**Scenario** : An issuer is integrating with ABU and would like to load a new account for the first time.   

**Description** : In this use case, `/addAccount` API is used to load the cardholder details for the first time in ABU. The response to `/addAccount` request confirms that the new account details are successfully sent to ABU. The `/requestStatus` API is then sent to confirm if the account was successfully added to ABU.

1. Issuer sends an `/addAccount` request to PAM API.
2. PAM API will send the update to ABU.
3. ABU will consume this account update and send a response to PAM API.
4. Issuer then sends a `/requestStatus` request to confirm if the account updates were successfully updated in ABU.
5. PAM API will then confirm this update to the issuer with a `requestStatus` response with a success or the specific error code received from ABU.
