Clarification on handling webinar registrations

I am trying to sync my app’s booking processes with Zoom’s webinar registrant status and I would like to make sure I understand my options there. The API documentation is somewhat lacking in this regard.

For example: gives no indication which values the field “status” can have. lists the possible values as approved, pending, denied. indicates I can PUT a status of approve, cancel and deny.

Which App Type (OAuth / Chatbot / JWT / Webhook)?

Which Endpoint/s?

Additional context
So, from what I have gathered from my own issues and #34478 so far is that:

The only way for me to get someone into the status of pending through the API is to newly register them. Using the /webinars/{webinarId}/registrants/status endpoint, my only options are setting a user to approved or denied. Using the status of cancel is indistinguishable from using deny as a user will end up with a denied status in any event. This means subsequent attempts to re-register this user using the same e-mail address will fail.

Our use case is that we usually register users to a webinar in a pending state and approve their registration once the requirements are met on our side (usually payment). That works well so far if this is done in order - register = status pending, payment = status approved. If however, the payment is confirmed in error, there currently is no way for us to truly undo the approval and set it back to a pending state. We can neither just set a status of pending, nor can we actually delete the registration and re-register them so they achieve pending status. We have to mark them as denied, which is equivalent to “blocked”, right?

And one last thing: On the Zoom website, when administering the webinar, at least the German version lists the status of users who are pending as approval (which is not a German word), it’s not another possible status though, right?

Hey @philvdb,

Thank you for reaching out to the Zoom Developer Forum. I definitely understand the issue here. If a user’s payment is denied, you can cancel the registration. Once their payment processes successfully, you can then use the Update a Webinar Registrant Status API. We cover this in a previous post:

In regard to the incorrect German translation, please reach out to our Customer Support team as they will be able to assist you directly with that issue.

I hope that helps! Let me know if you have any questions.


Hello again @MaxM, thank you for your reply.

That is what I have been doing, thank you for confirming that this is the “proper” way.

I’m afraid you seem to have pasted the wrong link there?

Thank you for your support

Hey @philvdb,

Good catch! Sorry about posting the link to this thread, I’m not sure how that happened but I suppose it wasn’t very helpful regardless. I’ve updated the link in my previous post to what I meant to send, it essentially goes over the Update a Webinar Registrant Status API call that you would make.
