Authorization Workflow

This image and description provide information about the authorization workflow:

The customer purchases goods or service from the merchant using a payment card.

The merchant sends an authorization request to

the acquiring (merchant) bank

.

The acquiring (merchant) bank

forwards the authorization request to the payment network.

The payment network forwards the authorization request to the issuer (customer) bank.

If funds are available, the issuer (customer) bank reserves the amount of the authorization request and returns an authorization approval to the payment network. If the issuer (customer) bank denies the request, it returns an authorization denial.

The payment network forwards the message to

the acquiring (merchant) bank

.

The acquiring (merchant) bank

forwards the message to the merchant.
