# Relay Route

`POST /api/integrations/relay/route`

Record a thread→owner route created by a relay (local) mention.

When a mention runs on the desktop, cloud never sees the project, so the
desktop reports the thread mapping here; without it, later replies in the
thread have no route and cloud would drop them. First writer wins.

The caller may only record routes for a workspace it has a live Slack
install in. The route is keyed on Slack coordinates alone, so without this
check any authenticated API key could squat or mis-route another tenant's
threads.
