Obtain OAuth access token

Request an OAuth 2.0 access token using your credentials. This token must be included in the Authorization header for all V1 API requests.

Authentication Flow:

1. Send your credentials to this endpoint
2. Receive an access token in the response
3. Include the token in subsequent requests: Authorization: Bearer {token}

Token Expiration: Tokens expire after a set period. Monitor the passwordExpired field and request a new token when needed.
