Zapier errors / Schema
Status Code 400 Bad Request
Cause
The destination app rejected the request because a required field was missing, empty, or in an unrecognised format (e.g. a name in an email field).
Fix
Open the Zap history entry, click the failing action, and inspect Data In to find the bad value. Strip optional fields and test with required fields only to isolate the problem field. Add a Formatter to convert the value to the expected format. Re-enable optional fields one at a time.
