Erstellung eines Workflows in n8n über Webhook

Fortgeschritten

Dies ist ein Engineering-Bereich Automatisierungsworkflow mit 11 Nodes. Hauptsächlich werden If, Set, Code, Webhook, HttpRequest und andere Nodes verwendet. Dynamische Arbeitsabläufe programmatisch durch Webhook und n8n API erstellen

Voraussetzungen
  • HTTP Webhook-Endpunkt (wird von n8n automatisch generiert)
  • Möglicherweise sind Ziel-API-Anmeldedaten erforderlich
