How to start

You’ll first need to intall nodemon, it is as simple as running npm install -g nodemon on your machine.

Below we describe the NodeJS integration for Cashfree PG. You’ll need Cashfree credentials for this setup to work. You can access the credentials from the merchant dashboard (API access > credentials) here.

Step 1

  • Open the file app.js, and update the value of the variable mode to “TEST”(for testing) or “PROD”(for production) depending on your environment (line 36).
  • Update the variable secretKey with the correct value for the mode you have selected in the app.js file (line number 37 and 67).

Step 2

Once you’ve installed nodemon in your system and updated the file with the correct secretKey values. Run the following commands from the folder where you have the app.js file, this will start your server.

nodemon --exec npm start
Card Number : 4111 1111 1111 1111
