Meet the new Glide Apps
Glide Pages are now Glide Apps. Please refer to this article for up-to-date information, as some of this documentation is outdated.
By default, all the screens in your app have the same URL, which makes it impossible to share a specific item in your app with someone.
However, if your table uses Row IDs, viewing a details screen will update the current URL, which is available as a value called Link to current screen.
You can Copy this link to the clipboard, send it to Zapier, or use the Share action to let your users easily share items in your app any way they'd like.
A note about Deep Links
Your Google Sheet needs a Row ID column for Deep Links to work. Alternatively, you can just use a Glide Table.
