Hello Zapians,

I plan to register users for my WebinarJam sessions by using a Zapier Webhook, but I always get the an error.

Here is my static test setup:
I use this static values to make sure that the Webhook is working correct before I handover the data from my form.


This is a straight forward static test, but it fails :sweat:


Here is the error that I get:

Here is WebinarJam API documentation:

I am looking forward to get a few tips.

Hi @jayeshkumarbhatia, I switched the order of the parameters, it didn’t slove my issue, but it make sense to follow the same order as in the original documentation :thumbsup:

Hi @Troy Tessalone, I switched to JSON which kind of helped me in the problem solving process, see following solution. :trophy:


I had the following mistakes in my Zap setup:

Thank you for your help and ideas.

My final setup:
