# Knowledge API
### 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:
```javascript
Authorization: Bearer {API_KEY}
```
This API is based on an existing knowledge and creates a new document through text based on this knowledge.
### Params
Knowledge ID
### Request Body
Document name
Document content
Index mode
- high_quality

- rules
(object) Custom rules (in automatic mode, this field is empty)
- pre_processing_rules

- id
(string) Unique identifier for the preprocessing rule
- enumerate
- remove_extra_spaces
