It is clear from various discussions that if I accept the credit card on my site and call Paypal API to pass the CC to Paypal, I have to be PCI compliant as well.
In our solution, user uses forms on our web page to submit credit card information. We then take these credit cards information, send them to Paypal, and receives an ID from paypal that we can store in the database. In future transactions, user does not need to enter the credit card information again. We simply send that ID to paypal in place of the credit card information.
To avoid the PCI nightmare, we want to rely of Paypal toodls/widgest to collect this credit card information in a way that we simply receive the corresponding IDs. The question is, does Paypal have such a widget? What are my options?
