API & webhook docs

Authentication

Create a key in Dashboard → API keys. Send it as a Bearer token. Each key only ever sees its own shop. Limit: 120 requests/minute per key (HTTP 429 beyond). Money is always an integer in minor units (cents) plus a currency code.

curl https://www.sellpass.net/api/v1/ping \
  -H "Authorization: Bearer sk_live_…" \
  -H "Accept: application/json"

Errors use standard HTTP codes with {"message": "…", "errors": {…}}. Lists return {"data": [...], "meta": {current_page, last_page, per_page, total}}.

Webhooks

Add endpoints in Dashboard → Webhooks. We POST JSON and retry failed deliveries (non-2xx or timeout after 10 s) up to 5 times: after 1 min, 5 min, 30 min, 2 h and 6 h. Every attempt is logged with the response so you can debug and resend.

order:createdorder:paidorder:partialorder:completedorder:cancelledorder:refundedorder:disputedorder:on_holdproduct:stock_lowquery:createdquery:repliedfeedback:receivedsubscription:createdsubscription:renewedsubscription:cancelled

POST https://your-server/hook
X-Signature: 3f1c…   (hex HMAC-SHA512 of the raw body, keyed with your webhook secret)
X-Event: order:paid
X-Delivery-Id: evt_…

{"id":"evt_…","event":"order:paid","created_at":"2026-01-01T12:00:00+00:00",
 "data":{"uuid":"…","status":"completed","customer_email":"buyer@example.com","total":1299,"currency":"USD","items":[…]}}

Verify the signature (PHP)

$raw = file_get_contents('php://input');
$expected = hash_hmac('sha512', $raw, getenv('WEBHOOK_SECRET'));
if (! hash_equals($expected, $_SERVER['HTTP_X_SIGNATURE'] ?? '')) {
    http_response_code(401); exit;
}
$event = json_decode($raw, true);   // dedupe on $event['id']

Node.js

const crypto = require('crypto');
const expected = crypto.createHmac('sha512', process.env.WEBHOOK_SECRET).update(rawBody).digest('hex');
const ok = crypto.timingSafeEqual(Buffer.from(expected), Buffer.from(req.get('X-Signature') || ''));

Dynamic products

For products generated on demand (license servers, account creation). After payment we POST the order to your URL; the response body (≤64 KB, within 10 s) is delivered to the buyer. The request is signed exactly like webhooks with the product's signing secret. Only public addresses are allowed; redirects are not followed. If your server fails, the order stays "paid · to fulfil" and you can deliver manually.

{"event":"order:paid","invoice":"…","product_id":12,"variant_id":null,"quantity":1,
 "customer_email":"buyer@example.com","custom_fields":{"Username":"neo"},"total":999,"currency":"USD"}
