Hi I am getting the following error while upserting data into payment information. I am using PaymentInformationDetailV3 API to upsert the data.
<message>Save batch MDF object failed! 0:Sorry, you should provide only one main payment method. with the index 0</message>
I have seen that in SF, there is already one record exists. I am upserting again. So how can i increase the value of index from 0 to 1. Please help me. Thanks in advance.
