This guide provides information on using Hookdeck Event Gateway to publish events to Outpost.

Setup the Outpost API as a Destination

To publish to Outpost via the Event Gateway, you can set your HTTP destination to point to the Outpost Publish API endpoint (https://api.outpost.hookdeck.com/2025-07-01/publish).

Enable Bearer Authentication with your Outpost API key.

Payload shape & transformation

The payload shape must match the expected shape of the Publish API endpoint.

You can use a transformation to modify the payload shape before it is published to Outpost.
