Here's a step-by-step guide focusing on using a payment integration API. ### Step 1: Choose the Right Payment Gateway When selecting a gateway, consider factors like transaction fees, supported payment methods, and customer support. Axra is a modern, developer-friendly platform offering competitive rates and comprehensive support. ### Step 2: Register and Obtain API Credentials Once you choose a gateway, register an account to obtain your API credentials, which typically include an API key and secret. ### Step 3: Set Up Your Development Environment Ensure your environment is ready for API integration. For JavaScript developers, Node.js is a popular choice. ### Step 4: Code the Integration #### JavaScript/Node.js Example Below is a basic example of integrating a payment gateway using Node.js: ```javascript const axios = require('axios'); const apiKey = 'your_api_key'; const apiSecret = 'your_api_secret'; async function processPayment(amount, currency, source) { try { const response = await axios.post('https://api.axra.com/v1/payments', { amount, currency, source }, { headers: { 'Authorization': `Bearer ${apiKey}:${apiSecret}` } }); console.log('Payment successful:', response.data); } catch (error) { console.error('Error processing payment:', error); } } processPayment(5000, 'USD', 'card_1J2mZb2eZvKYlo2C'); ``` #### cURL Example For testing purposes, you can use cURL to make API requests: ```bash curl -X POST https://api.axra.com/v1/payments \ -u your_api_key:your_api_secret \ -d amount=5000 \ -d currency=USD \ -d source=card_1J2mZb2eZvKYlo2C ``` ### Step 5: Implement Frontend Integration For frontend integration, HTML forms can capture payment details: ```html
