Unable to fetch metadata of shared folder

Hi,

after creating a shared folder via endpoint 

https://api.dropboxapi.com/2/files/create_folder_v2

a folder id in the form "id:xxxxxxxxxxxxxxx" is returned.

When trying to fetch the metadata of this particular folder later on using the endpoint

https://api.dropboxapi.com/2/sharing/get_folder_metadata

and that very id, I receive an error response that the id is invalid.

The documentation/example of above endpoint has been updated recently, now using folder ids in the form "0000000" (numeric only).

So, how can I access the metadata of a folder having an id in the form of "id:xxxxxxxxxxxxxxx"?

Thank you very much in advance.

Best,

Jan
