I know that it is possible to save the paypal information of a user for future payments. For example: When a user orders food at an online delivery service, the user can save his paypal information and the next time he orders food he must not login to paypal again.
I think what I am looking for is called “Billing Agreement” within the PayPal REST API. What this does not work without a “Billing Plan”, which seems to be for subscritions (recurring payments with the same amount in certain time intervals).
Is Billing Agreement the thing I am looking for?
Thank you very much!
