mpesa-node-api

M-Pesa Node API

Node.js wrapper for the M-Pesa Mozambique API.

Using the API

1. Install it using npm:

   npm install mpesa-node-api
   

2. Create the configuration .env file on your root directory based on .env.example.

3. Use your favorite text editor to edit the .env file and fill in the blank lines with configuration you got from the M-Pesa Developer Portal. See an example:

   MPESA_PUBLIC_KEY=example_public_key
   MPESA_API_HOST=api.sandbox.vm.co.mz
   MPESA_API_KEY=example_api_key
   MPESA_ORIGIN=developer.mpesa.vm.co.mz
   MPESA_SERVICE_PROVIDER_CODE=171717
   

4. In your JavaScript file, import the package using require():

   const mpesa = require('mpesa-node-api');
   

Supported Transactions

All transactions return a Promise. So you can either use then/catch or async/await to get the transaction response.

Responses match the ones specified on the M-Pesa API Documentation.

Example C2B response:

{
  "output_ConversationID": "f02f957c19f4499faf6a6f19c0307e69",
  "output_ResponseCode": "INS-0",
  "output_ResponseDesc": "Request processed successfully",
  "output_ThirdPartyReference": "ZXVM9H",
  "output_TransactionID": "f449abol7j38"
}

Customer to Business (C2B)

const mpesa = require('mpesa-node-api');

mpesa.initiate_c2b(/* amount */ 10, /* msisdn */ 258843330333, /* transaction ref */ 'T12344C', /*3rd party ref*/ 'ref1')
    .then(function(response) {
      // logging the response
      console.log(response);
    })
    .catch(function(error) {
      // TODO: handle errors
    });

Business to Customer (B2C)

const mpesa = require('mpesa-node-api');

mpesa.initiate_b2c(/* amount */ 10, /* msisdn */ 258843330333, /* transaction ref */ 'T12344C', /*3rd party ref*/ 'ref1')
    .then(function(response) {
      // logging the response
      console.log(response);
    })
    .catch(function(error) {
      // TODO: handle errors
    });

Planned Support:

• B2B
• Reversal
• Query Transaction Status

Using custom configuration

Optionally, you can also use custom configuration to initialize the API:

const mpesa = require('mpesa-node-api');

mpesa.initializeApi({
    baseUrl: "YOUR_MPESA_API_HOST",
    apiKey: "YOUR_MPESA_API_KEY",
    publicKey: "YOUR_MPESA_PUBLIC_KEY",
    origin: "YOUR_MPESA_ORIGIN",
    serviceProviderCode: "YOUR_MPESA_SERVICE_PROVIDER_CODE"
});
mpesa.initiate_c2b( 10, 258843330333, 'T12344C', 'ref1');
