Hey @adil.aleem1281 Thanks for posting on the Zoom Devforum! I am still learning, but I will try my best to help answer your question. 🙂 Checkout these related threads that may have the answer you are looking for: > [@Add webinar registrant (with invalid webinar ID)](https://devforum.zoom.us/t/-/6284): > > Description/Error I’m seeing successful responses, HTTP status code 201 created, when calling the “add webinar registrant” endpoint with a non-existent webinar id. The documentation for responses, indicates we should receive HTTP status code 300 for an invalid webinar ID, or HTTP status code 404 not found (not sure which of these is right, but either of these would be better the current behaviour of a success result, and sending an email to registrant they have been added). Which Endpoint/s? … > [@Anyone can join webinar who has meeting Id](https://devforum.zoom.us/t/-/4730): > > We have created webinar and register user to webinar through api and api creates join link for the particular user, this is register webinar type. If anybody has Meeting Id then he can join webinar. How we restrict outside user who has meeting id to join webinar. (Only registered user can join webinar) If these threads did not help, please let us know by replying back here and someone from the Developer Relations team will get back to you shortly. Thanks, DeveloperBot ---

There was a parameter I forgot to use that’s why occurrences were not coming along with the webinar details. [https://api.zoom.us/v2/webinars/{webinar\_id}?show\_previous\_occurrences=true](https://api.zoom.us/v2/webinars/%7Bwebinar_id%7D?show_previous_occurrences=true) ---
