Beside this, what does it mean when it says transaction declined Gateway rejected?

Moreover, what does Gateway response mismatch mean?
An AVS mismatch is when the billing address provided at checkout does not match the billing address or payment credentials on file with the card issuer.
"Transaction declined" means that, for whatever reason, your creditor is declining the purchase. Often, this is due to being over the credit limit or not having enough funds for the transaction, but it could also be a card hold for security reasons. In addition, this could happen due to an AVS mismatch.
