# Get Knowledge Base Article Content API

Retrieve the content of a Knowledge Base article in a specific language. Content can be returned as either Markdown or HTML.

## Endpoint

```
GET /v1/knowledgebase/articles/{correlationId}/content/{lang}
```

## Path Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `correlationId` | string | Yes | The article identifier. This can be your own correlation ID from import, or the internal Product Fruits article ID prefixed with<br>`pf_`<br>. |
| `lang` | string | Yes | The language code for the article content, for example<br>`en`<br>. |

## Query Parameters

| Parameter | Type | Required | Default | Description |
| --- | --- | --- | --- | --- |
| `format` | string | No | `markdown` | Determines the response content format. Supported values are<br>`markdown`<br>and<br>`html`<br>. |

## Format Behavior

Knowledge Base articles are originally imported into Product Fruits as Markdown.

However, after a user edits and saves an article in the Product Fruits editor, HTML becomes the canonical source of the article content. This can affect how Markdown responses are generated.

### `format=html`

Returns the current canonical HTML content. Use this format when you need the most accurate representation of the article as it currently exists in Product Fruits.

### `format=markdown`

Returns Markdown content.

Behavior depends on whether the article has been edited after import:

-   If the article has not been edited since import, the original Markdown is returned unchanged.
-   If the article has been edited, the current HTML content is converted back to Markdown.

Because some HTML elements do not have a direct Markdown equivalent, converted Markdown responses may include a `conversionResults` array. This array describes any elements that were dropped, simplified, or changed during conversion.

Examples of possible conversion limitations include:

-   iframe embeds
-   video embeds
-   custom HTML blocks
-   table styling
-   code-block language hints

`conversionResults` is empty when:

-   `format=html` is used, or
-   the original Markdown is returned unchanged.

GET /v1/knowledgebase/articles/rich-md-fixture/content/en?format=markdown

## Conversion Result Object

When Markdown is requested for an article that has been edited in the Product Fruits editor, the API may convert the current HTML back to Markdown. Any lossy or simplified conversions are listed in `conversionResults`.

| Field | Type | Description |
| --- | --- | --- |
| `type` | string | Type of conversion result, for example<br>`dropped`<br>or<br>`simplified`<br>. |
| `element` | string | HTML element affected by the conversion. |
| `count` | number | Number of affected elements. |
| `message` | string | Human-readable explanation of the conversion result. |

## Error Responses

| Status Code | Description |
| --- | --- |
| `400` | Missing<br>`correlationId`<br>or<br>`lang`<br>. |
| `401` | Missing or invalid authentication token. |
| `404` | Article not found, or content for the requested language does not exist. |

## Notes

For the most accurate content representation, use `format=html`.

Use `format=markdown` when you need Markdown output, but check `conversionResults` to detect whether any HTML elements were lost or simplified during conversion.
