# n8n-Integration
|
||||
|
||||
## Empfohlene Node-Reihenfolge
|
||||
|
||||
```text
|
||||
Schedule Trigger
|
||||
-> PostgreSQL: aktive Kunden laden
|
||||
-> Loop Over Items
|
||||
-> PostgreSQL: Monatsmetriken und Verlauf laden
|
||||
-> Code: Monatsdaten vorbereiten
|
||||
-> Code: Claude Request bauen
|
||||
-> HTTP Request: Anthropic Messages API
|
||||
-> Code: Claude JSON extrahieren
|
||||
-> Code: Render Payload bauen
|
||||
-> HTTP Request: Report Renderer /render
|
||||
-> Speicher / E-Mail / Kundenportal
|
||||
-> PostgreSQL: Reportlauf protokollieren
|
||||
```
|
||||
|
||||
## Anthropic HTTP Request
|
||||
|
||||
- Methode: `POST`
|
||||
- URL: `https://api.anthropic.com/v1/messages`
|
||||
- Header:
|
||||
- `x-api-key`: aus Credential oder Secret
|
||||
- `anthropic-version`: `2023-06-01`
|
||||
- `content-type`: `application/json`
|
||||
- Body: `={{ $json.claudeRequest }}`
|
||||
- Response: JSON
|
||||
|
||||
## Renderer HTTP Request
|
||||
|
||||
- Methode: `POST`
|
||||
- URL im gleichen Docker-Netz: `http://report-renderer:8080/render`
|
||||
- Body Content Type: JSON
|
||||
- Body: gesamtes aktuelles Item
|
||||
- Response Format: File
|
||||
- Binary Property: `data`
|
||||
|
||||
Danach kann `data` als E-Mail-Anhang, S3-Upload oder Datei verwendet werden.
|
||||
|
||||
## Datenschutz und Fehlerbehandlung
|
||||
|
||||
- Jeden Kunden im Loop als separates Item verarbeiten.
|
||||
- Kunden-ID und Berichtsmonat vor jedem Node erhalten.
|
||||
- Bei Claude- oder Renderfehlern keinen leeren Report versenden.
|
||||
- Reportlauf erst nach erfolgreicher Ablage als `completed` markieren.
|
||||
- Eindeutigen DB-Schluessel auf Kunde, Jahr und Monat setzen.
