Has anyone of you experience with the open source workflow tool n8n? And was also able to fetch incidents via the Director API and has built a n8n workflow which is also considering some error handling (token refresh, HTTP errors during polling etc.)?

 

I have built a PoC workflow which seem to work to fetch incidents, but it is in a very early stage. Maybe we (the community) can try to build a nice workflow which can be used by everyone here?

The workflow looks like this:

n8n Director IP Incident Fetch Workflow

You have to replace “<LP-API-URL>”, "<YOUR SECRET>" and "<YOUR TOKEN>" befor importing it to n8n:
