# Rich text notes on Opportunities

[Opportunities](https://developer.close.com/api/resources/opportunities/list) now support a `note_html` field for
rich text notes, alongside the existing plaintext `note` field.

When you [create](https://developer.close.com/api/resources/opportunities/create) or
update an opportunity:

- Providing `note_html` makes it the source of truth. The plaintext `note` is
  automatically derived from it, overriding any `note` sent in the same request.
- On update, sending `note_html: null` clears both `note_html` and `note`.
- When you send only `note` and the opportunity already has a `note_html`, the
  rich text version is re-derived from the new `note`.

The `note_html` field is always included in opportunity responses (it may be
`null`), but is excluded from CSV and JSON exports.
