Translate all or specific areas of the HTML document that makes up a website into another language.

Note

Please note the following before use:

Text with images cannot be translated.
Some styles applied to text may not match or may be omitted.
Some links or actions applied to the text may not work or may be omitted.
HTML parameter size limit exists: 200,000 bytes including all characters including UTF-8-based tags, spaces, etc.
Larger HTML parameter sizes result in slower responses, so we recommend requesting element in the translation area.
- See Website Translation examples
Recommended maximum characters per call: 60,000 characters
Recommended maximum characters per minute: 3,600,000 characters
Billing: All characters counted, including tags and spaces.

Request body

You can include the following data in the body of your request:

Field	Type	Required	Description
`source`	String	Required	Language code of the source text (source) `auto` (automatic language detection) \| `ko` (Korean) \| `en` (English) \| `ja` (Japanese)\| `zh-CN` (Chinese (Simplified)) For information about language pairs for which translation is supported, see Languages supported for translation
`target`	String	Required	Language code of the target text `ko` (Korean) \| `en` (English) \| `ja` (Japanese)\| `zh-CN` (Chinese (Simplified)) For information about language pairs for which translation is supported, see Languages supported for translation
`html`	String	Required	Element of the entire HTML document or specific areas to translate Up to 200,000 bytes can be entered (including UTF-8-based tags and spaces)

Note

Even without specifying the source language (specified to auto), it automatically detects the language and provides a translation result. In this case, additional fees do not incur for detecting languages but only for the number of characters requested for translation.
