Ninox - Update Table

Hi guys, I´m struggling with the following problem:

I´m fetching data per Basic Auth request and put it into a ninox table. The data is getting updated on a regular basis, so I´d like to check for changes and put new data into the ninox table.

So far my scenario looks like this

The result right now is that the rows in the ninox table are getting filled with duplicates of every data entry.

I´d be glad if someone could help me out :slight_smile:
