Binance Pay License – API Documentation

What is a License Key?

Your license key is a unique identifier that links your account to a specific plan. When you embed this key into your script, our API will return the Binance credentials (API key, secret, email or id, etc.) associated with that plan, allowing your customers to send payments via Binance Pay and have them verified automatically.

Prerequisite: You must have an active plan and have configured Binance credentials for that plan in your dashboard.

API Endpoints

All API calls must be made over HTTPS. The base URL for all endpoints is:

https://panel.smmpanelbdlab.com

Integration Examples

Below are examples showing how to fetch credentials and verify payments using your license key. Click the Copy button on any code block to copy the code.

PHP (cURL)

/* Step 1: Get Binance credentials */
$license_key = 'YOUR_LICENSE_KEY';
$api_url = 'https://panel.smmpanelbdlab.com/api/verify-license?license=' . urlencode($license_key);
$ch = curl_init();
curl_setopt_array($ch, [
    CURLOPT_URL => $api_url,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_SSL_VERIFYPEER => true,
]);
$response = curl_exec($ch);
curl_close($ch);
$data = json_decode($response, true);

if (!$data['success']) {
    die('License error: ' . $data['message']);
}
/* Use $data['data'] for Binance credentials */

/* Step 2: Show the payment modal (popup) – no redirect needed */
/* Your script should open a modal with Binance ID, QR, amount, etc. */
                

PHP – Full HTML Payment Modal

Installation Instructions

WooCommerce: Upload the ZIP via Plugins → Add New → Upload Plugin.
SMM Script: Extract the files into your SMM script’s module folder and enable the payment method.
API Library: Include the PHP file and follow the integration examples above.

All modules are open‑source and require a valid license key to operate.

How to Add the Module to Your Website

Adding Binance Pay auto‑verification to your SMM script or any PHP website is straightforward. Follow these steps:

Purchase a plan from your dashboard and obtain a license key.
Configure Binance credentials for that plan (API key, secret, email/ID, QR code, currency).
Embed the license key in your website’s admin panel.
Write a small integration using one of the examples above:
- Fetch credentials using the license key when a user initiates a payment.
- Display the payment details (Binance ID, QR, amount) in a modal/popup on your site.
- After the user sends the payment, ask for the Order ID and call /api/verify-payment to confirm.
That’s it – your customers will now see the Binance Pay modal and payments will be verified automatically.

Important: Your callback URL (if you use one) must be publicly accessible and should expect POST parameters: payment_id, order_id, status, and message.

Error Codes & Common Issues

Error Message	Likely Cause	Solution
`Invalid or expired license key`	Incorrect or deactivated key	Check dashboard for correct key
`Plan expired or inactive`	Plan has expired	Renew your plan
`Binance credentials not configured`	API keys missing	Add Binance credentials in plan settings
`Order ID already used`	Duplicate Order ID	Use a unique Order ID
`Amount mismatch`	Amount doesn't match	Double‑check the amount
`Order ID too old`	Transaction is older than time limit	Use a recent transaction

Testing

You can test your integration by making a small payment using the Binance Pay sandbox or a real wallet. The API will return success: true only if the Order ID is valid and matches all criteria.

If you encounter issues, check your Binance API credentials and ensure your server can connect to the Binance API (port 443).
