Phonepe Payment Gateway Integration In Php-Implementing Razorpay Payment Gateway Integration in Android Apps for Indian Transactions

Integrating the Razorpay payment gateway into an Android app for processing Indian transactions involves several steps. Below is a high-level overview of the process, which includes setting up your environment, integrating the SDK, and handling the payment flow.

### Step 1: Register and Set Up Razorpay Account

1. **Create an Account**: Sign up for a Razorpay account at [https://razorpay.com](https://razorpay.com).

2. **Get API Keys**: Once your account is set up, you will receive API keys, which include a Key ID and a Secret Key. Keep these keys secure as they are used to authenticate your requests.

### Step 2: Add Dependencies

In your `build.gradle` (Module: app) file, add the Razorpay SDK dependency:

“`gradle

dependencies {

// Other dependencies

implementation ‘com.razorpay:razorpay:2.0.0’

}

“`

Sync your project with the Gradle files.

### Step 3: Request Permissions

In your AndroidManifest.xml, add the necessary permissions for network access:

“`xml

“`

### Step 4: Initialize Razorpay

In your activity or fragment where you want to initiate the payment, initialize the Razorpay instance:

“`java

Razorpay razorpay = new Razorpay(this);

“`

### Step 5: Start Payment Process

To start the payment process, you will need to create a `JSONObject` with the necessary payment details:

“`java

JSONObject options = new JSONObject();

try {

// You can get these details from your backend

options.put(“name”, “Your Company Name”);

options.put(“description”, “Order #123456”);

options.put(“image”, “https://example.com/logo.png”);

options.put(“order_id”, “ORDER_ID_FROM_YOUR_SERVER”); // This should be generated by your backend

options.put(“currency”, “INR”);

options.put(“amount”, “10000”); // Amount in the smallest currency unit (e.g., 100 for Rs.100)

razorpay.startPaymentActivity(this, options);

} catch (JSONException e) {

e.printStackTrace();

}

“`

### Step 6: Handle Payment Result

Override the `onActivityResult` method in your activity to handle the payment result:

“`java

@Override

protected void onActivityResult(int requestCode, int resultCode, Intent data) {

super.onActivityResult(requestCode, resultCode, data);

if (requestCode == RazorpayActivity.REQUEST_CODE_PAYMENT) {

if (resultCode == RESULT_OK) {

// Payment success

Toast.makeText(this, “Payment Success”, Toast.LENGTH_SHORT).show();

} else if (resultCode == RESULT_CANCELED) {

// Payment cancelled

Toast.makeText(this, “Payment Cancelled”, Toast.LENGTH_SHORT).show();

} else if (resultCode == RazorpayActivity.RESULT_ERROR) {

// Payment error

Toast.makeText(this, “Payment Error”, Toast.LENGTH_SHORT).show();

}

}

}

“`

### Step 7: Backend Integration

The `order_id` used in the payment process must be generated by your backend server. This ensures that the payment is processed securely and that you can verify the payment on your server.

1. **Generate Order**: Use the Razorpay API to generate an order ID on your server.

2. **Verify Payment**: After the payment is completed, Razorpay sends a webhook notification to your server. You should verify the payment with Razorpay’s API to ensure it’s legitimate.

### Step 8: Testing

Before going live, thoroughly test the payment flow in a test environment provided by Razorpay. Ensure that you handle all possible scenarios, including success, failure, and cancellation.

### Step 9: Go Live

Once you have tested the payment flow and are confident that everything is working as expected, you can go live by using your live API keys and deploying your app.

Remember to follow best practices for security, such as not storing sensitive data on the device and ensuring that all communication with your server is over HTTPS.

Please note that the above steps are a simplified guide. Always refer to the official Razorpay documentation for the most up-to-date and detailed integration steps.

Icegate E Payment Gateway-Integrating Stripe Payment Gateway with CodeIgniter for Indian Market： A Comprehensive Guide

Integrating Stripe with CodeIgniter for the Indian market involves setting up Stripe’s API in your CodeIgniter application to handle payments. Stripe is a popular choice for online payment processing due to its simplicity and the variety of features it offers. Below is a comprehensive guide to help you integrate Stripe with CodeIgniter for use in the Indian market.

### Prerequisites:

1. **CodeIgniter installed**: You should have CodeIgniter set up and running.

