Hi @gabrielfaleri
Thanks for reaching out to the Zoom Developer Forum, I am happy to help here!
It depends on what kind of application you are creating and what is the purpose of it.
You mentioned that you were able to enter rooms, do you mean meetings? What application did you use to call our endpoints?
So, if you are looking to create an internal application to manage meetings, users, webinars, etc from your account, you will be looking into a Server-to-Server Oauth app:
https://marketplace.zoom.us/docs/guides/build/server-to-server-oauth-app/
With this application you will request an access token to our Zoom Oauth endpoint and you will be able to use the token to call various endpoints (depending on the scopes you have added to your app)
If you are looking into an application that’s meant to be used by 3rd party user, then you will be looking into an OAuth app:
https://marketplace.zoom.us/docs/guides/build/oauth-app/
Lastly, if you are looking into embedding Zoom into your own application, then you will be looking into our SDK applications:
https://marketplace.zoom.us/docs/guides/build/sdk-app/
You can also create a Video SDK app that provides video, audio, screen sharing, chat, data streams, and more, as a service.

Let me know if this helps or if you need more clarification.
Best,
