I faced a problem (error) when I create payment endpoint the error is:
"{"detail":"400: {'name': 'COMPLIANCE_VIOLATION', 'message': 'Transaction is declined due to compliance violation.', 'information_link': 'https://developer.paypal.com/docs/api/payments/v1/#error-COMPLIANCE_VIOLATION', 'debug_id': 'cf7fd8c0fd383'}"} "I searched about this error and I found that it is caused by many reasons such as:
- the currency
- restrictions on the sandbox account
- the value of the order is greater than in the accountbut I checked those reasons then the same error and checked client_ID and client_secret
I use paypalrestsdk library.
I made a static web page that make on it the checkout.
I am from egypt default paypal currency EUR.
I expected to process this payment only to test the feature.
