The Bango Resale API is a RESTful API: you make requests, and the Bango Platform returns responses. However, in some cases the Bango Platform can send you updates without an explicit request from your code. There are three main use cases:
  • Users may be asked to complete a required merchant process before service activation or update. For example, a merchant may require a user to register for a service before activating the entitlement (and users may decline to complete the process).
  • Merchants can cancel or revoke entitlements at any time. For example, a merchant might cancel an entitlement if the user does not renew their subscription or cancels the service with the merchant directly, and it might revoke an entitlement if it detects fraudulent activity on the user’s account.
To receive a notification from the Bango Platform whenever a merchant or the Bango Platform changes an entitlement’s status for any reason, set the notificationUrl parameter when you create the entitlement (or later, by updating the entitlement). You must always set the notificationUrl. Invalid URLs trigger an HTTP 400 BAD_REQUEST response. The Bango Platform does not add or remove any query parameters from the URL you supply.
