400 - Parameters are messed up again? Refreshing Token

[Aresak]

When I send an POST request to the API, I receive an 400 error, but no more info like what is wrong.

The code:
Twitch::Post("https://api.twitch.tv/kraken/oauth2/token", array( "grant_type" => "refresh_token", "refresh_token" => Aresak::mysqli_result($result, $i, "extras"), "client_id" => Twitch::ClientID(), "client_secret" => Twitch::ClientSecret() ));

I guess there are messed up parameters again. Like client_id should be Client-ID etc., but I don’t know which are right as far as there is nothing in the documentation.

Do you log the request you make so you know your code is requesting the URL with the data in the format you’re expecting?

[Aresak]

Yes, I know it is correct.

Did you ever figure this out? I am getting “message”: “The parameter “grant_type” was malformed: value must be one of “authorization_code”, “password””. Is using the Refresh_Token not supported? Then why make OAuth tokens invalid after 240 minutes?

Did you correctly follow the documentation:

Authentication

To refresh, use this request:

curl -X POST https://api.twitch.tv/kraken/oauth2/token 
    --data-urlencode
    ?grant_type=refresh_token
    &refresh_token=<your refresh token>
    &client_id=<your client ID>
    &client_secret=<your client secret>

Sounds like you have performed a GET request instead of a POST request
