Hi everyone,
Whenever I use Webhooks by Zapier to send a POST request to an external API (like ManyChat’s), if something fails, Zapier always shows the same message:
❌ Failed to create a request in Webhooks by Zapier
The app returned “Validation error”.
This is extremely generic, and it’s the same message no matter what the actual issue is. But when I test the same request in Postman, I get a helpful error body from the API — for example, it might say something like “Missing phone number” or “Invalid field format,” which lets me fix the issue immediately.
My questions are:
-
Is there any way in Zapier to see the full API response, especially the message body?
-
Could Zapier expose the raw error from the API in the task log, console, or anywhere behind the scenes?
-
Is this something other users have run into? How are you debugging around this?
I’d love any workarounds, tips, or clarification. Right now, I’m spending a lot of time guessing what went wrong because all I get is “Validation error.”
Thanks!
