# `key_cannot`

**HTTP 403** · This key cannot do that.

## Why it happens

Each key type has fixed permissions: `delivery` reads published content, `preview` reads drafts, `management` can also write.

An agent can also do only what the person who connected it can: their role, and, if an owner limited them, only [some content types or entries](../guides/team.md#limit-what-someone-can-edit). Then the message says what's allowed, like `You can only change entries of Event (event).`

## How to fix it

To write you need a `management` key. To read drafts, a `preview` key. See the key types in the API docs. If the message says what you *can* change, work inside that, or ask an owner or admin to widen the person's access in Team.

## Example

```json
{
  "error": {
    "code": "key_cannot",
    "message": "This key cannot do that.",
    "fix": "To write you need a management key. To read drafts, a preview key. See the key types in the API docs.",
    "doc_url": "https://pluma.so/docs/errors/key_cannot"
  }
}
