When trying to list folder contents, error happens
Hello,
New to Dropbox API.
I can create folders and files, but when I try to list the contents of a folder, I get an error message. I'm particularly interested in getting the contents of...
I see you're supplying a folder path and not a shared link and are using app authentication on this /2/files/list_folder call, which can cause this 'path/unsupported_content_type' error.
When using app authentication, that is, with the app key and secret instead of an access token, you do not have access to an account directly. Using app authentication with /2/files/list_folder is instead meant for accessing the contents of a shared link.
So, you would need to either supply ashared_linkon the /2/files/list_folder call, or switch to using user authentication, that is, with an access token for an account.

Hello Greg!
Thanks for your help!!
I thought I had to use the type of authentication use in the documentation's example (as I recall reading somewhere else here), but I see now that using the token will do what I need. Thanks!
Hi Dropbox Team,
When I try to use API: /2/files/list_folder using App Authentication using my personal account it works successfully, but when I try same using my Company/Business account it gives following error:{"error_summary": "path/unsupported_content_type/..","error": {".tag": "path","path": {".tag": "unsupported_content_type"}}}
Could you please let us know why this difference is there?Also Dropbox documentation mentions we can use App Authentication as well, so why it is been restricted ?
Hi rohitkmk,
As Greg already mentioned, app authentication can be used for information that doesn't need access to particular account (either personal or business) - listing public accessible shared links or at most password protected (the one you can provide thorough the call parameter). App Authentication identifies the application itself, but not the user that uses it! That's why you cannot use App Authentication to access data closely related to any particular account (i.e. to user, again both neither personal nor business) in any way (here we assume no any shared link points to the content; a link that can be "workaround"). To list (or do something else to) any part of account content, you need to represent somehow user having access to that content. That's what different tokens (access token and refresh token) are used for - user authentication.
According to your description you are already using user authentication (most probably; and by mistake label it as app authentication). If so, just keep in mind that for individual accounts providing token identifies in unique way particular user (the only user), but in case of business account (team account) it identifies in unique way the team (not user) if you have selected one team scope at least. You can solve it by removing all team specific scopes from permissions of your application (if you don't need them) or explicitly point the user using 'Dropbox-API-Select-User' header - whatever better match your case.
Hope this helps.
PS: Just a recall - when you change permissions, you need to reauthenticate the user; such changes are NOT retroactive!
In any case post exact way you got to the error (like represented in OP).

rohitkmk I see Здравко already helpfully offered some guidance here, but if you're still having trouble with this, please feel free to share the relevant code/request that's failing with this error. Please be sure to redact any secret values, such as an app secret or access token though.
Hi @Greg,
Please find the details of issue I am facing with /2/files/list_folder API.
When I try to fetch the list of folders using this API, I only the list of folders I have created for my Apps (Apps created from Developer console). For e.g.:But other folders to which I have access in Dropbox (created by other team members or myself), they never appear in the List folder API response.
Should I ask my Team admin to create App in Developer console, use the client id and client secret(for Bearer token generation) of this App to call APIsso that I can get list of all folders and files created by the Team or do I need to have Administrator role for myself to fetch all these details?
Could you please guide?
