HI Evan,
Thanks for your response.
I've found a solution using Zapier - but suspect pipelines would work too.
Basically, I've created a table in Quickbase where the key is the S3 file key (filename and path).
Zapier populates this table whenever a file is uploaded to S3.
My main table then joins to this S3 files table using the key (which is determined programatically based on the record ID) so if the file has been uploaded to S3, it will be in the table, and there will be a match.
I think this is broadly in line with what you were thinking.
From there it's easy, and it's working fine.
