2. Payment Confirmation

• Method POST
• Headers: Signature
• Body: Invoice with payment status
• Signature Validation: Incoming webhook request has a header that can be used to verify the payload. The name of the header containing the signature can be configured in the ‘Signature’ header key to validate signatures.
• This is an example of how you will compute the signature in PHP:
  Copy

  // Secret key can be found in your profile information
  $secret = "API_SECRET";
  // Get incoming webhook request body content
  $body_content = file_get_contents("php://input");
  //
  $computed_signature = hash_hmac('sha256', $body_content, $secret);
  // Get signature from header
  $signature = getallheaders()["Signature"];
  // Check computed signature
  $validated = hash_equals($computed_signature, $signature); // : bool
  
  if ($validated) {
      $payment = json_decode($body_content, true);
      //@Todo: check invoice status first ($payment["invoice"]["status"] === 'paid')
      if ($payment["invoice"]["status"] === 'paid') {
          //@Todo: confirm order
      } elseif ($payment["invoice"]["status"] === 'failed') {
          //@Todo: do anything when payment failed
      }
  }
  exit;
