Help using Paypal SDK to put paypal accounts on file as authorized, and bill when needed.
I have a website . I want my members to be able to:
~ authorize a credit card or paypal account and maintain it on file
~ then members can freely purchase from the website without needing to relogin to paypal or to re-enter their credit card number.
I am hoping there is a secure way to do this.
I am unsure if I need to be using the Paypal Classic API or The REST-SDK-API .
I also do not know if this is to be a Paypal Payments Pro or Payments Standard option....or just something custom.
If these things sound familiar to you, then I could use your help.
