  • Inbound Webhook Code-Beispiele

Sie können SIGNL4-Alarme per Inbound-Webhook auslösen. Dies ist ein einfacher und zuverlässiger Weg zur Integration mit Ihren Backend-Systemen. Zu diesem Zweck haben wir einige Code-Beispiele aufgelistet, wie Sie Webhook-Anfragen an SIGNL4 senden können. Sie müssen hier entsprechend durch Ihr SIGNL4-Teamgeheimnis ersetzen und können je nach Bedarf zusätzliche Parameter zu den Alarm-Daten hinzufügen.
Informationen zum Setup der Webhooks findest du in unserer  Getting-Started-Dokumentation.
