# Webhookat

Pollinga sadje, atte vuojáhat `webhook_url`-dávvala. Go jearaldat olaha loahpalaš dili (`succeeded`, `failed` dahje
`canceled`), sáddet mii vuolláičállojuvvon `POST`-jearaldaga dan čujuhussii.

```bash
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": "..."}'
```

> [!NOTE]
> Čujuhus ferte leat almmolaš `https://`. Priváhta, báikkálaš ja eai-HTTPS-čujuhusat hilgojuvvojit
> `422 invalid_webhook_url`-dain ovdal go mihkkege máksojuvvo.

## Dáhpáhus

```http Jearaldaga oaivilčállagat
POST /hooks/doitong HTTP/1.1
Content-Type: application/json
User-Agent: Doitong-Webhooks/1
Doitong-Request-Id: req_8k2m4q7x1z9c3v5b6n0p2r4t
Doitong-Signature: t=1760961609,v1=5f1c0d6e2b…
```

```json Jearaldaga čoahkkáigeassu
{
  "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` lea `request.succeeded`, `request.failed` dahje `request.canceled`.
- `data` lea olles jearaldat-objekta, juste dat maid `GET /requests/{id}` máhca.
- `id` lea dásset jearaldahkii ja dan loahpalaš dillái. Geavat dan jávkadit sáddema maid leat juo gieđahallan.

## Sáddemat ja ođđasisgeahččamat

Vástid 10 sekunda siste juohke `2xx`-diliin. Buot eará (dahje áigemearri) geahččaluvvo ođđasit: oktiibuot gitta 6 geahččaleami,
30 sekunda, 2 minuhta, 10 minuhta, 1 diimmu ja 6 diimmu maŋŋá. Dahjegeavahusa barggu maŋŋá go leat vástidan, ii ovdal.

## Dárkkis vuolláičállosa

Juohke čoavddas lea iežas vuolláičájehančiegus. Loga dan oktii `GET https://api.doitong.com/v1/account`-bokte (`webhook_signing_secret`,
ja dat álgá `whsec_`-ain) ja vurke dan čoavdda lahka.

`Doitong-Signature`-oaivilčállagis lea `t=<unix time>,v1=<signature>`, gos vuolláičálus lea heksadessi HMAC-SHA256
`"<t>.<raw request body>"`-as, mas du čiegus lea čoavddan. Dárkkisteapmái:

1. Váldde ávdnasčoahkkáigeasu bádnosa juste nu go dat bođii (ovdal JSON-parsena).
2. Geavat HMAC-SHA256 `t + "." + body`-s du čiegusain, unnimus bustávaid heksadessii.
3. Buohtastahtti dan `v1`-in dássetáigásaš vugiin.
4. Hilggo dáhpáhusa go `t` lea eanet go 5 minuhta eret du diimmus (ođđasis sáddema vuostá suodjaleapmi).

Olles vuostáiváldi Node.js (Express) ja Python (Flask):

```javascript Node.js · Express
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);
});

    parts = dict(p.split("=", 1) for p in request.headers.get("Doitong-Signature", "").split(",") if "=" in p)
    t = parts.get("t", "0")
    expected = hmac.new(SECRET, t.encode() + b"." + body, hashlib.sha256).hexdigest()
    if not hmac.compare_digest(expected, parts.get("v1", "")) or abs(time.time() - int(t)) > 300:

    event = json.loads(body)
    if event["type"] == "request.succeeded":
        print(event["data"]["id"], [o["url"] for o in event["data"]["outputs"]])
    return "", 204
```
