# n8n Workflow Patterns Proven architectural patterns for building n8n workflows. --- ## The 5 Core Patterns Based on analysis of real workflow usage: 1. **[Webhook Processing](webhook_processing.md)** (Most Common) - Receive HTTP requests → Process → Output - Pattern: Webhook → Validate → Transform → Respond/Notify 2. **[HTTP API Integration](http_api_integration.md)** - Fetch from REST APIs → Transform → Store/Use - Pattern: Trigger → HTTP Request → Transform → Action → Error Handler 3. **[Database Operations](database_operations.md)** - Read/Write/Sync database data - Pattern: Schedule → Query → Transform → Write → Verify 4. **[AI Agent Workflow](ai_agent_workflow.md)** - AI agents with tools and memory - Pattern: Trigger → AI Agent (Model + Tools + Memory) → Output 5. **[Scheduled Tasks](scheduled_tasks.md)** - Recurring automation workflows - Pattern: Schedule → Fetch → Process → Deliver → Log --- ## Pattern Selection Guide ### When to use each pattern: **Webhook Processing** - Use when: - Receiving data from external systems - Building integrations (Slack commands, form submissions, GitHub webhooks) - Need instant response to events - Example: "Receive Stripe payment webhook → Update database → Send confirmation" **HTTP API Integration** - Use when: - Fetching data from external APIs - Synchronizing with third-party services - Building data pipelines - Example: "Fetch GitHub issues → Transform → Create Jira tickets" **Databas...
