Submerchant Update

This service allows you to update submerchant accounts by providing their necessary details.

In the process of updating submerchants, it's important to note that you cannot change the submerchant type. Once a submerchant is created with a specific type, it cannot be modified to a different type. Therefore, it's crucial to ensure that the correct submerchant type is selected during the initial setup.

All of the submerchant types are capable of update operations;

• PERSONAL

• PRIVATE COMPANY

• LIMITED OR JOINT STOCK COMPANY
