hello, I just created an application and I want to ask how to make when someone creates new data but the data is already in the airtable, because the data is already in the airtable then there will be a notification that the data is already in the airtbale?

The same data will appear errors in the airtable

your choice… if you wanna compare the user input with only one colum then just that colum alone extract, or you can use this extension which will be convenient to use for this purpose…
