */ }
    },
    'else': {
      'actions': {
        'Auto_Approve': { /* approve action */ }
      }
    }
  }
}

표현식 및 함수

// Expression examples in Logic Apps actions
// Reference trigger data
'@triggerBody()["customerName"]'

// String manipulation
'@toUpper(triggerBody()["customerName"])'

// Date operations
'@addDays(utcNow(), 7)' // One week from now

// Reference previous action output
'@outputs("Get_customer")["body"]["email"]'

// Conditional expression
'@if(greater(triggerBody()["total"], 1000), "VIP", "Standard")'

오류 처리: Run After 및 재시도

// Action that runs only when a previous action fails
{
  'Send_failure_alert': {
    'type': 'ApiConnection',
    'runAfter': {
      'Process_order': ['Failed', 'TimedOut']
    },
    'inputs': { /* Teams notification */ },
    'operationOptions': 'DisableAsyncPattern',
    'runtimeConfiguration': {
      'staticResult': null
    }
  }
}

Azure 서비스와의 통합

// Azure Blob trigger + SQL Database action pattern
// Trigger: 'When a blob is added or modified'
// Action 1: Read blob contents
// Action 2: Parse CSV/JSON body
// Action 3: 'Insert row' into Azure SQL Database
// Action 4: 'Delete blob' from source container
// Action 5: Send success notification email
//
// No custom code required for this common ETL pattern

모니터링 및 실행 기록

# Enable diagnostic logging for a Logic App

  --resource '/subscriptions/.../providers/Microsoft.Logic/workflows/MyLogicApp' \
  --name 'LogAnalyticsLogs' \
  --workspace /subscriptions/.../workspaces/MyLogAnalytics \
  --logs '[{"category": "WorkflowRuntime", "enabled": true, "retentionPolicy": {"days": 30, "enabled": true}}]'
