Answer 1

I found that using either form-data or application/x-www-form-urlencoded works fine. The most important is the code you get from redirect uri is only used by one request. It means you could request the access token once for the code. If the you request more than one time with same code, you'll get the error like this:

{
    code: 400,
    error_type: "OAuthException",
    error_message: "Matching code was not found or was already used."
}

Wish you all the best ;)
