This documents the webhook payload that Host Tools will POST to your configured webhook URL when a listing is added, changed or deleted.

Note: This is not an API endpoint you call.
This documents the requests that Host Tools sends TO your webhook URL.

When triggered:

• listing.created: a listing is added (imported or created)
• listing.changed: a field returned by /api/getListing changes (for example the name, description, photos, prices or settings). Several edits within 30 seconds are sent as one webhook with the latest data.
• listing.deleted: a listing is deleted

A listing joining or leaving a listing group is sent as listingGroup.changed, not listing.changed.

Handling the webhook:

1. Your endpoint should respond with HTTP 200 status
2. Process the data asynchronously if needed
3. Respond within 30 seconds
