Context:
We are a company specialized in tailoring and i used a Google Sheet to reference all of our stock.
I was recently tasked to make a bare-codes system, surprisingly successfully, so that a client just have to scan with his phone to complete our order-sheet.
I am looking for a way to make a “secret page” on my site, only for the staff, that would search refs in a google sheet from a bare-code, then permit the modification of the sheet values… any idea how to do this?
Thanks in advance.
