​
Get a bearer token

Exchanges a customer’s email address and password for a short-lived bearer token and a refresh token. Every authenticated API call in the Members Portal uses the access_token returned here as a Bearer credential. Pass totp when the customer has two-factor authentication enabled — omitting it when 2FA is active will return a two_factor_auth_check error.
Unlike most Nexudus API endpoints, this request must be encoded as application/x-www-form-urlencoded, not application/json. Sending a JSON body will result in an unsupported_grant_type error.

​
Authentication

No authentication required. This is the endpoint that issues credentials.

​
