I’m encountering issues with certain Billing Master API endpoints and could use some guidance. Specifically, I’m having trouble with the following endpoints:

1. **Get plan usage** : GET v2/accounts/{accountId}/plans/usage
2. **Subscribe account to an additional plan** : POST /v2/accounts/{accountId}/plans/addons
3. **Update an account’s additional plan** : PUT /v2/accounts/{accountId}/plans/addons

For the “ **Get plan usage** ” endpoint, I’ve successfully used “ **me** ” in place of **{accountId}** , which works as expected. However, **substituting my actual account ID always returns with a 404 not found exception**. Nonetheless, this isn’t a critical issue as using “me” suffices for this endpoint.

However, I’m encountering **persistent 404 exceptions** when attempting to use the next two endpoints, **regardless of whether I use “me” or my actual account ID**.

When using the problematic endpoints, I provide the following body:  
{“type”:“roomconnector\_monthly”,“hosts”:2}

It’s worth noting that the account ID I’m using is the same one employed during authentication to acquire the bearer auth token via:  
[https://zoom.us/oauth/token?grant\_type=account\_credentials&account\_id={accountId}](https://zoom.us/oauth/token?grant_type=account_credentials&account_id=%7BaccountId%7D)

Also, my Server-To-Server OAuth credentials have the required scopes attached for the endpoints: “billing:master” and “account:master”

It’s worth noting that I’m already subscribed to 1 “Conference Room Connector” plan.

Any assistance in resolving these issues would be greatly appreciated. Thank you!
