Mpesa Java SDK

Build Status Maven Central

A Java library for communicating with Mpesa Daraja rest API.

The SDK provides convenient access to the Mpesa Daraja API from applications written in Java.

Install

Maven

Use the following dependency in your project to grab via Maven:

 <dependency>
  <groupId>com.github.corneliouzbett</groupId>
  <artifactId>mpesa-sdk</artifactId>
  <version>1.1</version>
  <type>pom</type>
</dependency>

Gradle

For android developers you can install the library by adding dependency to build.gradle

implementation 'com.github.corneliouzbett:mpesa-sdk:1.1'

Gradle for Kotlin

For kotlin developers

implementation("com.github.corneliouzbett:mpesa-sdk:1.1")

Scala SBT

For developers using scala

libraryDependencies += "com.github.corneliouzbett" % "mpesa-sdk" % "1.1"

Usage

The SDK needs to be initialized with your consumer key and consumer secret, which you get from the safaricom developers portal. You are required to create an app.

You can use this SDK for either production or sandbox apps.

Initialize the client

  String consumerKey = "AXXXX-XXXX"; //consumer key
  String consumerSecret = "WEDX-XXXX-XXX-XXX"; //consumer secret

  Mpesa mpesa = new MpesaClient(consumerKey, consumerSecret); // initializing mpesa client

Authentication

Authenticate mpesa client and genarate accessToken used to access authorized resources (services) e.g C2B, B2C, MExpress, AccountBalance etc

mpesa.authenticate().getAccessToken().enqueue(new Callback<>() {

			@Override
			public void onResponse(Call<AccessToken> call, Response<AccessToken> response) {
				if (response.isSuccessful()) {
					String accessToken = response.body().getAccessToken();
				}
			}

			@Override
			public void onFailure(Call<AccessToken> call, Throwable throwable) {
				throw new MpesaException("Unable to authenticate Mpesa client", throwable);
			}
		});

Account Balance

This API entrypoint requests for the account balance of a shortcode (Till number).

  AccountBalance balance = new AccountBalance();
		balance.setCommandId("");
		balance.setInitiator("");
		balance.setIdentifierType("");
		balance.setPartyA("");
		balance.setQueueTimeOutURL("");
		balance.setResultUrl("");
		balance.setRemarks("");
		balance.setSecurityCredentials("");
  

MExpress

For Lipa Na M-Pesa payment using STK Push

  • Check status of lipa na mpesa payment
OnlinePaymentStatus paymentStatus =
   			new OnlinePaymentStatus(0000, "",
   					Timestamp.valueOf(LocalDateTime.now()), "");
 
   	mpesa.stkPush("accessToken").checkOnlinePaymentStatus(paymentStatus).enqueue(new Callback<>() {

   		@Override
   		public void onResponse(Call<OnlinePaymentStatusResponse> call, Response<OnlinePaymentStatusResponse> response) {

   		}

   		@Override
   		public void onFailure(Call<OnlinePaymentStatusResponse> call, Throwable throwable) {

   		}
   	});
  • Initiate stk push
 OnlinePayment onlinePayment = new OnlinePayment();
   	onlinePayment.setAccountReference("AccRef");
   	onlinePayment.setBusinessShortCode(123);
   	onlinePayment.setCallbackURL("callbackUrl");
   	onlinePayment.setAmount("amount");
   	onlinePayment.setPartyA("partyA");
   	onlinePayment.setPartyB("partyB");
   	onlinePayment.setPhoneNumber("phoneNumber");
   	onlinePayment.setPassword("passkey");
   	onlinePayment.setTimestamp("timestamp");
   	onlinePayment.setTransactionType("transaction type");
   	onlinePayment.setTransactionDescription("transaction desc");
   	
   	mpesa.stkPush("accessToken").initiateOnlinePayment(onlinePayment).enqueue(new Callback<OnlinePaymentResponse>() {

   		@Override
   		public void onResponse(Call<OnlinePaymentResponse> call, Response<OnlinePaymentResponse> response) {

   		}

   		@Override
   		public void onFailure(Call<OnlinePaymentResponse> call, Throwable throwable) {

   		}
   	});

C2B

This API entrypoint enables Paybill and Buy Goods merchants to integrate to M-Pesa and receive real time payments notifications

B2C

This API entrypoint enables Business to Customer (B2C) transactions between a company and customers who are the end-users of its products or services
