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. > A Note is a freeform text activity on a Lead ## API Docs - Notes [List or filter all Note activities](https://developer.close.com/api/resources/activities/notes/list.md) - Notes [Create a Note activity](https://developer.close.com/api/resources/activities/notes/create.md) - Notes [Get a single Note activity](https://developer.close.com/api/resources/activities/notes/get.md) - Notes [Update a Note activity](https://developer.close.com/api/resources/activities/notes/update.md) - Notes [Delete a Note activity](https://developer.close.com/api/resources/activities/notes/delete.md) ## OpenAPI Specification The raw OpenAPI 3.1 specification for this API is available at: - [OpenAPI JSON](https://developer.close.com/api/resources/activities/notes/openapi.json) - [OpenAPI YAML](https://developer.close.com/api/resources/activities/notes/openapi.yaml)
