Routes

Have a look on Highlighted area,That CALLBACK_URL is same as tha route defined below that InitializeTransaction is called

Keep in mind

When InitializeTransaction is called it require two properties included in POST request of body from the form defaultValue

  • orderId (req.body.orderId)
  • amount (req.body.amount)
    So keep that note and dont forget to pass these properties as defined , otherwise it wll throw an error
    You cannot change these properties.
index.js
const express = require("express");
const app = express();
const path = require("path");
const bodyParser = require("body-parser");
app.use(bodyParser.json());
const { PaytmConfig } = require("../dist/Fixe");
app.use(express.json());
app.use(bodyParser.urlencoded({ extended: true }));

const paytm = new PaytmConfig({
  PAYTM_ENVIRONMENT: "LIVE",
  PAYTM_MERCHANT_KEY: "YOUR PAYTM_MERCHANT_KEY",
  PAYTM_MERCHANT_ID: " YOUR PAYTM_MERCHANT_ID",
  PAYTM_MERCHANT_WEBSITE: "DEFAULT",
  CALLBACK_URL: "http://localhost:8080/callback",
});
 
app.get("/", (req, res) => {
  res.sendFile(path.join(__dirname, "/index.html"));
});
app.post("/paynow", paytm.InitializeTransaction);
app.post("/callback",(req, res) => console.log(req.body) );
app.listen(8080, () => console.log("http://localhost:8080"));
