Lipa Na Mpesa Online

A Nodejs implementation of Safaricom's Lipa na Mpesa Online Payment Api. Use this as a starting point template for your app.

Requirements

Credentials are required including:

• Consumer Key
• Consumer Secret
• Passkey

The consumer key & secret can be obtained by registering for an account here https://developer.safaricom.co.ke/ and once you have an account, the passkey can be got here https://developer.safaricom.co.ke/test_credentials

Installing

To automatically get the correct dependencies used in this project, ensure you have Node.js installed then:

1. Clone the project by running git clone https://github.com/petekmunz/Lipa-Na-Mpesa_Nodejs.git in your Git terminal.
2. In your terminal ensure you are in the directory Lipa-Na-Mpesa_Nodejs then run npm install

Pre-requirements

• Create a .env file in the root directory with the following variables.

NODE_ENV=development
MYPORT=3000                 //You can set to your preferrable port
CONSUMER_KEY=******************
CONSUMER_SECRET=***************
PASSKEY=***************
SHORTCODE=174379            //This is the test shortcode

• In the app.js file, replace the url here "CallBackURL": "http://example.com/api/v1/c2bconfirmation" with your actual callback url. The endpoint needs to be exposed to the internet if it is to receive a payload from Safaricom.

Running

• Make a POST request to the endpoint http://localhost:3000/mpesa with a JSON with the parameters as in the example below

{
    "phoneNumber":"254722xxxxxx",
    "amount":11
}

When all the required variables have been input, a succesful request will result in a STK push as shown below
