"VAPI Webhook Triggering Multiple Times in Make.com – How to Resolve?"

How To
1

Hi everyone,

I’m working with VAPI and Make.com, and I’m encountering an issue where the webhook I’ve set up is being triggered multiple times without additional requests being made, it’s returning the same data over and over…

Here’s the situation:

  • I’ve set up a webhook in Make.com to handle VAPI requests. ( vapi ServerUrl )
  • The webhook is supposed to trigger only once per request, but it’s firing multiple times for a single request, causing duplicate executions in my scenario.

I’ve double-checked the setup on both VAPI and Make.com sides, and I can’t figure out why this is happening. Has anyone else experienced this issue? How can I ensure that the webhook only triggers once per request?

Any advice or troubleshooting tips would be greatly appreciated!

Hi,
Could you try turning on sequential processing in the scenario’s settings.
