Can we automate in a way where we can delate the duplicate entry in airtable on the basis of time stamp or the previous entry?
Welcome to the community, @Srishti_Jain! Airtable doesn’t offer any automation features itself. For a pseudo-automation approach, you could write a script in the Scripting block to look for duplicate entries. I seem to recall some threads along that line, which you could probably find with a quick search. For true automation, you could probably use Zapier or Integromat, though I don’t have experience building such a system, so I can’t say how complex it would be.
