Webhook

Mussar sco Markdown Actualisà

Empè da far polling, dat a l'execuziun in webhook_url. Cur che la dumonda cuntanscha in status final (succeeded, failed u canceled), tramettain nus in POST signà a quest 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" \

L'event

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

  }
}
  • type è request.succeeded, request.failed u request.canceled.
  • data è l'entir object da la dumonda, exactamain quai che GET /requests/{id} returnescha.
  • id è stabil per ina dumonda e ses status final. Utilisescha el per ignorar ina tramisiun gia elavurada.

Tramisiuns e repetiziuns

Respunda cun in status 2xx entaifer 10 secundas. Tut auter (u in timeout) vegn repetì: fin a 6 emprovas en total, suenter 30 secundas, 2 minutas, 10 minutas, 1 ura e 6 uras. Fa il lavur lent suenter tia resposta, betg avant.

Verifitgar la signatura

Mintga clav ha ses agen secret da signatura. Legia el ina giada da GET https://api.doitong.com/v1/account (webhook_signing_secret, el cumenza cun whsec_) e memorisescha el sper la clav.

Il header Doitong-Signature è t=<unix time>,v1=<signature>, nua che la signatura è il HMAC-SHA256 hexadecimal da "<t>.<raw request body>" cun tes secret sco clav. Per verifitgar:

  1. Prenda ils bytes dal corp raw exactamain sco retschavids (avant mintga parsing JSON).
  2. Calculescha HMAC-SHA256 da t + "." + body cun tes secret, sco hex minuscul.
  3. Cumpareglia el cun v1 en temp constant.
  4. Refusa l'event sch'il t è dapli che 5 minutas davent da tes ura (protecziun cunter repetiziuns).

In receptader cumplet en Node.js (Express) e 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);
});

Tips

  • Respunda svelt e metta en la fila tes agen processament.
  • Il secret appartegna a la clav API che ha inizià l'execuziun. Clavs en differents servetschs han secrets differents.
