The 5 Core Patterns

Based on analysis of real workflow usage:

1. Webhook Processing (Most Common)

• Receive HTTP requests → Process → Output
• Pattern: Webhook → Validate → Transform → Respond/Notify

1. [HTTP API Integration]

• Fetch from REST APIs → Transform → Store/Use
• Pattern: Trigger → HTTP Request → Transform → Action → Error Handler

1. Database Operations

• Read/Write/Sync database data
• Pattern: Schedule → Query → Transform → Write → Verify

1. AI Agent Workflow

• AI agents with tools and memory
• Pattern: Trigger → AI Agent (Model + Tools + Memory) → Output

1. Scheduled Tasks

• 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: "Recei
