Session Notes API

Available in arize-phoenix 14.16.0+ Phoenix now supports creating session notes through POST /v1/session_notes, giving session-level review workflows the same note-specific REST pattern used by traces and spans. To keep note behavior consistent across APIs, the reserved annotation name note is no longer accepted on the generic session annotation endpoint. Use the dedicated note endpoint instead:
  • POST /v1/session_notes for session notes
  • POST /v1/session_annotations for regular session annotations
