How to Change GET Request to POST in Cashfree Payment Gateway: A Step-by-Step Guide

Are you tired of struggling with GET requests in Cashfree Payment Gateway? Do you want to switch to POST requests for added security and flexibility? Look no further! In this comprehensive guide, we’ll take you through the process of changing GET requests to POST requests in Cashfree Payment Gateway, step by step.

Why Switch to POST Requests?

Before we dive into the tutorial, let’s quickly explore why switching to POST requests is a good idea:

• Security: POST requests are more secure than GET requests since they don’t expose sensitive data in the URL. This reduces the risk of data tampering and phishing attacks.
• Flexibility: POST requests can handle larger datasets and are not limited by URL length constraints, making them ideal for complex payment gateway integrations.
• Compatibility: Many payment gateways, including Cashfree, recommend using POST requests for API calls to ensure seamless integration and error-free transactions.

Prerequisites

Before you start, make sure you have:

• A Cashfree Payment Gateway account with API credentials (API key and secret key)
• A basic understanding of HTML, CSS, and JavaScript (for modifying the payment gateway integration code)
• Your preferred coding environment set up (e.g., text editor, IDE, or code snippet platform)

Step 1: Understand the Current GET Request Structure

Take a closer look at your current GET request structure in Cashfree Payment Gateway. Identify the API endpoint, parameters, and any authentication mechanisms in place:

https://api.cashfree.com/pg/v1/checkout/order/? Amount=100&Order_Currency=INR&Order_Id=ORDER123&Return_URL=https://example.com/return

Note the URL structure, query parameters, and the HTTP method used (GET).

Step 2: Modify the API Endpoint to Support POST Requests

Update the API endpoint to accept POST requests by adding the `method` parameter to the request:

https://api.cashfree.com/pg/v1/checkout/order/

Set the `method` parameter to `post` to indicate that the request will be sent using the POST method:

https://api.cashfree.com/pg/v1/checkout/order/?method=post

Step 3: Convert Query Parameters to POST Body

Instead of passing query parameters in the URL, create a JSON object to hold the required data and send it in the request body:

{
  "Amount": 100,
  "Order_Currency": "INR",
  "Order_Id": "ORDER123",
  "Return_URL": "https://example.com/return"
}

This JSON object will be sent in the request body, replacing the query parameters.

Step 4: Update the Request Headers

Add the following headers to your request:

Header	Value
Content-Type	application/json
Authorization	Bearer YOUR_API_KEY

Replace `YOUR_API_KEY` with your actual Cashfree Payment Gateway API key.

Step 5: Send the POST Request

Using your preferred programming language or tool, send the POST request to the updated API endpoint:

fetch('https://api.cashfree.com/pg/v1/checkout/order/?method=post', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'Authorization': 'Bearer YOUR_API_KEY'
  },
  body: JSON.stringify({
    "Amount": 100,
    "Order_Currency": "INR",
    "Order_Id": "ORDER123",
    "Return_URL": "https://example.com/return"
  })
})

Make sure to replace `YOUR_API_KEY` with your actual API key.

Conclusion

By following these steps, you’ve successfully switched from a GET request to a POST request in Cashfree Payment Gateway. This change will provide added security, flexibility, and compatibility for your payment gateway integration.
