What MPESA G2 API should have been in the 21st century.

MPESA API RESTful mediator. Basically converts all merchant requests to the dreaded ancient SOAP/XML requests. It then mediates all communications to and from the Safaricom MPESA gateway frictionlessly. Responding to the merchant via a beautiful and soothing 21st century REST API.

In short, it'll deal with all of the SOAP shenanigans while you REST. 😄

The aim of Project Mulla, is to create a REST API that interfaces with the ugly MPESA G2 API.

Yes We Know! SOAP! Yuck!

Developers should not go through the trauma involved with dealing with SOAP/XML in the 21st century.

Example of how it works

Once Project Mulla is set up, up and running in whichever clould platform you prefer(we recommend Heroku.com). Your 1st request once your customer/client has consumed your services or purchasing products from you is to innitiate a payment request.

Initiate Payment Request:

Method: POST

Endpoint: https://awesome-service.com/api/v1/payment/request

Parameters:

• phoneNumber - The phone number of your client
• totalAmount - The total amount you are charging the client
• referenceID - The reference ID of the order or service [optional; one is generated for you if missing]
• merchantTransactionID - This specific order's or service's transaction ID [optional; one is generated for you if missing]

Response:

Installation

Dependencies

You will need to install some stuff, if they are not yet in your machine:

Majors:

• Node.js (v4.4.4 LTS) - Click here to install

Secondaries(click for further information):

• NPM (v3.5+; bundled with node.js installation package)

You may need to update it to the latest version:

$ npm update -g npm

Getting Started

Once you have Node.js installed, run (type or copy & paste; pick your poison):

To download the boilerplate

$ git clone https://github.com/kn9ts/project-mulla

After cloning, get into your project mulla's directory/folder:

$ cd project-mulla

Install all of the projects dependecies with:

$ npm install

Create .env configurations file

The last but not least step is creating a .env file with your configurations in the root directory of project mulla.

Should be in the same location as index.js

It should look like the example below, only with your specific config values:

API_VERSION = 1
HOST = localhost
PORT = 3000
EXPRESS_SESSION_KEY = '88186735405ab8d59f968ed4dab89da5515'
WEB_TOKEN_SECRET = 'a7f3f061-197f-4d94-bcfc-0fa72fc2d897'
PAYBILL_NUMBER = '898998'
PASSKEY = 'ab8d88186735405ab8d59f968ed4dab891588186735405ab8d59asku8'
ENDPOINT = 'https://safaricom.co.ke/mpesa_online/lnmo_checkout_server.php?wsdl'
CALLBACK_URL = 'http://awesome-service.com/mpesa/confirm-checkout.php'
CALLBACK_METHOD = 'POST'
TEST_PHONENUMBER = '0720000000'
TEST_AMOUNT = '10.00'

It's now ready to launch

$ npm start

> project-mulla@0.1.1 start ../project-mulla
> node index.js

Express server listening on 3000, in development mode
Mongoose has connected to the database specified.

Do a test run

You can make a test run using CURL:

$ curl -i -X POST \
  --url http://localhost:3000/api/v1/payment/request \
  --data 'phoneNumber=254723001575' \
  --data 'totalAmount=450.00' \
  --data 'clientName="Eugene Mutai"' \
  --data 'clientLocation=Kilimani' \

Or if you have httpie installed:

$ http POST localhost:3000/api/v1/payment/request \
  phoneNumber=254723001575 \
  totalAmount=450.00 \
  clientName='Eugene Mutai' \
  clientLocation='Kilimani'

You should expect back a similar structured response as follows:
