Storing and Using the Reference ID

Once the reference_id is received:

✅ Store it in your database to track the payment.

✅ Retrieve the payment URL and redirect the customer to complete the payment.

💡 Example Backend Code (Node.js - Express.js):

Example Backend Code

const express = require("express");
const axios = require("axios");
const app = express();
app.use(express.json());

const PAYRAM_API_URL = "<http://yourpayramserver.com:8080/api/v1/payment>";
const API_KEY = "ad9db0a5e2e720eaa07a573b4142b51b"; //use your respective api key

app.post("/initiate-payment", async (req, res) => {
    try {
        const { customerEmail, customerId, amountInUSD } = req.body;

        const response = await axios.post(PAYRAM_API_URL, {
            customerEmail,
            customerId,
            amountInUSD
        }, {
            headers: { "API-Key": API_KEY, "Content-Type": "application/json" }
        });

        const { reference_id, url } = response.data;

        // Store reference_id in database for tracking
        console.log("Payment Reference ID:", reference_id);

        res.json({ reference_id, url }); // Send payment URL back to the frontend
    } catch (error) {
        console.error("Error initiating payment:", error);
        res.status(500).json({ error: "Failed to generate payment link" });
    }
});

app.listen(3000, () => console.log("Server running on port 3000"));
