Trying to run a cc, but transaction won't go through. Code 5012. All cc info is correct. How to resolve?

Hi, MPI1. I'm here to help you resolve this error code 5012 and get back to running the transaction seamlessly.

This error occurs when the client's bank requires a call verification from the cardholder, and it might be due to a missing code. I recommend reaching out to your bank to authorize this payment. If a PIN is required, ensure it is entered correctly.
