--- title: Notes subtitle: A Note is a freeform text activity on a Lead --- A Note is a freeform text activity on a Lead. **About `note_html` and `note` parameters:** Notes can be created/updated using either parameter, but **setting one will overwrite the other**. If both are in the same request, `note_html` takes precedence. - `note_html` is the preferred input. It supports rich-text content through a [subset of HTML](/api/overview/rich-text). Setting it will populate `note` with a plaintext representation, without guarantees about preserving formatting. - `note` is for plaintext only. Setting it will populate `note_html` by escaping HTML code and replacing newlines with `
` tags.
