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

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.

Where do we update the scenario settings? I am having the same issue.

I updated the scenario setting to Yes. Still have the same problem.

I am still getting the message twice but that maybe something in the Assistant Script. Thanks a lot for your help.

One of my other assistant keep saying couldn’t get assistant when I call the number. I checked ana all the Server URL and Assistant is also connected. Any ideas?

Hi @copy_account,

Hi @Alex19,

Your webhook is triggering multiple times because there are multiple parameters in your server message. You can change it to trigger only on tool-call or your required action so that the webhook will activate only for tool-call or your required events.

You are receiving multiple requests because we believe there is also a status update included in your VAPI assistant’s server message.
