MakePay PHP SDK

Overview

The MakePay PHP SDK is a lightweight Composer library for server-side MakePay integrations. It wraps API-key authentication, payment-link operations, MakePay settings, and signed webhook verification.

Public source repository:

https://github.com/CHASH-HOSTING/makepay-php-sdk

Installation

Install with Composer through the public Git repository:

{
  "repositories": [
    {
      "type": "vcs",
      "url": "https://github.com/CHASH-HOSTING/makepay-php-sdk"
    }
  ],
  "require": {
    "makepay/makepay-php": "^0.1"
  }
}

Then run:

composer update makepay/makepay-php

Authentication

Create a MakePay API key from the MakeCrypto merchant developer area and keep the secret in server-side environment variables only.

use MakePay\Client;

$makepay = new Client([
    'keyId' => getenv('MAKEPAY_KEY_ID'),
    'keySecret' => getenv('MAKEPAY_KEY_SECRET'),
    // Optional: override only when MakePay gives you a custom checkout origin.
    'checkoutBaseUrl' => 'https://makepay.io',
]);

The SDK sends X-MakeCrypto-Key-Id and X-MakeCrypto-Key-Secret headers to the MakePay partner API.

Create Payment Link

$response = $makepay->createPaymentLink([
    'title' => 'Order #1042',
    'description' => 'Checkout for order #1042',
    'amount' => '129.99',
    'currency' => 'USDT',
    'orderId' => 'order_1042',
    'customerEmail' => 'buyer@example.com',
    'returnUrl' => 'https://merchant.example/orders/1042',
    'successUrl' => 'https://merchant.example/orders/1042/success',
    'failureUrl' => 'https://merchant.example/orders/1042/pay',
    'expirationTime' => '12h',
]);

header('Location: ' . $response['paymentLink']['publicUrl']);

Pass sendPaymentRequestEmail when you want MakePay to email the customer as part of creation:

$makepay->createPaymentLink($payload, [
    'sendPaymentRequestEmail' => true,
]);

Embedded Checkout

PHP backends can generate hosted links, embedded iframe URLs, and HTML snippets after creating a payment link.

$paymentUid = $response['paymentLink']['uid'];

$hostedUrl = $makepay->hostedCheckoutUrl($paymentUid);
$embedUrl = $makepay->embeddedCheckoutUrl($paymentUid, [
    'parentOrigin' => 'https://merchant.example',
]);

echo $makepay->embedButtonHtml($paymentUid, [
    'buttonLabel' => 'Pay with crypto',
]);

echo $makepay->iframeHtml($paymentUid, [
    'iframeTitle' => 'Secure MakePay checkout',
]);

Use a hosted link fallback beside every iframe so shoppers can continue if the browser, CMS, or store theme blocks embedded payment pages.

Read And Update Links

$links = $makepay->listPaymentLinks();
$detail = $makepay->getPaymentLink('PAYMENT_LINK_UID');

$makepay->updatePaymentLink('PAYMENT_LINK_UID', [
    'status' => 'paused',
]);

$makepay->sendPaymentRequestEmail(
    'PAYMENT_LINK_UID',
    'buyer@example.com'
);

Settings

$settings = $makepay->getSettings();

$makepay->updateSettings([
    'callbackUrl' => 'https://merchant.example/webhooks/makepay',
]);

Webhook Verification

MakePay signs the exact raw request body. Read php://input before parsing JSON.

use MakePay\Webhook;

$rawBody = file_get_contents('php://input');
$signature = $_SERVER['HTTP_X_MAKEPAY_SIGNATURE'] ?? null;

$event = Webhook::parse(
    $rawBody,
    $signature,
    getenv('MAKEPAY_WEBHOOK_SECRET')
);

if (($event['event']['type'] ?? '') === 'status_changed') {
    // Update the local order.
}

http_response_code(200);
echo 'ok';

Error Handling

API errors throw MakePay\MakePayException. The exception includes the HTTP status code and decoded response body.

use MakePay\MakePayException;

try {
    $makepay->getPaymentLink('PAYMENT_LINK_UID');
} catch (MakePayException $error) {
    error_log($error->getMessage());
    error_log((string) $error->getStatusCode());
}

Source Layout

The canonical monorepo source lives in apps/plugins/php-sdk. The public repository mirrors only the SDK files so developers can install or inspect it without the full MakeCrypto workspace.
