Adding Instamojo Payment Gateway

1. Sign Up for an Instamojo Account Visit Instamojo and sign up for an account if you don't have one already.

2. Create an API Key Once logged in, create an API Key by following Instamojo's documentation or developer resources.

3. Integrate Instamojo in Your Project Add the Instamojo Node.js library to your project: shell Copy code npm install instamojo-nodejs --save Import and configure the Instamojo library in your code: javascript Copy code const Instamojo = require('instamojo-nodejs'); const instamojo = new Instamojo({ apiKey: 'YOUR_API_KEY', authToken: 'YOUR_AUTH_TOKEN', endpoint: 'https://api.instamojo.com/v2/', }); Use the library to initiate payments.
