JavaScript M-Pesa SDK

This is a library willing to help you to integrate the Vodacom M-Pesa operations to your application.

Features

Using this library, you can implement the following operations:

• Receive money from a mobile account to a business account (C2B)
• Send money from a business account to a mobile account (B2C)
• Send money from a business account to another business account (B2B)
• Revert any of the transactions above mentioned
• Query the status of a transaction

Requirements

• NodeJS v12.0+
• NPM or Yarn
• Valid credentials obtained from the Mpesa Developer portal

Installation

Using NPM

npm install --save @paymentsds/mpesa

Using Yarn

yarn add @paymentsds/mpesa

Usage

Using this SDK is very simple and fast, let us see some examples:

Client configuration

import { Client } from '@paymentsds/mpesa'

const client = new Client({
   apiKey: '<REPLACE>',              // API Key
   publicKey: '<REPLACE>',           // Public Key
   serviceProviderCode: '<REPLACE>', // Service Provider Code,
   initiatorIdentifier: '<REPLACE>', // Initiator Identifier,
   securityIdentifier: '<REPLACE>',  // Security Credential
   timeout: '<REPLACE>',             // time in seconds
   debugging: true,                 
   verifySSL: false,
   userAgent: '<REPLACE>' 
});

C2B Transaction (Receive money from mobile account)

On ES6 Modules

import { Client } from '@paymentsds/mpesa'

const client = new Client({
   apiKey: '<REPLACE>',             // API Key
   publicKey: '<REPLACE>',          // Public Key
   serviceProviderCode: '<REPLACE>' // Service Provider Code
});

const paymentData = {
   from: '841234567',               // Customer MSISDN
   reference: '11114',              // Third Party Reference
   transaction: 'T12344CC',          // Transaction Reference
   amount: '10'                     // Amount
};

client.receive(paymentData).then(r => {
   // Handle success scenario
}).catch(e =>{
   // Handle success scenario
});

CommonJS

var Client = require("@paymentsds/mpesa").Client;

   serviceProviderCode: '<REPLACE>', // Service Provider Code,
   initiatorIdentifier: '<REPLACE>', // Initiator Identifier,
   securityCredential: '<REPLACE>'  // Security Credential
});

const reversionData = {
   reference: '11114',           // Third Party Reference
   transaction: 'T12344CC',       // Transaction ID
   amount: '10'                  // Reversal Amount
};

client.revert(reversionData).then(r => {
   // Handle success scenario
}).catch(e =>{
   // Handle failure scenario
});

CommonJS

let Client = require("@paymentsds/mpesa").Client;

let client = new Client({
   apiKey: '<REPLACE>',             // API Key
   publicKey: '<REPLACE>',          // Public Key
   serviceProviderCode: '<REPLACE>', // Service Provider Code,
   initiatorIdentifier: '<REPLACE>', // Initiator Identifier,
   securityCredential: '<REPLACE>'  // Security Credential
});

let reversionData = {
   reference: '11114',           // Third Party Reference
   transaction: 'T12344CC',       // Transaction ID
   amount: '10'                  // Reversal Amount
};

client.revert(reversionData).then(function(r) {
   // Handle success scenario
}).catch(function(e) {
   // Handle failure scenario
});

Query the transaction status

On ES6 Modules

import { Client } from '@paymentsds/mpesa'

const client = new Client({
   apiKey: '<REPLACE>',             // API Key
   publicKey: '<REPLACE>',          // Public Key
   serviceProviderCode: '<REPLACE>', // Service Provider Code,
});

const reversionData = {
   reference: '11114', // Third Party Reference
   subject: '5C1400CVRO', // Query Reference
};

client.query(reversionData).then(r => {
   // Handle success scenario
}).catch(e => {
   // Handle failure scenario
});

CommonJS

let Client = require('@paymentsds/mpesa');

let client = new Client({
   apiKey: '<REPLACE>',             // API Key
   publicKey: '<REPLACE>',          // Public Key
   serviceProviderCode: '<REPLACE>', // Service Provider Code,
});

let reversionData = {
   reference: '11114', // Third Party Reference
   subject: '5C1400CVRO', // Query Reference
};

client.query(reversionData).then(function(r) {
   // Handle success scenario
}).catch(function(e) {
   // Handle failure scenario
});
