Add a hidden field that sends data back via the webhook

I have a working webhook to send attendee and registration data back. I need to associate webinars with campaign. Webinars 1,2,3 are part of Campaign1 as an example - just need that campaign name returned in the webhook. Is this possible?

Hi @valerie
Thanks for reaching out to us and welcome to the Zoom Developer Community!
In our webinar.registration_approved webhook, there is a tracking source field that might be useful for you.
Other than that I don’t think what you are trying to achieve is possible

Let me know if this helps!
