Duplicate MID Check

The Duplicate MID Check identifies if the MID that was used to create a new Sub-Account has been used for an existing Sub-Account:

• For this purpose a new parameter “merchantIdFound” was added to Create and Update Sub-Account methods in Sub-Account Management API.
• If a user calls “Create Sub-Account” method with a value in the “merchantId” field, the response will include a new object “merchantIdFound” that will be empty in case no “duplicate” MID for Sub-Accounts was found.
