Webhook

Ara bħala Markdown Aġġornat

Minflok tagħmel polling, agħti webhook_url lil run. Meta t-talba tasal għal status finali (succeeded, failed jew canceled), nibagħtu POST iffirmat lil dak l-URL.

terminal
curl -X POST "https://api.doitong.com/v1/run/{model_id}?webhook_url=https://example.com/hooks/doitong" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"prompt": "..."}'

L-avveniment

Headers tat-talba
POST /hooks/doitong HTTP/1.1
Content-Type: application/json
User-Agent: Doitong-Webhooks/1
Doitong-Request-Id: req_8k2m4q7x1z9c3v5b6n0p2r4t

Body tat-talba
{
  "id": "evt_8k2m4q7x1z9c3v5b6n0p2r4t_succeeded",
  "object": "event",
  "type": "request.succeeded",
  "created_at": "2026-10-20T12:00:09Z",
  "data": {
    "id": "req_8k2m4q7x1z9c3v5b6n0p2r4t",
    "object": "request",
    "status": "succeeded",
    "outputs": [ { "type": "video", "url": "https://content.doitong.com/dev-api/…/0-output.mp4" } ]
  }
}
  • type huwa request.succeeded, request.failed jew request.canceled.
  • data huwa l-oġġett sħiħ tat-talba, eżattament dak li jirritorna GET /requests/{id}.
  • id huwa stabbli għal talba u għall-istatus finali tagħha. Użah biex tinjora kunsinna li diġà pproċessajt.

Kunsinni u tentattivi mill-ġdid

Irrispondi bi kwalunkwe status 2xx fi żmien 10 sekondi. Kull ħaġa oħra (jew timeout) terġa’ tiġi ppruvata: sa 6 tentattivi b’kollox, wara 30 sekonda, 2 minuti, 10 minuti, siegħa u 6 sigħat. Agħmel ix-xogħol bil-mod wara li tirrispondi, mhux qabel.

Ivverifika l-firma

Kull ċavetta għandha sigriet tal-iffirmar tagħha. Aqrah darba minn GET https://api.doitong.com/v1/account (webhook_signing_secret, jibda b’whsec_) u aħżnu ħdejn iċ-ċavetta.

Il-header Doitong-Signature huwa t=<unix time>,v1=<signature>, fejn il-firma hija l- HMAC-SHA256 hex ta’ "<t>.<raw request body>" bis-sigriet tiegħek bħala ċ-ċavetta. Biex tivverifika:

  1. Ħu l-bytes tal-body mhux ipproċessat eżattament kif waslu (qabel kwalunkwe parsing ta’ JSON).
  2. Ikkalkula HMAC-SHA256 ta’ t + "." + body bis-sigriet tiegħek, bħala hex b’ittri żgħar.
  3. Qabblu ma’ v1 f’ħin kostanti.
  4. Irrifjuta l-avveniment meta t ikun aktar minn 5 minuti ’l bogħod mill-arloġġ tiegħek (protezzjoni kontra replay).

Riċevitur sħiħ f’Node.js (Express) u Python (Flask):

import crypto from "node:crypto";
import express from "express";

const SECRET = process.env.DOITONG_WEBHOOK_SECRET; // whsec_...
const app = express();

app.post("/hooks/doitong", express.raw({ type: "application/json" }), (req, res) => {
  const header = req.get("Doitong-Signature") || "";
  const parts = Object.fromEntries(header.split(",").map((p) => p.split("=", 2)));
  const t = Number(parts.t);
  const expected = crypto.createHmac("sha256", SECRET).update(t + "." + req.body).digest("hex");
  const given = Buffer.from(parts.v1 || "", "utf8");
  const valid =
    given.length === expected.length &&
    crypto.timingSafeEqual(given, Buffer.from(expected, "utf8")) &&
    Math.abs(Date.now() / 1000 - t) < 300;
  if (!valid) return res.status(400).send("bad signature");

  const event = JSON.parse(req.body);
  if (event.type === "request.succeeded") {
    console.log(event.data.id, event.data.outputs.map((o) => o.url));
  }
  res.sendStatus(204);
});

Suġġerimenti

  • Irrispondi malajr u poġġi l-ipproċessar tiegħek fil-kju.
  • Is-sigriet jappartjeni għall-API key li bdiet ir-run. Ċwievet f’servizzi differenti għandhom sigrieti differenti.
