Hi @MECUL Thanks for reaching out to us, According to the logs provided, your account doesn't seem to be PRO, apologies. In order to enable PRO on your account (there's a monthly fee involved), please contact our Agents in here More information: https://www.paypal.com/us/webapps/mpp/referral/paypal-payments-pro Regarding the error you get, just to clarify: When you receive the error "401 - UNAUTHORIZED_PAYMENT" it means that something in your REST API request is not passed correctly referring to the payment method. The payment method can be "paypal" for payments with a PayPal account and cards (only managed by PayPal checkout page where the buyer has to fill-in his card details on PayPal and not on your website) or "credit_card" for direct card payments where the buyer can provide his card details directly on your website (not on PayPal checkout). This last method is only reserved for PRO accounts in Uk, Us and Canada. I checked your API logs and I can see that you are passing: "payment_method": "credit_card" But as your account is not PRO you will receive this error. Pass the value "paypal" instead and you will able to process account card payments correctly as the buyer will log in into his/her PayPal account that will use the card already added in it or will be offered, where available, the Guest Checkout with card. Here a link with all the details: - https://developer.paypal.com/docs/api/payments/#payment_create - https://developer.paypal.com/docs/api/payments/#definition-payer If you would like to offer Direct Credit Card payment option, you might want to take a look at Braintree direct integration instead. Below I provide the documentation for this product: https://developer.paypal.com/docs/bt-direct-overview/ https://www.braintreepayments.com/en-gb?locale=en-gb I hope this helps, Thanks,
