I am using the PayPal REST API and would like to create a transaction that includes a combination of recurring and one-time payments in a single transaction.
According to the documentation for the NVP integration, it seems such a transaction is possible. However, I'm not sure how to accomplish the same using the REST API. I have searched the REST API documentation as well as the .NET SDK examples and cannot find an example of a transaction that uses a mix of recurring and one-time payments.
Our use case: We process transactions for downloadable software - most of the products are one-time purchases, but some of the products (such as anti-virus products) have a recurring billing component associated with them. As such, we need to process a single transaction where one of the items is a regular purchase, and the other is a part of a recurring plan. We plan to process these transactions using the "PayPal" payment method (i.e. not direct credit card). Specifically, we'll be using Express Checkout.
Any guidance would be much appreciated. Thank you!
