Can id values on files and folders can ever change once the file has been created? And are those values guaranteed to be unique?

 

I am currently writing an integration between box and a web portal, specifically to allow users to download documents uploaded into box via another system.

 

Right now my process is: 

1. Search for file using filename
2. Validate that the file is correct.
3. Download the file. 

What I would like to do is call steps 1 & 2, and then store off the file id. That way if a user calls download later, I can just specify the file id to download, instead of needing to search. This only works if the id doesn't change though. 

 

Thanks!

   File and Folder IDs are guaranteed to be unique and do not change over the item's lifetime — you're definitely okay to store those IDs and use them later to access the items.

  Hi ,

  You're correct that file and folder ID's never change. Once created, it has a unique ID that does not change despite moving it, renaming it or adding more content to the folder. Hope that helps your query!
