I am setting up a cart for a client who is applying for the Paypal Website Payments Pro account.
Paypal has asked him to choose one of the following options:
Grant API Permission to your shopping cart or solution provider if the cart will make API calls on your behalf.
or
Request API Credentials to create an API username and password for either your preintegrated shopping cart or a custom solution that you are developing.
let me know which we need to choose.
Which one is best for Zencart?
