I have Created demo using PAYPAL REST API to collect payment in India with currency as USD from outside India.
In which set payment_method equals paypal_payment. During the payment processing user leave my website and go to PayPal payment page.
In PayPal payment page the user can pay using the card or his/her PayPal account. When I have tried with card payment, PAYPAL shows a screen with "back to merchant" button.
I can not get: what is the issue to do payment? why does PayPal not allow the card payment?
PayPal card payment using REST API is available only for US and UK merchant account. Reference
