# Update a Note activity

`PUT /activity/note/{id}/`

**`note_html` and `note`**: setting one overwrites the other. If both are provided, `note_html` takes precedence. `note_html` supports rich-text HTML; `note` is plaintext only.

A note can be pinned or unpinned by setting `pinned` to `true` or `false`.
