Step-by-Step Integration Process

Step 1: Create a Payment Gateway Account

Begin by setting up an account with your chosen payment gateway. For instance, if you're opting for Axra, visit their website and complete the registration process.

Step 2: Obtain API Credentials

API credentials are essential for your application to communicate with the payment gateway. These typically include a public key and a secret key.

Step 3: Implement Backend Integration

Integrate the payment gateway with your server-side logic to handle transactions securely.

#### Node.js Example

Here's a basic example of integrating Axra using Node.js:

javascript

17 lines

const axios = require('axios');

const processPayment = async (amount, currency) => {
  const response = await axios.post('https://api.axra.com/v1/payments', {
    amount: amount,
    currency: currency,
  }, {
    headers: {
      'Authorization': `Bearer YOUR_SECRET_KEY`
    }
  });
  return response.data;
};

processPayment(100, 'USD')
  .then(data => console.log(data))
  .catch(error => console.error(error));

Step 4: Test with cURL

Testing your integration with cURL can ensure that your API requests are functioning correctly.

#### cURL Example

bash

4 lines

curl -X POST https://api.axra.com/v1/payments \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_SECRET_KEY" \
  -d '{"amount": 100, "currency": "USD"}'

Step 5: Integrate Frontend Payment Form

A well-designed payment form is critical for user experience. Use HTML and JavaScript to create a secure, seamless checkout process.

#### HTML Example

html

6 lines

<form id="payment-form">
  <input type="text" id="card-number" placeholder="Card Number" required>
  <input type="text" id="expiry-date" placeholder="Expiry Date (MM/YY)" required>
  <input type="text" id="cvv" placeholder="CVV" required>
  <button type="submit">Pay Now</button>
</form>
