# Replace lesson content

`PUT https://api.cademi.com.br/api/v3/products/{product_id}/lessons/{lesson_id}/content`

Operation ID: `lessons.content.update` · API v3

Replaces the lesson body and, when `video` is included, the lesson video. The `inherited` field returned by the retrieve operation is accepted and ignored, so retrieved content can be sent back as is.

`raw` blocks are not accepted, embed blocks must use a recognized provider, and quiz lessons do not accept a video. The request body must not exceed 1 MiB.

The content of a connected lesson belongs to its source lesson and cannot be changed; such requests fail with `state_conflict`. Replicated lessons are read-only, and requests to change them return `replica_readonly`.

Send the lesson's current `ETag` in the `If-Match` header to avoid overwriting a newer version.

Required permissions: `lessons.update`.
