Hi everyone I want to integrate the PayPal api I did all the setups etc but I get this error when I get to the final stage of the payment: problem setting up this payment and I don't understand why since I followed all the steps that I found online.
This is the error:
DEBUG: E/paypal.sdk: request failure with http statusCode:422,exception: request failed with server response:{"name":"PAYMENT_CREATION_ERROR","debug_id":"9c95c8e6d1a65","message":"checkout-session not created","information_link":"https://developer.paypal.com/docs/api/#PAYMENT_CREATION_ERROR"} E/paypal.sdk: PAYMENT_CREATION_ERROR
