MIT

README

Lightweight PHP SDK for integrating with the EvPay MNO Payment Gateway. Supports payment requests, reconciliation, and callback handling.

🚀 Installation

Install via Composer:

composer require salymmbise/evpay

⚙️ Requirements

• PHP 8.1+
• Composer

📦 Basic Usage

1. Initialize Client

require 'vendor/autoload.php';

use EvMak\Client;

$client = new Client(
    "https://your-evmak-api-url.com",
    "your-username"
);

2. Send Payment Request

use EvMak\Payment;

$payment = new Payment($client);

$response = $payment->request([
    "api_source" => "WEBHOSTTZ",
    "api_to" => "TigoPesa", // Mpesa, AirtelMoney, HaloPesa
    "amount" => 1000,
    "product" => "TestPayment",
    "callback" => "https://yourdomain.com/callback",
    "mobileNo" => "255686668866",
    "reference" => uniqid("EVM")
]);

print_r($response);

3. Check Transaction (Reconciliation)

use EvMak\Reconciliation;

$recon = new Reconciliation($client);

$status = $recon->check("EVM123456");

print_r($status);

🔐 Callback Handling

Your system must handle payment confirmation from EvMak.

Example (Laravel)

Route::post('/callback', function (\Illuminate\Http\Request $request) {

    $data = $request->all();

    // Validate and store transaction
    // Recommended: verify hash and reference

    return response()->json([
        "Status" => "Success"
    ]);
});

🔑 Hash Generation

The API uses MD5 hashing:

md5(username . '|' . date('d-m-Y'));

This is handled automatically by the SDK.

📱 Supported Networks

• Mpesa
• TigoPesa
• AirtelMoney
• HaloPesa

⚠️ Best Practices

• Always store transactions before sending requests
• Use unique references (uniqid() or UUID)
• Secure your callback endpoint
• Log all API responses
• Implement retries for failed requests

🧪 Testing

Use sandbox/test endpoint provided by EvMak before going live.

❗ Error Handling

Typical response codes:

Code	Meaning
200	Success
403	Authentication failed
404	Wrong destination
500	Server error
