Paypal API integration for debit and Credit card with Node JS - reactjs

Question

I am tiring to add credit debit card integration that are already saved in our database and I don't want user to fill those information to the paypal debit/credit card payment form.
I want to know
Is there a way to auto populate information from my database to paypal from?
Or how can I use orders API to directly pass the information to the paypal using API integration.
The Paypal really is a mess. Can anyone please help me in the integration.
NOTE : I am using React JS as front-end and nestjs as back-end.

Answer 1

You can't populate a form, and storing credit card information in your database is a potentially problematic practice you should review (better to tokenize/vault it) and requires a full PCI self-assessment review.
But as for how to send credit cards to PayPal via an API, if anaccount is enabled for Advanced Credit and Debit Card processing, the below might allow you to use the v2/checkout/orders API with card details in the payment_source object
(Edit: apparently more permissions are needed from PayPal for this)
