PayPal Integrations - DoReferenceTransaction and DoAuthorization -
We have a requirement where we pay out automatic Payments for PayPal payment for next scheduled order with user contact Need to run
We use AGREEMENTID by using this billing to get the user that we can process during the first transaction.
My question is that we just need "DoReferenceTransactionReq" or even after that we need to do DoAuthorization. . 1.SetExpressCheckoutReq 2.GetExpressCheckoutDetailsReq 3.DoExpressCheckOutPaymentReq
if you have gone through already express Checkout flow and there is made a sale or authorization transaction, then you need to do is process the new amount DoReferenceTransaction is in that transaction ID passes. DoAuthorization is just making a fresh authentication and is not necessary to run the reference transaction.
