I’m following Mackenzie Child’s tutorial on creating a Webflow membership program using Zap and custom webhook. I’ve followed it to the letter and looked on the forums to problem solve but I somehow keep getting a Validation error w. a webhook PATCH.  

Here’s my Zap

And Here’s the Webflow Collection it is Linked to


If anyone has any ideas what I’m doing wrong I will send you a cinnabon.

Hi @Esteban 

Looks like your array object [doesn’t have double quotes around the items].


Also based on your screenshot of the PATCH Webhooks step, it’s unclear if you have the other required headers

Hello @ Troy.  Thank you for getting back to me.  It’s great to know that there’s an amazing community out here to support us learners.  And I actually fixed it!  I ended up reverting to an old webflow build shortly after working things out the first time and it ended up changing all of my piece ID’s.  

All good now though! Thank you!
