# Get a lesson

> Returns a single lesson by ID.

Get a single lesson

**Permission:** Requires `lessons` **or** `campaigns`. Passing `count=true` bypasses the check. Denials read `Manage Lessons or Campaigns`.

**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).
