# Link

> Link element detail data structure.

When [`Element`](/en/api-reference/supernote-plugin/types/trail) has `type === 600`, `element.link` provides link details.

<Note>
  `Link.linkType` indicates the link type read from the file. Supported `linkType` ranges may differ across write APIs; for example, parameter validation in `insertTextLink` and `modifyLassoLink` currently only allows `0..4`.
