Common Patterns

API Integration:

[Trigger] → [API Request: Fetch data] → [Transform] → [CRM Manager: Update]

Sheet Logging:

[Any Trigger] → [Google Sheets: Append row with details]

Meeting Scheduling:

[Form Submit] → [Google Calendar: Check availability]
             → [Google Calendar: Create event]
             → [Email Send: Confirmation]

Lead Enrichment:

[New Contact] → [Apollo: Enrich person]
             → [CRM Manager: Update contact with enriched data]

Error Handling

Always check success and handle failures:

[API Request] → [Condition: {{apirequest_1.success}}]
             → true → [Continue workflow]
             → false → [Log error] → [Notify team]

Best Practices

1. Use variables in URLs - Build dynamic endpoints with {{node.field}}
2. Set appropriate timeouts - Prevent hanging on slow APIs
3. Handle rate limits - Use delays between bulk operations
4. Secure credentials - Use integrations, not hardcoded keys
5. Log API calls - Track requests for debugging
