Webhookovi

Događaji

Pretplatite se objavom channels.webhooks[] u konfiguraciji svog web shopa (id, url i events). URL mora biti javni https; privatne, loopback i interne adrese odbijaju se pri spremanju konfiguracije i ponovno pri slanju.

Tijelo

Tijelo je kanonski JSON (RFC 8785) i bajt po bajt jednako pri svakom pokušaju. data.order je cjeloviti potpisani dokument order.v1; data.fromStatus postoji samo u order.status_changed.

{
  "createdAt": "2026-10-19T09:30:00.000Z",
  "data": {
    "fromStatus": "received",
    "order": {
      "…": "order.v1"
    },
    "orderId": "<order id>",
    "status": "confirmed"
  },
  "id": "<event id>",
  "schemaVersion": 1,
  "tenantId": "<tenant id>",
  "type": "order.status_changed"
}

Zaglavlja

Svaka isporuka nosi pet zaglavlja. Uklanjajte duplikate prema CutOptim-Event-Id: ponovni pokušaj i ponovna isporuka ponavljaju ga, dok se CutOptim-Delivery-Id razlikuje.

Provjera potpisa

Potpis je t=<unix seconds>,v1=<hex HMAC-SHA256(secret, "<t>.<raw body>")>. Prihvatite isporuku kad bilo koja vrijednost v1 odgovara jednoj od vaših tajni, a t je unutar 300 sekundi od vašeg sata; uspoređujte u konstantnom vremenu. Provjerite sirove bajtove prije parsiranja: okvir koji tijelo parsira i ponovno serijalizira mijenja ga i svaka provjera pada.

Dva prijamnika ispod referentni su primjeri, nepromijenjeni: Node 18+ samo s node:crypto i PHP 7.4+ bez Composera. Oba čitaju tajnu iz CUTOPTIM_WEBHOOK_SIGNING.

Ponovni pokušaji, neisporučene poruke i ponovna isporuka

Odgovor koji nije 2xx, istek vremena i preusmjeravanje neuspjeli su pokušaji. Isporuka se pokušava ukupno 6 puta, s rastućim razmacima; nakon zadnjeg neuspjeha postaje neisporučena poruka. URL koji se razrješava u privatnu adresu odmah je neisporučena poruka. Vaš poslužitelj može pročitati zapisnik isporuka i tražiti ponovnu isporuku tajnim ključem (/cfg/v1/admin/deliveries); ponovna isporuka zadržava id događaja.

Testne narudžbe

Narudžba zaprimljena s testnim ključem ne stavlja u red nikakav webhook ni e-poštu: vaš ERP i vaši kupci nikad ne vide testni promet.
