Remove an attachment
/products/{product_id}/lessons/{lesson_id}/attachments/{file_id}Removes the attachment from the lesson body. The underlying file is not deleted.
Attachments without a file_id cannot be removed with this operation; remove them by replacing the lesson content instead.
Send the lesson's current ETag in the If-Match header to avoid overwriting a newer version. Replicated lessons are read-only, and requests to change them return replica_readonly.
Autonomous mode: the API credential secret, sent as a bearer token. Credential secrets are identified by a fixed prefix.

Path Parameters
Public ID of the product, prefixed with prd_.
Public ID of the lesson, prefixed with les_.
Public ID of the file, prefixed with file_.
Header Parameters
Client-generated key that makes the request safe to retry. Must be 1 to 128 characters from [A-Za-z0-9._:-]. Optional on this operation; when sent, a malformed key returns idempotency_key_invalid, and repeating the request with the same key and the same body returns the stored result with Idempotent-Replayed: true.
Expected revision of the resource, in the same format as the ETag header (W/"<type>:<id>:<revision>"). If the resource has changed since that revision, the request fails with 412 and the revision_mismatch error code. * matches the current revision. Any other value fails with 400 and the if_match_invalid error code. When omitted, the update is applied to the current revision.
Optional client-generated identifier of the request, up to 64 characters from [A-Za-z0-9._-]. Echoed back in the response and recorded in the request log; it never replaces the server-generated X-Request-Id.

curl -X DELETE "https://example.com/products/string/lessons/string/attachments/string"Add or update an attachment PUT
Attaches a file to the lesson body, or updates the title and kind of an existing attachment for the same file. The operation is idempotent per file ID: it returns `201` when the attachment is added and `200` when an existing attachment is updated. Send the lesson's current `ETag` in the `If-Match` header to avoid overwriting a newer version. Replicated lessons are read-only, and requests to change them return `replica_readonly`.
Retrieve a lesson connection GET
Returns whether the lesson is connected to a source lesson and, if so, identifies the source lesson, its product, and its module. Lessons without a connection return `connected` set to `false`.
