📄 Description

Description

Add a worked example to the LangSmith Engine webhooks reference page showing how to forward webhook events to a Slack channel. The example uses a small FastAPI receiver that verifies the shared secret, transforms the event envelope into Slack's incoming-webhook schema, and posts the message — since the Engine event JSON doesn't match Slack's expected payload shape.

Release Note

Docs: added a Slack channel forwarding example to the LangSmith Engine webhooks reference.

Test Plan

  • Render the page locally with make dev and confirm the new Post events to a Slack channel section, <Steps>, and code block display correctly.

Opened collaboratively by Mason Daugherty and open-swe.
