M-pesa SDK

M-pesa sdk is an unofficial sdk with the aim to make it easy to integrate with the Vodacom Mozambique M-pesa payments api on android apps.

Usage

Getting M-Pesa Credentials

Create an account on the Vodacom Mozambique M-pesa website in order to get the credentials and full documentation of the API

Core

This library provides the core components to perform the network operation to the M-pesa api. This is the library that powers the ui library and you can use it to create your own ui implementation of the SDK that better suits your project needs.

This library makes the network calls using Retrofit and the responses are adapter to RxJava2 types using the RxJava2Adapter.

Create an M-pesa service

fun createMpesaService(): MpesaService {
   val config = MpesaConfig(baseUrl = API_BASE_URL, apiKey = apiKey, publicKey = publicKey)
   val repository = MpesaRepositoryImpl(config)
   return MpesaMpesaServiceImpl(repository)
}

Make a payment request

Create a payment request

val paymentRequest = PaymentRequest(
   input_Amount = amount,
   input_CustomerMSISDN = "25884$phoneNumber",
   input_ThirdPartyReference = thirdPartyReference,
   input_ServiceProviderCode = serviceProviderCode,
   input_TransactionReference = transactionReference)

Perform the network call

 val mpesaService = createMpesaService()
 val disposable = mpesaService.pay(paymentRequest)
                .subscribe { response, throwable -> handleResponse(response, throwable) }

Handle the response

private fun handleResponse(response: PaymentResponse?, throwable: Throwable?) {
   response?.run {
       val responseCode = response.output_ResponseCode
           when (responseCode) {
                //Do Something depending on the response code
           }
       }

   throwable?.run {
       when (throwable) {
           is HttpException -> {
               val json = throwable.response().errorBody()?.string()
               val response = Gson().fromJson(json, PaymentResponse::class.java)
                    //Do something
           }
           is UnknownHostException -> {
                //Do something
           }
           is SocketTimeoutException -> {
                    //Do Something
           }
       }
   }
}

Ui

This library allows the easy integration of the M-pesa payments on an android app with a ui backed by the core library that handles everything needed to make a payment.

Initialize the SDK

Initialize the SDK on the Application onCreate callback. Note: Calling init more than once will throw an IllegalStateException.

MpesaSdk.init(
   apiKey = "m_pesa_api_key",
   publicKey = "your_public_key",
   endpointUrl = "the_endpoint_url",
   serviceProviderCode = "m_pesa_service_provider_code",
   serviceProviderName = "service_provider_company_display_name",
   serviceProviderLogoUrl = "https://www.vodacom.co.za/vodacom/home/images/header/vodacom_icon.77b545abd1d7a4e0808b5a2255438f64.png")

Note: The endpoint url's for the sandbox and production environment are constants in the MpesaSdk with the names SANDBOX_BASE_URL and PRODUCTION_BASE_URL respectively.

Make Payment

Make the payment by calling the pay provided by the M-pesa sdk. This method call will start an activity for result that will show the M-Pesa payment Ui to process the payment and send a result back when it is done.

The pay method can be called from a Fragment or an Activity and it takes as parameters the request code used for the startActivityForResult call, the amount to be processed and a transaction reference of the payment.

The transaction reference will uniquely identify the product or service being paid.

Make the payment call

MpesaSdk.pay(activity = this,requestCode = 1, amount = "1", transactionReference = "T12335C")

Handle the result

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)
    when(requestCode) {
         1 -> {
              when(resultCode) {
                   Activity.RESULT_OK -> {
                        val transactionId = data?.extras.getString(MpesaSdk.ARG_RESULT_TRANSACTION_ID)
                        val conversationId = data?.extras.getString(MpesaSdk.ARG_RESULT_CONVERSATION_ID)
                        //Do Something
                   }
                   Activity.RESULT_CANCELED -> {
                        //Do Something
                   }
              }
         }
    }
}
