Creating a Webhook

1

Open Webhook Settings

In the Sessionboard admin dashboard, navigate to Settings > Integrations > Webhooks.Webhook settings panel
2

Add an Endpoint

Click Add Endpoint and enter the URL where you want to receive webhook deliveries. This must be a publicly accessible HTTPS endpoint. Select which events you want to subscribe to for this endpoint.Adding a webhook endpoint
3

Save and Activate

Save the webhook configuration. Sessionboard will begin sending events to your endpoint immediately. You can also add custom headers for additional security (e.g., passing a token that your server validates to ensure the request is from Sessionboard).

​
Testing Webhooks

Use the Testing tab on any endpoint to send a sample payload without triggering a real action. You can also use Svix Play to capture and inspect deliveries in a temporary sandbox. Testing a webhook endpoint

​
Monitoring

Sessionboard provides delivery logs for each webhook endpoint in the admin dashboard. You can view recent deliveries, inspect payloads, and check response status codes. Failed deliveries are retried automatically with exponential backoff. Webhook delivery logs
