Well, I was mistaken in assuming that the error could be caused using CC direct payment.
As follows from the document:
- You need to create a test user account
- Log in to the sandbox using the above account.
- Change the address of the test CC user to:
CCREJECT-REFUSED
Then, to test it, start the express delivery flow, as usual. But in the last part, do not use direct CC input . Instead, choose another option - log in to your userβs PayPal account .
Then you will get the following answer: TIMESTAMP=2013%2d08%2d19T06%3a50%3a45Z&CORRELATIONID=6761aff7944b&ACK=Failure&VERSION=104&BUILD=7319395&L_ERRORCODE0=10486&L_SHORTMESSAGE0=This%20transaction%20couldn%27t%20be%20completed%2e&L_LONGMESSAGE0=This%20transaction%20couldn%27t%20be%20completed%2e%20Please%20redirect%20your%20customer%20to%20PayPal%2e&L_SEVERITYCODE0=Error
