I have given the Buyer’s email address of the existing Customer, and I have entered the Order details with the Customer Id of the existing Customer whereas Customer Id is optional. I have generated the Checkout link with these details and placed the order.
A new Customer is created with the buyer’s email address and Payment linked to the newly created Customer.
Payment should be linked to the existing Customer (As I have passed the Customer Id in request).
How can I achieve this?
Thanks in advance!
