Hello everyone,

I am developing a Zoom App that allows meeting and webinar participants to take a photo for biometric verification purposes. I have already tested the app within meetings, and it seems to be working correctly.

Now, I need to enable the app for webinars as well, but I don’t understand how to retrieve the webinar ID.

According to the [documentation](https://developers.zoom.us/docs/zoom-apps/zoom-app-context/#utilizing-the-decrypted-values), the ‘mid’ value is provided only within a meeting. How can I retrieve the webinar ID from the ‘X-Zoom-App-Context’ header?

Thank you.

Hi @bondaniniandrea , Meetings and Webinars function similarly, each using the same structure for ID & UUID. I would expect this header to also be returned within a Webinar.

> **[Zoom Apps for Webinars](https://developers.zoom.us/docs/zoom-apps/guides/webinar/)**

Hi @michael.zoom.

Thank you for your reply, I’ll try with the same structure.

Have a nice day.
