Rest Api

I need to import a large number of users on a large number of sites.

I am using the rest API and this endpoint, on a paid Premium-package site:

https://public-api.wordpress.com/wp/v2/sites/123/users (blog id modified for privacy)

This is the error I receive.

{“code”:”forbidden_request”,”message”:”That API call is not allowed for this account.”,”data”:{“status”:403}}

I have a valid access token and believe I have the appropriate permissions.

Any ideas?
