**Description**  
When we register a listener to a webinar, we get the join\_url specific for that person. How long is it valid? Forever or can it change/time out? We were asked to put it in an ical file and this would make sense if it stays valid “forever”.

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

**Which Endpoint/s?**  
/webinars/{webinarId}/registrants

Hey @jahrralf,

The join\_url for meetings or webinar is valid until the webinar has ended and expired.

Thanks,  
Tommy
