Webhooks into your pipeline

Drop finished takes straight into your project folder, Slack or n8n.

Create the take with a webhook

const TAKES = "https://edengen.ai/v1";
const H = { Authorization: `Bearer ${process.env.TAKES_API_KEY}`, "Content-Type": "application/json" };

const res = await fetch(`${TAKES}/takes`, {
  method: "POST",
  headers: { ...H, Prefer: "wait=60" },
  body: JSON.stringify({
    model: "kling-3",
    prompt: "A small white creature looks up at the lightning and blinks, no music",
    resolution: "720p",
    duration: 5,
    webhook_url: "https://your.app/hooks/takes",
  }),
});
const take = await res.json();
console.log(take.status, take.cost_usd, take.output?.url);

Receive and verify

server.js

import express from "express";
import { verify } from "./verify.js";            // from the Webhooks page

const app = express();
app.post("/hooks/takes", express.raw({ type: "application/json" }), async (req, res) => {
  if (!verify(req.body.toString(), req.get("X-Takes-Signature"), process.env.TAKES_WEBHOOK_SECRET)) return res.sendStatus(401);
  const { event, take } = JSON.parse(req.body);
  res.sendStatus(200);                              // answer fast, work after
  if (event === "take.completed") await saveToDrive(take.output.url, take.output.filename);
  else await notify(`Take ${take.id} failed and was refunded: ${take.error}`);
});
app.listen(3000);

n8n or Make
Use a Webhook trigger node as the webhook_url, then an HTTP node to fetch take.output.url with your key. Verify the signature in a Code node with the same function.
