Notes and activities
Create a note
Adds a note to one of the calling user’s contacts. contact_id, title, and body are required. Attach files by URL with attachments_attributes or assets_attributes; files are added to the company’s asset library. Returns 201 with the note, or 206 with the note when some files could not be attached (listed in meta.attachment_errors) or the contact has no company (meta.assets_skipped). Returns 404 when the contact does not belong to the calling user and 422 on validation errors. Requires a rep token or an admin-tier token tied to a user; admin users need the members manage permission (or customers update).
