✈️ Berechnung des CO2-Fußabdrucks von Geschäftsreisen mit CarbonInterface API und GPT-4o
Dies ist ein Other, AI, IT Ops-Bereich Automatisierungsworkflow mit 12 Nodes. Hauptsächlich werden SplitOut, HttpRequest, GmailTrigger, GoogleSheets, SplitInBatches und andere Nodes verwendet, kombiniert mit KI-Technologie für intelligente Automatisierung. ✈️ Berechnung von CO2-Emissionen für Geschäftsreisen über Carbon Interface API und GPT-4o
- •Möglicherweise sind Ziel-API-Anmeldedaten erforderlich
- •Google-Konto + Gmail API-Anmeldedaten
- •Google Sheets API-Anmeldedaten
- •OpenAI API Key
