How to Handle Webhook Errors in Make.com

Description and use

Make.com automation workflows often fail due to incomplete or unexpected data. The author recommends inspecting webhook payloads, validating required fields, logging events, separating critical from optional actions, and using unique IDs to avoid duplicates. This results in reliable, maintainable processes.

Problem

Webhook-based Make.com workflows frequently break due to incomplete or unexpected data, missing fields, or downstream service failures.

Outcome

Workflows become resilient to data inconsistencies, reduce duplicate records, and provide clear logs for troubleshooting, leading to smoother automation operations.

Workflow

• Check webhook output for received data
• Identify missing or unexpected fields
• Validate required fields before proceeding
• Separate critical actions from optional ones
• Add logging of inputs, outputs, and failures
• Implement duplicate event checks using unique identifiers
• Handle common errors (missing data, API timeouts, service outages) with simple branches
• Keep workflow structure minimal and clear
• Test with varied real-world scenarios
• Iterate fixes on smallest issue first
• Rebuild workflow only if structure is too complex
