# Knowledge API

<div>
  ### Authentication

  Service API of Dify authenticates using an `API-Key`.

  It is suggested that developers store the `API-Key` in the backend instead of sharing or storing it in the client side to avoid the leakage of the `API-Key`, which may lead to property loss.

  All API requests should include your `API-Key` in the **`Authorization`** HTTP Header, as shown below:

  <CodeGroup title="Code">
    ```javascript
      Authorization: Bearer {API_KEY}

    ```
  </CodeGroup>
</div>

  url='/datasets/{dataset_id}/document/create-by-text'
  method='POST'
  title='Create a Document from Text'
  name='#create-by-text'
/>
<Row>
  <Col>
    This API is based on an existing knowledge and creates a new document through text based on this knowledge.
