API Reference

#Overview

All endpoints accept GET or POST with form-encoded parameters and return JSON. The base URLs are:

Every request is charged against your prepaid balance. Orders are debited atomically — parallel requests can never spend more than your balance.

#Authentication

Pass your API key as the key parameter on every request. Keys are issued per account and control access to that account's balance and orders only. Keep them secret — anyone holding your key can place orders on your balance.

Keys can be regenerated any time from your profile — old keys stop working immediately.

#Rate limits

When a limit is exceeded the API responds with HTTP 429 Too Many Requests and a JSON error message. Slow down and retry after a minute.

#Errors

Failures return HTTP 200 with an error body (compatible with the standard SMM API), except for rate limiting which uses HTTP 429.

#Webhooks

Webhooks push order status changes to your server instead of you polling. Set your webhook URL in your profile; we sign every payload with an HMAC so you can verify it came from us.

Webhooks are currently enabled on this panel.

COPY{
  "event": "order.status",
  "order": 32,
  "status": "completed",
  "remains": 0,
  "charge": "1.2600"
}

COPY$payload = file_get_contents("php://input");
$signature = $_SERVER["HTTP_X_SMMIZE_SIGNATURE"] ?? "";
$expected = hash_hmac("sha256", $payload, YOUR_WEBHOOK_SECRET);
if (!hash_equals($expected, $signature)) { http_response_code(401); exit; }
// payload is verified — process the order update

Failed deliveries are retried automatically. Always verify the signature before acting on a payload.
