Describe the problem/error/question

Hi,

I am a new user and have self hosted n8n on Railway.app platform.

This is my first query.

I am building a workflow in which I want to fetch data from an API which is returned in JSON format and then save this data to a database.

I am trying to check in Supabase if a row exist containing a unique field (ID) value or not.

What I want to do is: If the row does not exist then I want to add it and if it exist then I want to do nothing but still add the ones that does not exist.

How to do that?
