MTN MoMo API

This package helps you integrate the MTN MOMO API into your Php or Laravel application. Its wrapper around the MTN Open API to provide you with a much simpler API to work with.

Installation

You are required to have PHP 7.0 or later. You can install the package via composer:

composer require patricpoba/mtn-momo-api-php

Usage

In production, the needed credentials are provided for you on the MTN OVA management dashboard after KYC requirements are met. But in a testing environment, a sanbox user would have to be created by you using the API, which this package can do for you.

Creating a sandbox environment API user

We need to get the User ID and User Secret and to do this we shall need to use the Primary Key for the Product to which we are subscribed, as well as specify a host. The library ships with a commandline application that helps to create sandbox credentials. It assumes you have created an account on https://momodeveloper.mtn.com and have your Ocp-Apim-Subscription-Key (primaryKey) located at https://momodeveloper.mtn.com/developer.

## On the command line, at the root of your project, run 
$ php ./vendor/patricpoba/mtn-momo-api-php/src/SandboxUserProvision.php -k '9cc70894a5d24dba8a8a50fcecbc0568' -c 'https://yourdomain.com'

The option c is your callback host and the option k is the primary key or Ocp-Apim-Subscription-Key for the specific product to which you are subscribed. The API Key is unique to the product and you will need an API Key for each product you use. You should get a response similar to the following:

Your Sandbox credentials :
Ocp-Apim-Subscription-Key: f1d075127844476fa3c4636593e60cf8
UserId (X-Reference-Id)  : 89ce5960-3f68-4da4-bd69-0584073870b8
ApiKey (ApiSecret)       : 46b9302a8ae444c8a7a956bb4c7f2c05
Callback host            : https://yourdomain.com

Configuration

We have to setup up the package to utilise the our momodeveloper credentials by creating an instance of the MtnConfig and pass it to the constructor of the class of the product (collection, disbursement or remittance) we want to use as demonstrated below. The configuration can be overriden a product instance by calling the ->setConfig($config) method and passing the new config instance.

use PatricPoba\MtnMomo\MtnConfig;

 
$config = new MtnConfig([ 
    // mandatory credentials
    'baseUrl'               => 'https://sandbox.momodeveloper.mtn.com', 
    'currency'              => 'EUR', 
    'targetEnvironment'     => 'sandbox', 

    // product specific blocks
    "collectionApiSecret"   => '3463953c31064e6e8ae634cd94f13c8c', 
    "collectionPrimaryKey"  => 'aadb6f286e95415db9024c7a4e2c6025', 
    "collectionUserId"      => 'b4d4019f-8617-4843-a4b8-ed90941747a3',
 
    "disbursementApiSecret" => '3463953c31064e6e8ae634cd94f13c8c',

Collection

Collections is used for requesting a payment from a customer (Payer) and checking status of transactions. Read more on Momo Collection

collectionPrimaryKey: Primary Key for the Collection product on the developer portal.
collectionUserId : For development environment, use the sandbox credentials else use the one on the developer portal.
collectionApiSecret : For development environment, use the sandbox credentials else use the one on the developer portal.

use PatricPoba\MtnMomo\MtnConfig;

 
$config = new MtnConfig([

$params = [
    "mobileNumber"      => '233540000000',

    "payeeNote"         => '1212'
];

$transactionId = $collection->requestToPay($params);

$transaction = $collection->getTransaction($transactionId);

Collection Methods

requestToPay: This operation is used to request a payment from a consumer (Payer). The payer will be asked to authorize the payment. The transaction is executed once the payer has authorized the payment. The transaction will be in status PENDING until it is authorized or declined by the payer or it is timed out by the system. Status of the transaction can be validated by checking the status field on the result of getTransaction() method.

   $transactionId = $collection->requestToPay($params);

getTransaction: Retrieve transaction information using the transactionId returned by requestToPay. You can invoke it at intervals until the transaction fails or succeeds.

   $transaction = $collection->getTransaction($transactionId);

getBalance: Get the balance of the account.

   $transaction = $collection->getBalance();

accountHolderActive: check if an account holder is registered and active in the system.

   $transaction = $collection->accountHolderActive($mobileNumber);

Disbursement

Disbursement is used for transferring money from the provider account to a customer. Read more on Momo Disbursement
