I found this answer from 2018 and was wondering if there is any other way to store data on a slack workspace? I've read through the slack api documentation and still have not found any way to access a slack storage database.
Currently I am using Firebase as my db solution, but preferably I would want to store it to the workspace.
The is no slack storage/database.
The best you can do is upload files on slack.
https://api.slack.com/methods/files.upload
But this doesn't seem to solve the purpose you want it for.
