How to Integrate Payment Gateways to Websites

Integrating payment gateways to your web application or websites is a very simple process

there are mainly two ways of implementing payment gateways to your application

one is by using the an API method and other is redirecting to the payment gateway site and return after the payment is completed

in API method the card details ,cvv, exp date are entered in our site and its validated and make  a payment

for making API our site need to be verified by PCI , that is we are not storing the card no and its details in our database then only the PCI will certify our application.

In redirect method we will send the user to the payment gateway site and the user enters all the card details there and the payment gateway returns the transcation number and some details we have passed this method is more safe compared to an api method

in payment there are mainly two type of payment that is get paid at the time the user submits the card details (CAPTURE method)and the other method is charged after some time or days after submitting the card details (AUTHORISE method)

The CAPTURE method this method is useful for online electronics or those items those price change in mins In those condition the amount will be immediately taken from the users card

in the AUTHORISE method the money will be Authorise by the payment gateway ie the users money is taken by the payment gateway but not send to the merchants account only after a time the merchants application will communicate with the payment gateway and collect the amount this mainly for tipping deal sites (ie when a required amount of users by a items other wise the money will be send to user )
