How does a payment gateway work?

A payment gateway plays three major roles in online payment transactions:

Authorise – It validates the customer’s payment (credit or debit card) information.

Transfer – It transfers the validated information to the Internet Merchant Account for approval.

Report – It records all the details of the transactions that took place.

It then reports back to the customer with the result of the assessment.

Successful – a receipt will be issued. You should check the confirmation email.

Declined – this may be due to insufficient funds. You should discuss this with your bank.

Error – incorrect information. You will have to try again.
