# Remove an attachment

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

Operation ID: `lessons.attachments.delete` · API v3

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. Replicated lessons are read-only, and requests to change them return `replica_readonly`.

Required permissions: `lessons.update`.

|---|---|---|---|---|
| `product_id` | path | string | yes |  |
