express-webhook

Express Webhook Receiver

This example receives APIDot task callbacks at POST /api/apidot/webhook.

Run

cd webhooks/express-webhook
npm install
npm start

For local webhook testing, set APIDOT_ALLOW_UNLISTED_TASK_IDS=true or set APIDOT_KNOWN_TASK_IDS to the task ids you submitted. In production, replace the in-memory Set with your own database lookup and keep APIDOT_ALLOW_UNLISTED_TASK_IDS unset.

Expose the local server with a secure tunnel during development, then pass that public URL as callback_url in submit requests.

{
  "callback_url": "https://example.com/api/apidot/webhook"
}

Production notes

• Store task updates in a database instead of an in-memory Set.
• Only process callback task_id values that your system submitted and recorded.
• Keep the response path short: persist or enqueue the callback, return 2xx quickly, and reconcile with GET /api/generate/status/{task_id} using a timeout before irreversible business actions.
• Make the handler idempotent. In production, use task_id plus a status version, update time, or business unique key; do not rely only on an in-memory Map.
• Keep API keys and production callback URLs out of public repositories.
• Return a 2xx response only after your application has accepted the callback.
