Webhooks

Learn about using webhooks to receive notifications of events.

Configuring Webhooks

You can configure endpoints in each workspace for an app to receive webhook event notifications for resources, such as devices and connected accounts.

To configure webhook endpoints:

1. In the left navigation pane of the Seam Console, click Webhooks.

2. Click + Add Webhook.

3. In the Create Webhook dialog, type your webhook URL and select the event types for which you want to receive events.

4. Click Create.

5. Copy your webhook secret and store it somewhere secure. You use this webhook secret to validate the payloads that you receive on your webhook.

You can add webhooks through the Seam Console or programmatically. Let's start by looking at how to add and test a webhook using the Seam Console.

Click + Add Webhook to create a webhook for your device events.

You can specify any public URL endpoint to receive webhook events by pasting the URL into the Create Webhook dialog.

You can specify any internet-accessible URL as your webhook URL.

Webhook endpoints can receive many different types of events, such as device.connected or device.low_battery. It's a good idea when getting started with webhooks to review the list of webhook event types and test your endpoint using the Svix sandbox environment.

The Svix sandbox environment enables you to test sending requests to an endpoint.

You can view all the event types and the included fields in the Event Catalog tab.

Go to the "Event Catalog" tab to view all available events.

We use webhooks from Svix. For more information about consuming events, such as testing or verifying webhooks, see the Svix docs.

Retry Schedule for Webhooks

Seam delivers each webhook event based on a retry schedule with exponential backoff. Each message is attempted based on the following schedule, where each period is started following the failure of the preceding attempt:

• Immediately

• 5 seconds

• 5 minutes

• 30 minutes

• 2 hours

• 5 hours

• 10 hours

• 10 hours (in addition to the previous)

For example, an attempt that fails three times before eventually succeeding will be delivered roughly 35 minutes and 5 seconds following the first attempt.

If you remove or disable a webhook, delivery attempts to the endpoint are disabled as well.
