Hi! I’m using the Zoom API using curl to create meetings, register users, etc. When it comes to authentification, I’m using the firebase [JWT library](https://github.com/firebase/php-jwt) to create a token which I then use in my Authorization header. I know that the JWT app is supposed to be deprecated on June 1, but is the authentification using firebase still going to work? I’m trying to figure out whether or not I need to convert to Server-to-Server OAuth app before that date. I’ve seen posts on these forums that says it should be fine, but it’s not 100% clear. If someone could help me validate, it would be much appreciated. Thanks! ---

@pierrealexislebrun, Welcome to the Zoom Developer Forum – I am happy to help. You are correct; The [JWT app type](https://marketplace.zoom.us/docs/guides/build/jwt-app/jwt-faq) will be deprecated on June 1, 2023. To avoid any service disruption, you will want to migrate to Server-to-Server OAuth app before that date. To learn more about this topic, please see our support documentation below: # Resources: ### JWT app type migration guide [https://marketplace.zoom.us/docs/guides/build/jwt-app/jwt-app-migration/](https://marketplace.zoom.us/docs/guides/build/jwt-app/jwt-app-migration/) ### JWT App Type Deprecation FAQ [https://marketplace.zoom.us/docs/guides/build/jwt-app/jwt-faq/#jwt-app-type-deprecation-faq--omit-in-toc-](https://marketplace.zoom.us/docs/guides/build/jwt-app/jwt-faq/#jwt-app-type-deprecation-faq--omit-in-toc-) ### Create a Server-to-Server OAuth app [https://marketplace.zoom.us/docs/guides/build/server-to-server-oauth-app/](https://marketplace.zoom.us/docs/guides/build/server-to-server-oauth-app/) Let me know if you have any questions about this. ---

It is so for the app type, but someone from support said [here](https://devforum.zoom.us/t/jwt-apps-to-be-deprecated-in-favor-of-server-to-server-oauth/69319/16) that we would still be able to use JWT credentials. It’s not very clear what will still be usable and what won’t ---

Hello? Is anyone going to clarify? ---

Go to the [Created Apps](https://marketplace.zoom.us/user/build) page and look for any products where the **Type** column shows **JWT**. Those are the applications that will stop working. You can temporarily deactivate the app yourself to test the impact. You can still use JWT signatures for the Meeting SDK app type. ---
