I don't know what I do wrong, but everytime I tried to obtain the token (after user authentication of course), the result is always Invalid grant_type parameter or parameter missing
Possibly related to Box API always returns invalid grant_type parameter on obtaining access token
Here is my fiddler result:

Even following the curl example gives the same error. Any help would be appreciated.
Edit: tried with additional redirect_uri params but still the same error

Looks like Box requires a correct Content-Type: application/x-www-form-urlencoded request header in addition to properly URL encoding the parameters. The same seems to apply to refresh and revoke requests.
Also, per RFC 6749, the redirect_uri is only
REQUIRED, if the "redirect_uri" parameter was included in the authorization request as described in Section 4.1.1, and their values MUST be identical.
