# Process Session Messages

`POST /v1/messages/sessions/{session_id}/process`

Process all stored messages in a session that were previously stored with process_messages=false.
    
    **Authentication Required**: Bearer token, API key, or session token
    
    This endpoint allows you to retroactively process messages that were initially stored 
    without processing. Useful for:
    - Processing messages after deciding you want them as memories
    - Batch processing large conversation sessions
    - Re-processing sessions with updated AI models
    
    **Processing Behavior**:
    - Only processes messages with status 'stored_only' or 'pending'
    - Uses the same smart batch analysis (every 15 messages)
    - Respects existing memory creation pipeline
