We are planning to integrate to PayPal with following requirements:
- We collect card based payments for US customers.
- We are planning to integrate with Payflow Gateway with "Sage" as our processor.
- We will have customers who will allow us to charge them on a periodic basis (replenishment with Card on file).
Questions:
Is Payflow Gateway suitable for our requirements?
Does Payflow Gateway has a REST based interface? How do we tokenize (card on file) without keeping card numbers with us?
If "reference transaction" is the only way to do Card on file operation, how do we overcome the expiry period (1 year) of referenced transaction?
