## Approving a Purchase Request
1) The customer completes their shopping experience on the merchant's website by selecting the products or services.
They navigate to the checkout page on the merchant's website.
2) They enter their personal and payment information. This could include card details, or net banking information.
3) The merchant's website captures these details, formatting the details as needed to conform to Flute payment gateway requirements.
4) This sensitive data is transmitted by a secure connection (HTTPS) to the Flute payment gateway.
The Flute payment gateway is a service that makes authorization and sale by cards or ACH (automated clearing house, an electronic network used by financial institutions to process direct deposits).
5) Upon receiving this information, the Flute payment gateway further routes this payment data to the processing center, such as TSYS.
6) This entity communicates with the customer's bank to get authorization or denial for the payment.
The processing center determines if the payment is approved, that is, if there are sufficient funds or credit available in the customer's account.
