OAuth :

• App-only (AppOnlyAuth)
• SingleUserAuth
• PKCE (PKCEAuth)
• 3-legged (ThreeLeggedAuth)
• Pin-based (PinBasedAuth)

Request :

• RequestBuilder
• OAuthRequestBuilder

Samples

App-Only

var auth = new AppOnlyAuth
{
    ConsumerKey = AppCredentials.ConsumerKey,
    ConsumerSecret = AppCredentials.ConsumerSecret
};

SingleUserAuth

var auth = new SingleUserAuth
{
    ConsumerKey = AppCredentials.ConsumerKey,
    ConsumerSecret = AppCredentials.ConsumerSecret,
    AccessToken = AppCredentials.AccessToken,
    AccessTokenSecret = AppCredentials.AccessTokenSecret
};

PKCE (PKCEAuth)

var auth = new PKCEAuth
{
    ClientID = AppCredentials.ClientID,
    ClientSecret = AppCredentials.ClientSecret,
    RedirectUri = AppCredentials.RedirectUri,
    Scopes = Scope.AllScopes,
    State = "state"
};

3-legged (ThreeLeggedAuth)

var auth = new ThreeLeggedAuth
{
    ConsumerKey = AppCredentials.ConsumerKey,
    ConsumerSecret = AppCredentials.ConsumerSecret,
    CallbackUrl = AppCredentials.RedirectUri
};

Pin-based (PinBasedAuth)

var auth = new PinBasedAuth
{
    ConsumerKey = AppCredentials.ConsumerKey,
    ConsumerSecret = AppCredentials.ConsumerSecret,
    CallbackUrl = AppCredentials.RedirectUri,
    GetPin = () =>
    {
        Console.Write("Enter the PIN number:");
        return Console.ReadLine() ?? string.Empty;
    }
};

Authorize

auth.Authorize();

Or async

await auth.AuthorizeAsync();

GenerateAuthorizationString Sample with RequestBuilder

var auth = new SingleUserAuth
{
    ConsumerKey = AppCredentials.ConsumerKey,
    ConsumerSecret = AppCredentials.ConsumerSecret,
    AccessToken = AppCredentials.AccessToken,
    AccessTokenSecret = AppCredentials.AccessTokenSecret
};

var request = new RequestBuilder("GET", "https://api.twitter.com/2/users/by/username/twitterdev");

var authorizationString = auth.GenerateAuthorizationString("GET", "https://api.twitter.com/2/users/by/username/twitterdev");
request.AddHeader("Authorization", authorizationString);

var responseString = request.Send();

OAuthRequestBuilder (Call automatically Authorize if required by default and GenerateAuthorizationString)

var request = new OAuthRequestBuilder(auth, "GET", "https://api.twitter.com/2/users/by/username/twitterdev");

request.AddQueryParameter("expansions", "pinned_tweet_id");
request.AddQueryParameter("tweet.fields", "attachments,author_id,context_annotations,conversation_id,created_at,edit_controls,entities,geo,id,in_reply_to_user_id,lang,non_public_metrics,public_metrics,organic_metrics,promoted_metrics,possibly_sensitive,referenced_tweets,reply_settings,source,text,withheld");
request.AddQueryParameter("user.fields", "created_at,description,entities,id,location,name,pinned_tweet_id,profile_image_url,protected,public_metrics,url,username,verified,verified_type,withheld");

var responseString = request.Send();

Or async

var responseString = await request.SendAsync();

UWP Application

var auth = new ThreeLeggedAuth
{
    ConsumerKey = ConsumerKey,
    ConsumerSecret = ConsumerSecret,
    CallbackUrl = RedirectUri,
};

await auth.GetRequestTokenAsync(auth.CallbackUrl);

var url = auth.PrepareAuthorizationUrl();
var authenticationResult =
    await WebAuthenticationBroker.AuthenticateAsync(WebAuthenticationOptions.None, new Uri(url), new Uri(auth.CallbackUrl));
if (authenticationResult.ResponseStatus == WebAuthenticationStatus.Success)
{
    var paramaters = auth.ParseParametersFromResponseUrl(authenticationResult.ResponseData);
    await auth.GetAccessTokenAsync(paramaters);
}
