Hey,
I’m familiar with all kinds of ETL processes and automation tools, but n8n is new to me. So I hope the expertise of all of you can help me achieve my goal:
I want to create appointments in my Google Calendar but the feed with appointments to make always contains everything.
So I get a list of appointments I want to create from an HTTP node, but I need to exlude appointments that are already there.
So far I’m able to retrieve the requested appointments from an API, and in the same workflow (but a parallel path) I’m able to retrieve the already existing appointments from my Google Calendar.
Both paths meet eachother again in an merge node.
But now I need to exclude the existing appointments from the incoming feed.
I’ve tried several ways already, but basically what I’m missing is an option in the filter node that checks a property of an item against an array.
