Payment Gateway API

Integrate ShobarBondhu seamless payment gateway into your website or application.

Welcome to the official API documentation. Our API allows merchants to create payment requests and receive instant callbacks when a customer successfully completes a payment using their account balance.

Authentication

All API requests require authentication. You must include your api-key and api-secret in the HTTP Headers of every request. You can generate these keys from your Merchant Dashboard.

Create Payment

Initialize a new payment request. This will return a secure payment URL where you need to redirect your customer to complete the transaction.

$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_URL => 'https://shobarbondhu.com/api/create-payment',
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_CUSTOMREQUEST => 'POST',
  CURLOPT_POSTFIELDS => json_encode([
    "amount" => 500,
    "callback_url" => "https://your-website.com/success"
  ]),
  CURLOPT_HTTPHEADER => array(
    'api-key: YOUR_API_KEY',
    'api-secret: YOUR_API_SECRET',
    'Content-Type: application/json'
  ),
));

$response = curl_exec($curl);
curl_close($curl);
echo $response;

{
    "success": true,
    "invoice_id": "INV168452ABCDEF",
    "payment_url": "https://shobarbondhu.com/payment-gateway/checkout/INV168452ABCDEF"
}

Payment Callback

Once the customer successfully enters their OTP and PIN on our secure gateway, their account balance is deducted, and the funds are instantly added to your merchant balance.

After this process, we redirect the customer back to the callback_url you provided during the "Create Payment" request.
