Laravel Mpesa Multivendor Package by Akika Digital

This Laravel package provides convenient methods for integrating Mpesa Daraja API's functionalities into your Laravel application. The package will allow using more than one shortcodes. It also includes the recent Tax Remmitance and Bill Manager APIs.

Installation

You can install the package via composer:

composer require akika/laravel-mpesa-multivendor

After installing the package, publish the configuration file using the following command:

php artisan mpesa-multivendor:install

This will generate a mpesa.php file in your config directory where you can set your Mpesa credentials and other configuration options.

.env file Setup

Add the following configurations into the .env file

MPESA_ENV=
MPESA_DEBUG_MODE=

The value is either production or sandbox

NOTE: The mpesa.php config file sets the default MPESA_ENV value to sandbox. This will always load sandbox urls.

Function Responses

All responses, except the token generation response, conform to the responses documented on the daraja portal.

Usage

Initializing Mpesa

use Akika\LaravelMpesaMultivendor\Mpesa;

$mpesa = new Mpesa($mpesaShortCode, $consumerKey, $consumerSecret, $apiUsername, $apiPassword, $passKey = null);

• $mpesaShortcode: The shortcode to use for the current operation
• $consumerKey: Obtained from Daraja portal
• $consumerSecret: Obtained from Daraja portal
• $apiUsername: Mpesa portal API user's username

Daraja utilizes the two main urls for callbacks. Timeout Url and Result Url. The two urls will also be used in this package as follows:

Fetching Token

You can fetch the token required for Mpesa API calls as follows:

$token = $mpesa->getToken();

You can fetch mpesa account balance as follows:

$balance = $mpesa->getBalance($resultUrl, $timeoutUrl);
