Here is a basic guide to integrating PayUmoney Payment Gateway into a PHP application:
Sign up for a PayUmoney account: To get started, sign up for a PayUmoney account and get your merchant key and salt.
Create a payment form: Create a payment form with input fields for the required payment details, such as the amount, product name, and customer name.
Hash calculation: To secure the transaction, PayUmoney requires a hash to be sent along with the payment details. The hash is calculated using the merchant key and salt, along with the payment details.
PHP code for generating the hash:
Submit the form to the PayUmoney server: The form should be submitted to the PayUmoney server using the action attribute of the form tag, with the URL set to https://secure.payu.in/_payment.
Handle success and failure responses: PayUmoney will send a response back to your website after the payment is processed. You should have separate PHP scripts to handle success and failure responses and update your database accordingly.
Test the integration: Test the integration thoroughly by making multiple test payments with different amounts and different payment options, such as credit card, debit card, and net banking.
This is just a basic guide to help you get started with integrating PayUmoney Payment Gateway into a PHP application. You may need to make additional modifications and optimizations to meet your specific requirements.
