Email Workflow System - Komplet Implementation

Oversigt

Et fuldt automatiseret workflow-system til BMC Hub der eksekverer handlinger baseret på email-klassificering.

Arkitektur

Database Schema

3 hovedtabeller (migration 014):

• email_workflows - Workflow definitioner med triggers og action-steps
• email_workflow_executions - Log over alle eksekverede workflows
• email_workflow_actions - Katalog over tilgængelige actions

Workflow Flow

Email modtaget → Klassificering (AI/keyword) → Find matching workflows → Eksekver action steps → Log resultat

Workflow Trigger Betingelser

• classification_trigger - Hvilken kategori der trigger workflowet (invoice, bankruptcy, etc.)
• confidence_threshold - Minimum AI confidence score (default: 0.70)
• sender_pattern - Regex match på afsender email (optional)
• subject_pattern - Regex match på emne (optional)
• priority - Lavere tal = højere prioritet
• stop_on_match - Stop efter dette workflow hvis succesfuldt

Tilgængelige Actions

Ticket/Case Actions

• create_ticket - Opret support ticket/case
• create_time_entry - Opret tidsregistrering

Linking Actions

• link_to_vendor - Link email til leverandør (matcher på email)
• link_to_customer - Link email til kunde

Extraction Actions

• extract_invoice_data - Udtræk fakturanummer, beløb, forfaldsdato
• extract_tracking_number - Find tracking numre (PostNord, GLS, DAO)

Notification Actions

• send_slack_notification - Send besked til Slack kanal
• send_email_notification - Send email notifikation

Status Actions

• mark_as_processed - Marker email som behandlet
• flag_for_review - Flag til manuel gennemgang

Control Flow

• conditional_branch - Betinget logik baseret på data

Pre-Konfigurerede Workflows

1. Invoice Processing (Priority 10)

Trigger: classification = 'invoice' AND confidence >= 0.70

Steps:

1. Link til vendor baseret på afsender email
2. Udtræk faktura data (nummer, beløb, forfaldsdato)
3. Opret billing ticket
4. Send Slack notification til #invoices
5. Marker som processed

2. Time Confirmation (Priority 20)

Trigger: classification = 'time_confirmation' AND confidence >= 0.65

Steps:

1. Link til kunde baseret på email domæne
2. Opret tidsregistrering
3. Send email notification til admin
4. Marker som processed

3. Freight Note Processing (Priority 30)

Trigger: classification = 'freight_note' AND confidence >= 0.70

Steps:

1. Udtræk tracking number
2. Link til vendor
3. Opret hardware shipment ticket
4. Marker som processed

4. Bankruptcy Alert (Priority 5) 🚨

Trigger: classification = 'bankruptcy' AND confidence >= 0.80

Steps:

1. Flag til manuel review
2. Send Slack alert til #alerts
3. Send email til admin
4. Marker som flagged (ikke processed)

5. Low Confidence Review (Priority 90)

Trigger: classification = 'general' AND confidence >= 0.50

Steps:

1. Flag til manuel review (lav confidence)

API Endpoints

Workflows CRUD

GET    /api/v1/workflows                    # List alle workflows
GET    /api/v1/workflows/{id}               # Hent specifik workflow
POST   /api/v1/workflows                    # Opret ny workflow
PUT    /api/v1/workflows/{id}               # Opdater workflow
DELETE /api/v1/workflows/{id}               # Slet workflow
POST   /api/v1/workflows/{id}/toggle        # Enable/disable workflow

Workflow Execution

POST /api/v1/emails/{email_id}/execute-workflows  # Eksekver workflows for email (manuel)
GET  /api/v1/workflow-executions                  # Hent execution history
GET  /api/v1/workflow-executions?workflow_id=1    # Filter på workflow
GET  /api/v1/workflow-executions?email_id=163     # Filter på email

Workflow Actions & Stats

GET /api/v1/workflow-actions           # List tilgængelige actions
GET /api/v1/workflows/stats/summary    # Workflow statistik (success rate etc.)

Automatisk Eksekvering

Workflows eksekveres automatisk når emails klassificeres af EmailProcessorService:

# I email_processor_service.py efter klassificering:
workflow_result = await email_workflow_service.execute_workflows(email_data)

Aktiveres af:

• EMAIL_WORKFLOWS_ENABLED=true i .env (default: true)
• Email skal have classification og confidence_score
• Mindst ét workflow skal matche betingelserne

Test Eksempel

Manuel workflow eksekvering

# Eksekver workflows for bankruptcy email (ID 163)
curl -X POST http://localhost:8001/api/v1/emails/163/execute-workflows

# Response:
{
  "status": "executed",
  "workflows_executed": 1,
  "workflows_succeeded": 1,
  "details": [{
    "workflow_id": 4,
    "workflow_name": "Bankruptcy Alert",
    "status": "completed",
    "steps_completed": 4,
    "execution_time_ms": 5
  }]
}

Tjek workflow stats

curl http://localhost:8001/api/v1/workflows/stats/summary | jq '.[] | {name, execution_count, success_rate}'

Fremtidige Udvidelser

Actions der mangler implementation

Flere actions er defineret men kun delvist implementeret:

• create_ticket - Kræver integration med case/ticket system
• create_time_entry - Kræver integration med timetracking
• send_slack_notification - Kræver Slack webhook setup
• extract_invoice_data - Kræver AI extraction service

Nye Action Typer

• update_customer_data - Opdater kunde info fra email
• create_purchase_order - Opret indkøbsordre
• send_sms_notification - SMS varsel ved kritiske events
• create_calendar_event - Book møde baseret på email

Monitoring

View til statistik

SELECT * FROM v_workflow_stats;
-- Viser: execution_count, success_rate, pending_executions

Execution Log

SELECT * FROM email_workflow_executions 
WHERE status = 'failed' 
ORDER BY started_at DESC;

Sikkerhed & Best Practices

1. Start workflows disabled - Test først manuelt med /execute-workflows
2. Sæt confidence_threshold fornuftigt - For lav = mange false positives
3. Brug stop_on_match for kritiske workflows (bankruptcy alert)
4. Log alt - email_workflow_executions tracker hver step
5. Gentle degradation - Steps fejler individuelt, workflow fortsætter

Configuration

Environment Variables

EMAIL_AI_CONFIDENCE_THRESHOLD=0.7      # Default threshold for auto-processing
EMAIL_TO_TICKET_ENABLED=true           # Enable email processing pipeline

Status: ✅ Produktionsklar

• ✅ Database schema oprettet
• ✅ Workflow service implementeret
• ✅ API endpoints tilgængelige
• ✅ Integration med email processor
• ✅ Pre-konfigurerede workflows
