Add or Replace Staff Note

Sets a staff member’s note for a date. Shared rules: see Writing Data.

• There is one note per staff member per date.
• No note on that date: a note is created (201, action: created).
• A note already exists: its text is replaced (200, action: updated). If several exist, the newest is replaced. Images and the original creator and created_on are kept.
• CRM and business-contact notes are never touched.
• The staff member gets an app notification (“Admin has added a new note.” or “Admin has updated a note.”).
• Editing notes any other way, and deleting notes, is not available. Use List Staff Notes to read notes back.

Custom role needs: staff_details:edit.
