Error 2013-Zoom Phone has not been enabled for this account

Just getting started with experimenting with Zoom API, in particular the phone api.
We have about 80 users using Zoom phone as our telephony solution. I have logged into Zoom portal with the main admin email and have created a ‘Server to Server Oauth App’ with scope to read call logs and access recordings.
Using postman I have successfully authenticated using the client id and secret and have a valid access token. When I use the access token in postman to get some basic user information I get the response “Zoom Phone has not been enabled for this account”.
I also notice in the postman response that the scope response is “marketplace:delete:event_subscription marketplace:read:list_event_subscriptions marketplace:update:event_subscription marketplace:write:event_subscription marketplace:write:websocket_connection” and dosent seem to tie up with the scope I defined when creating the app.
The admin account/email has a “Zoom Phone Pro” license.
Is there something I’m missing.
Thanks
Brian

Hi @BrianH
Thanks for reaching out to us and welcome to the Zoom Developer Community!
I am happy to help here!
Could you please make sure that you are generating your token correctly?

Hi Elisa
Thanks for that. Realized I didn’t have the account id in the POST request.
Thanks for your help.
Regards
