Zapier MCP Server

Task limit exceeded or Zap throttled without clear error

Check Dashboard > Usage for daily/monthly task quotas. Each action counts as one task. Zaps throttled if exceeding plan limits or burst thresholds. Add Delay after Queue step to manage rate. Upgrade plan for higher limits.

API rate limit errors from connected apps

Check app-specific API usage limits in Zap History. Batch tasks where possible. Implement delays between steps (Delay action). Upgrade app plan if hitting external service limits. Use webhooks instead of polling triggers.

Zap fails with authentication or connection errors

Use Zap History to inspect failed tasks and error codes. Reauthenticate accounts if credentials expired. Check app connection status in My Apps. Verify OAuth redirect URLs correct. Test connection with sample trigger.

Data formatting or missing field errors in multi-step Zaps

Check payloads in Zap History for missing/malformed data. Use Formatter to transform data between steps. Verify required fields mapped correctly. Test each step individually. Enable detailed logging for debugging.
