Given an email address and a password, generate an API authorization token. This token can be used with Bearer authorization when used together with the customer ID. (The customer ID is the same as the first number in the API server URL.)
Authorization: Bearer <customerid> <apitoken>Only "local" users that have a password can use this API; SSO users cannot log in using a password.
This endpoint does not itself need to Authorization header.
