Hownd Partner API
A secured REST API that lets an approved Hownd partner manage Subscribers on behalf of Hownd customers (merchants and businesses). Partners are issued OAuth 2.0 client credentials and retrieve a bearer token from the company's Auth0 tenant using the client_credentials grant with the audience https://partner-api.hownd.com. Every call carries an X-Tenant-Id header that identifies which Hownd merchant is being acted on. Hownd states the credentials are server-to-server only and must not be used from a browser or mobile application. Creating a subscriber requires an email address; first name, last name and phone number are optional. No OpenAPI or public reference is published; the surface is documented only by the first-party example repository below.
