Send HTTP POST notifications to external services whenever specific events occur in your organization.
Creating an Outgoing Webhook

/admin/webhooks) and select the Outgoing tab
- Click Add Webhook

Webhook Payload
Each delivery includes a JSON body with the event type, timestamp, and relevant resource data. Headers include a signature for verification (see Security below).
Delivery Stats and Retries
The webhooks table shows delivery statistics for each endpoint:
- Success rate — Percentage of successful deliveries (2xx responses)
- Last delivery — Timestamp and status of the most recent attempt
- Total deliveries — Count of all delivery attempts
Failed deliveries are retried automatically with exponential backoff (up to 3 retries over 1 hour).
Incoming Webhooks
Receive data from external services by generating unique webhook URLs.
Creating an Incoming Webhook
- Select the Incoming tab
- Click Add Webhook
- Name the webhook and configure the action (e.g., create a project, add a note)
- Copy the generated URL and configure it in your external service
Each incoming webhook gets a unique URL in the format:
https://app.thig.ai/api/webhooks/incoming/{webhook-id}
Webhook Security
All outgoing webhook deliveries are signed with HMAC-SHA256 for verification.
Verifying Signatures
Each delivery includes these headers:
| Header | Description |
|---|
webhook-id | Unique identifier for the delivery |
webhook-signature | HMAC-SHA256 signature of the payload |
webhook-timestamp | Unix timestamp of the delivery |
Always verify webhook signatures before processing payloads. Ignoring verification exposes your endpoint to spoofed requests.
Best Practices
- Handle retries idempotently — Use the
webhook-id header to deduplicate deliveries. The same event may be delivered more than once.
- Respond quickly — Return a 2xx status within 10 seconds. Do heavy processing asynchronously after acknowledging receipt.
- Monitor failures — Check the delivery stats regularly. Webhooks with repeated failures are automatically disabled after consecutive failures.
- Use HTTPS — Only HTTPS endpoints are accepted for outgoing webhooks.
Test your webhook endpoint with the Send Test button before subscribing to real events. It sends a sample payload so you can verify your integration works.
Webhooks are available to Admin and Owner roles. Members and Viewers cannot configure webhooks.
