I need to implement a function where user can check-in just informing his code (voucher). The procedure must be:
- User will access the app (public app, without login)
- User type the code (voucher) on the first screen and “send” this info
- A new screen is presented with the details of that voucher(name, dates, etc) and a button to confirm the check-in
I’m stuck on the step 2, how to search for the entered value on the sheet. Any advice?
