# Delete a lesson

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

Operation ID: `lessons.delete` · API v3

Moves the lesson to the trash. Trashed lessons can be restored by setting `deleted` to `false` with the update operation.

A lesson that is the source of connected lessons cannot be deleted and returns `state_conflict`; disconnect those lessons first. Replicated lessons are read-only and cannot be deleted; such requests return `replica_readonly`.

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

Required permissions: `lessons.delete`.

|---|---|---|---|---|

| `lesson_id` | path | string | yes |  |
