Thanks for the details Samantha! The Dropbox API Explorer is built for Dropbox API apps, not Dropbox Business API apps, and there is one additional thing that is required for Business apps like yours that the Explorer doesn't do. Specifically, when calling non-team endpoints, such as /users/get_current_account, you need to specify an additional header to indicate which team member to act on. You can find the information on this here:
You can use the Explorer to build some sample code, but then you'll need to modify it to add the extra header and run it outside the Explorer.
We love to learn from the educators who use Dropbox. Whether you teach kids, teens, adults or a combination of all three, we want to know what apps and integrations you use with Dropbox to help with teaching. Which of the ones below is your favorite, or most used tool?
