Connecting to data source hosted on Dropbox

The documentation on their developer site is quite comperhansive https://www.dropbox.com/developers/documentation/http/documentation

As for some boilerplate code to get you going have a look at the snippet below for an example of geting folder listing.

let
    data = [    path= "/code",
                recursive=false,
                include_media_info=false,
                include_deleted=false,
                include_has_explicit_shared_members=false],
    header = [  #"Authorization"="Bearer ZZZZZZZZZZZ",
                #"Content-Type"= "application/json"],
    response = Web.Contents("https://api.dropboxapi.com/2/files/list_folder",[Content=Json.FromValue(data),Headers=header]),
    out = Json.Document(response,1252)
in
    out

The only setup that I had to do on the Dropbox site was to create an App in the developer space and then generate an access key, which by the way is ZZZZZZZZZZ in my snippet.