2. **Stripe Account**: Create an account on Stripe and set up your API keys.

3. **PHP cURL**: Ensure PHP cURL is enabled on your server as it’s required for making HTTP requests to Stripe’s API.

### Step 1: Install Stripe PHP Library

You can install the Stripe PHP library using Composer. If you haven’t already set up Composer, you’ll need to do that first.

In your project root, run:

“`bash

composer require stripe/stripe-php

“`

### Step 2: Configure Stripe API Keys

After installing the Stripe PHP library, you need to configure your Stripe API keys. These keys can be found in your Stripe Dashboard.

Create a new file `stripe.php` in the `application/config` directory of your CodeIgniter application with the following content:

“`php

load->config(‘stripe’);

“`

### Step 4: Create a Payment Method

To charge a customer, you first need to create a payment method. This usually involves collecting the user’s credit card details securely. Stripe provides a JavaScript library called Stripe.js to handle this.

Include Stripe.js in your view file:

“`html

“`

Then, create a form to collect card details:

“`html

Credit or debit card

“`

Initialize Stripe.js with your publishable key and mount the card element:

“`javascript

var stripe = Stripe(‘config->item(‘stripe_key_publishable’); ?>’);

var elements = stripe.elements();

var card = elements.create(‘card’);

card.mount(‘#card-element’);

// Add event listener to the form

var form = document.getElementById(‘payment-form’);

form.addEventListener(‘submit’, function(event) {

event.preventDefault();

stripe.createToken(card).then(function(result) {

if (result.error) {

// Inform the user if there was an error

var errorElement = document.getElementById(‘card-errors’);

errorElement.textContent = result.error.message;

} else {

// Send the token to your server

stripeTokenHandler(result.token);

}

});

});

function stripeTokenHandler(token) {

// Insert the token ID into the form so it gets submitted to your server

var hiddenInput = document.createElement(‘input’);

hiddenInput.setAttribute(‘type’, ‘hidden’);

hiddenInput.setAttribute(‘name’, ‘stripeToken’);

hiddenInput.setAttribute(‘value’, token.id);

form.appendChild(hiddenInput);

// Submit the form

form.submit();

}

“`

### Step 5: Handle the Payment on the Server

In your controller, create a function to handle the payment:

“`php

public function charge() {

$this->load->config(‘stripe’);

require_once APPPATH . ‘third_party/stripe/stripe-php/init.php’;

// Retrieve the request’s body and parse it as JSON

$body = @file_get_contents(‘php://input’);

$json = json_decode($body, true);

// Set API key

\Stripe\Stripe::setApiKey($this->config->item(‘stripe_key_secret’));

// Get the credit card token submitted by Stripe.js

$token = $json[‘stripeToken’];

// Charge the user’s card

try {

$charge = \Stripe\Charge::create(array(

‘amount’ => 1000, // amount in paise, for INR currency

‘currency’ => ‘inr’,

‘description’ => ‘Example charge’,

‘source’ => $token,

));

echo json_encode(array(“status” => “success”, “charge” => $charge));

} catch(\Stripe\Error\Card $e) {

// The card has been declined

echo json_encode(array(“status” => “declined”, “error” => $e->getMessage()));

}

}

“`

Make sure to replace `1000` with the actual amount in paise (1 INR = 100 paise) and `’inr’` with the currency code you are using.

### Step 6: Test Your Integration

Before going live, thoroughly test your payment flow in the test environment provided by Stripe. Ensure that you handle all possible scenarios, including declined cards and network errors.

### Step 7: Go Live

Once you’ve tested your integration and are ready to go live, replace your test API keys with your live API keys and make sure your application is secure, especially since you’re handling sensitive payment information.

Remember to comply with the Reserve Bank of India’s guidelines and other regulations that apply to online payment transactions in India.

### Security and Compliance

– Always use HTTPS to protect card data.

– Follow PCI DSS guidelines to ensure that your handling of card data is secure.

– Do not store card details on your server; let Stripe handle that securely.

This guide provides a basic outline for integrating Stripe with CodeIgniter for the Indian market. Depending on your specific requirements, you may need to add additional functionality or handle more complex scenarios. Always refer to the Stripe documentation for the most up-to-date and detailed information.
