# Get related lessons

> Returns other resources (campaigns, triggers, etc.) that reference this lesson.

Get resources (campaigns, triggers) referencing this lesson

**A missing record does not return 404.** This handler reports the failure without a status code, and the error envelope defaults to HTTP `200` — you get `200` with `status: "failed"`. Branch on `status`, not on the HTTP code.

      description: >-
        Team scope for the request, as one or more team ObjectIds. The brackets
        are required: PHP keeps only the last value for a repeated plain key, so
        `teams=A&teams=B` silently resolves to B alone. On requests with a JSON
        body you may send `teams` (no brackets) in the body instead.


        **Values that are not valid ObjectIds are silently ignored** — a
        mistyped team ID behaves as if no team was sent. See the [teams section
        of the API conventions guide](/guides/api-conventions#team-scoping).
