mpesa_sdk_dart

Dart package for M-Pesa API (Mozambique)

Ready Methods/APIs

• C2B
• B2B
• B2C
• TRANSACTION STATUS
• REVERSAL

Requisites

We highly recommend reading Mpesa API docs first!

You Will need a few things from there before development.

1. Api Key
2. Public Key

• Login or Register as a M-Pesa developer here if you haven't.
• You will be issued with an API Key and a Public Key. You will use these to generate your access token.

Usage

Add dependency in pubspec.yaml

dependencies:
  mpesa_sdk_dart: <latest_version>

Import in your Flutter app or plain dart app.

import 'package:mpesa_sdk_dart/mpesa_sdk_dart.dart';

Generate a token

String token = MpesaConfig.getBearerToken(
    'API_KEY_HERE',
    'PUBLIC_KEY_HERE',
  );

C2B Api Call

Initialize your payload

PaymentRequest payload = PaymentRequest(
    inputTransactionReference: 'inputTransactionReference',
    inputCustomerMsisdn: '25884xxxxxxx',
    inputAmount: inputAmount,
    inputThirdPartyReference: 'inputThirdPartyReference',
    inputServiceProviderCode: 'inputServiceProviderCode',
  );

Perform the api call

MpesaTransaction.c2b(token, apiHost, payload);

B2C Api Call

Initialize your payload

PaymentRequest payload = PaymentRequest(
    inputTransactionReference: 'inputTransactionReference',
    inputCustomerMsisdn: '25884xxxxxxx',
    inputAmount: inputAmount,
    inputThirdPartyReference: 'inputThirdPartyReference',
    inputServiceProviderCode: 'inputServiceProviderCode',
  );

Perform the api call

MpesaTransaction.b2c(token, apiHost, payload);

Reversal Api Call

Initialize your payload

ReversalRequest payload = ReversalRequest(
    inputTransactionID: 'input_TransactionID',
    inputSecurityCredential: 'input_SecurityCredential',
    inputInitiatorIdentifier: 'input_InitiatorIdentifier',
    inputThirdPartyReference: 'input_ThirdPartyReference',
    inputServiceProviderCode: 'input_ServiceProviderCode',
    inputReversalAmount: montant, // Optional
  );

Perform the api call

MpesaTransaction.reversal(token, apiHost, payload);

B2B Api Call

Initialize your payload

TransferRequest payload = TransferRequest(
    inputTransactionReference: 'input_TransactionReference',
    inputAmount: inputAmount,
    inputThirdPartyReference: 'input_ThirdPartyReference',
    inputPrimaryPartyCode: 'input_PrimaryPartyCode',
    inputReceiverPartyCode: 'input_ReceiverPartyCode',
  );

Perform the api call

MpesaTransaction.b2b(token, apiHost, payload);

Query Transaction Status Api Call

Perform the api call

MpesaTransaction.getTransactionStatus(
    token,
    apiHost,
    'input_ThirdPartyReference',
    'input_QueryReference',
    'input_ServiceProviderCode',
  );

Handle Response

All transaction methods returned an http response. So what you have to do is assign your call to a property of type Response (From http package). Note that this is an async task.

Response response = await MpesaTransaction.c2b(token, apiHost, payload);
print(response.body);

if(response.statusCode == 201) {  // if is resource created!
  // Do something!
}
