npm install razcrypto-node
Quick Start
1. Initialize the API
JavaScript
const RazCrypto = require('razcrypto-node');

const razcrypto = new RazCrypto("YOUR_GATEWAY_ID", "YOUR_SECRET_KEY");
2. Create a Payment
JavaScript
async function createOrder() {
    try {
        const payment = await razcrypto.payment.create({
            amount: 10.50,
            currency: 'USDT',
            chain: 'BSC',
            email: 'customer@example.com',
            callback_url: '[https://yourwebsite.com/webhook](https://yourwebsite.com/webhook)',
            custom_data: {
                order_id: 'ORD-12345'
            }
        });

        console.log("Checkout URL:", payment.checkout_page);
        // Redirect your user to this URL
    } catch (error) {
        console.error("Error:", error.message);
    }
}
3. Verify Webhook (Express.js Example)
Always verify the webhook signature to ensure security.

JavaScript
const express = require('express');
const app = express();
// Note: Use express.raw() or express.text() if you need the raw body for signature matching
app.use(express.json()); 

app.post('/webhook', (req, res) => {
    const signature = req.headers['x-razcrypto-signature'];
    const rawPayload = JSON.stringify(req.body); // Ensure this matches raw incoming payload
    const secretKey = "YOUR_SECRET_KEY";

    const isValid = RazCrypto.Webhook.verifySignature(rawPayload, signature, secretKey);

    if (isValid) {
        const data = req.body;
        if (data.event === 'payment.completed') {
            const orderId = data.custom_data.order_id;
            // TODO: Mark order as paid in database
        }
        res.status(200).send({ status: 'ok' });
    } else {
        res.status(401).send({ error: 'Invalid Signature' });
    }
});
