Greetings Zoom, We have Education (Pro) Plan, for users with username@ourcampus.edu. However, somehow all the users now have Basic Licences, do you happen to know what caused this change, and how it can be fixed? I already opened a ticket with ZOOM. We have over 11K users, we are not using API for licences. Thanks. ---

Hey @nvanderson, Not sure how this happened. I will direct this to the proper team as this forum is for questions about the Zoom App Marketplace and APIs. You should hear back from the ticket you submitted from [support.zoom.us](http://support.zoom.us). Apologies this happened, Tommy ---

I am still waiting for the response…also a question about API for you. Can JWT be used for this call to update the licence? [https://marketplace.zoom.us/docs/api-reference/zoom-api/users/userupdate](https://marketplace.zoom.us/docs/api-reference/zoom-api/users/userupdate) I am getting 400 error with JWT. If I must use OAuth, since I just need a licence updated. [https://marketplace.zoom.us/docs/guides/authorization/oauth/quickstart](https://marketplace.zoom.us/docs/guides/authorization/oauth/quickstart) What can I put for re-direct url for OAuth? And last question: from Admin panel, can all users licences be updated, and not 1 by 1? [https://fullerton.zoom.us/account/user](https://fullerton.zoom.us/account/user) ---

Yes, check the check box to select all users then bulk update them: ![56%20PM](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/2X/b/b0b6bdf5d9b9804820affad30008d1c59c4ede8e.png) Thanks, Tommy ---
