​

Enter your Endpoint URL — the web address on your external system that will receive the data. Your integration partner should be able to provide this.
​
​NOTE - You can use Svix Play, linked below the Endpoint URL box, to test your endpoint with sample data before connecting a live system. This is the recommended first step when setting up a new endpoint.

Optionally, add a Description to identify what this endpoint is used for
​

Select the events you want this endpoint to receive (see Event Catalog below), or leave unfiltered to receive all events

Clicking the Menu on the top right of the endpoint configuration provides you with additional options for message management, along with the ability to disable or delete the endpoint:

​

NOTE — While the Webhooks application is set up once, you can configure multiple endpoints to meet your requirements. All of your configured endpoints will be listed on the Endpoints tab. Click on an endpoint to view its activity.

​

Once configured and transactions are flowing, the message attempts will be listed at the bottom of the Endpoints tab. The list can be filtered, and clicking through on a message will display the message content:

The Event Catalog tab lists every event type that Line-Up can send. You can browse it from the Webhooks area or access it directly when configuring an endpoint.
​

Events are grouped by category. You can subscribe an endpoint to individual events or to an entire category. Additional event types will be added as the platform develops.

​

Each event in the list can be expanded to show the technical details of that event:

The Logs tab provides a record of every webhook delivery attempt, including the payload sent when you click through on the message. You can filter the list for specific events and time periods you're interested in:

The Activity tab gives a high-level view of webhook throughput across your account, including delivery success rates over time. This is useful for monitoring the overall health of your webhook configuration at a glance.

Check the message attempts list on the endpoint configuration for failed messages. Common causes include:

Confirm that your endpoint is subscribed to the relevant event types. If you have filtered by event, check the Event Catalog to ensure you have the correct selection.
