How to implement a payment gateway to integrate with your website? :- www.deekpay.com

Payment gateways bring together all the stakeholders in a transaction - the buyer, the merchant, the buyer's bank and the seller's bank. This is why it takes longer for individuals to become fully proficient when implementing a payment gateway on their website. Payment gateway integration is crucial for the success of online transactions. Therefore, here we explain the API calls that usually occur when transactions are made through a payment gateway.

The above image shows the main integration steps.

API Integration Steps

Merchant Website

In order to initiate a transaction, the merchant generates a POST request (which is a specific interaction pattern on the Internet). The request must contain both required and optional parameters. The required fields include a key (provided by the gateway), a transaction ID (an order reference number generated on the merchant's end), an amount, product information, a name, an email, a phone number, a service provider, and a hash (checksum). The merchant also calculates a hash and sends it to the payment gateway.

PayU Payment Gateway Website

When the POST request reaches PayU, the customer is redirected to the payment page of the payment gateway (PayU). The customer now selects a specific payment option (Credit Card/Debit Card/Internet Banking etc.) on the PayU page and clicks on "Pay". At this point, the payment gateway redirects the customer to the selected bank. The customer completes the necessary authorisation/authentication process on the bank's login page and the bank returns the success/failure response to the payment gateway.

When a transaction POST request reaches the payment gateway server, a new transaction entry is created in the database. In order to identify each new transaction in the gateway database, a unique identifier is created on the gateway side each time.

Our payment gateway marks the status of the transaction based on the response received from the bank.

The final transaction response is sent to the merchant via a POST response. In this response, the merchant will receive the final status of the transaction. The merchant will also receive the hash parameters here. This is done to strictly prevent user tampering attempts.
