Notes

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. 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 <br /> tags.
