How To Use the Twitter API with C# (.NET) [in 4 Easy Steps]

Before we begin, you’ll need to get access to Twitter API credentials.

If you haven’t already, you can learn how to do so here.

To summarize, you will need to sign up for a free Twitter account (if you don’t have one already) and create a new application at Twitter’s dev portal to get access.

Once you’ve received your credentials from the step above, head over to the Twitter API on RapidAPI.com and login (or register for a free account).

After you’ve logged in, you’ll need to fill out all the required fields before you can test the API.

For more details, you can view this tutorial.

Once you’ve successfully filled out all your Twitter API Key credentials, you should now be able to test the API, which produces a code snippet such as this:

From the dropdown of SDKs, select “C# (.NET)”

The Twitter API is also available in the following languages:

• Node.js
• PHP
• Python
• Ruby
• Objective-C
• Java (Android)
• cURL
• GO
• Elixir
• JavaScript

Here is the list of the 4 available API endpoints for the Twitter API:

1. retweet – This block allows you to retweet a certain tweet.
2. retweetEdit – This block allows you to retweet a certain tweet and to add additional text to it.
3. search – This block allows you to search for tweets.
4. tweet – This block allows you to tweet whatever status you like.

1. retweet

Required Fields

• tweetId – the ID of the tweet you want to retweet
• accessTokenKey – your Twitter access token key
• accessTokenSecret – your Twitter access token secret

Let’s try it with this tweet:

using RapidAPISDK;

private static RapidAPI RapidApi = new RapidAPI("XXXXX", *KEY*);


List body = new List();

body.Add(new DataParameter("consumerKey", "XXXXX"));
body.Add(new DataParameter("consumerSecret", "XXXXX"));

try { 
	Dictionary response = RapidApi.Call("Twitter", "retweet", body.ToArray()).Result;
	object payload;
	if (response.TryGetValue("success", out payload)){ 

	}
	else{ 

	} 
} 
catch (RapidAPIServerException e){ 

 }
catch (Exception e){ 

 }
