Twitter defines its platform as "what's happening in the world and what people are talking about right now."

You've got to be on Twitter to understand the strength of this statement. According to the company's Q3 2020 report, 187 million people use the platform daily and 330 million use it at least once a month.

The amount of data that can be generated by such a large population is enough to make any forward-thinking marketer interested in accessing Twitter's API.

Luckily, that's not impossible, nor is it difficult. However, to maximize the use of it, you have to understand how to apply these insights to your business.

But first, it’s worth understanding why marketers are so interested in accessing the Twitter API.

The Twitter API lets you read and write Twitter data. Thus, you can use it to compose tweets, read profiles, and access your followers’ data and a high volume of tweets on particular subjects in specific locations.

This bridges the gap between the two applications (the one on your phone and the company's software) while providing an extra layer of security. For instance, whenever you use a social media application, you interact with an API. Without direct contact between each other, any potential threats posed by one to the other are abated.

An API also provides a list of commands that can be executed. To use a popular analogy, imagine you're ordering food at a restaurant. You're at the table, ordering from the kitchen. The link between you and the kitchen is the waiter who ensures that the kitchen staff gets all the orders and meals are delivered to the right customers. You're also free to ask them what's available before making your order.

Without the waiter, you'd be pushing your way into the kitchen yourself, trying to get something to eat. That’s where the API plays its role as the middle man between two pieces of software.

The API provides a list of methods the two applications can use to communicate. They include:

As an example, let’s take a look at the methods you would use to post, retrieve, and engage with Tweets. 

The Twitter API uses two HTTP methods for retrieving Tweet data: GET and POST.

Be careful: these endpoints will look different depending on what you want to do, so be sure to check the documentation.

For example, if you want to retrieve a Tweet timeline, the endpoints will look as follows:

Aside from the endpoints, let’s take a look at some of the salient features of Twitter's API:

The Twitter API comes in three subscription packages: Standard, Premium, and Enterprise. Standard is completely free and comes with all the features you need to start using the Twitter API. 

If you’re looking for more functionality, such as access to Twitter’s full archive, you’d want to go for a Premium subscription. The Enterprise tier is best for those who want to use Twitter data to offer campaign management or Twitter management services to other businesses. 

You can do a wide variety of things that relate to retrieving, viewing, sorting, and filtering any data on Twitter. 

For example, you can: 

Ready to get started? Let’s go over how you can use Twitter’s API step-by-step. 

Here’s what this process looks like, in detail:

Before installing anything, make sure you're familiar with how to open a terminal.

On Mac: Go to Finder > Applications > Utilities > Terminal. Alternatively, open Spotlight by pressing CMD + Space and search for "terminal".

On Windows: Open Command Prompt by going to Start and searching for "cmd".

Microsoft stopped mainstream support for Windows 7 in January 2020. But if you're on that or older, use Start > All Programs > Accessories > Command Prompt.

To proceed, you need to have a Twitter developer account. To create one, open the apps management page and create an app. Name it, enter a website URL, and give a 100-word description.

To run Twurl, you'll need Ruby. So, make sure to have it installed. Then, follow Twitter's tutorials to install Twurl.

To send API calls, Twitter assigns a unique set of keys to your developer account. To access them, login to your developer account and select Details from your apps management screen.

Click on Keys and Tokens to generate a new, unique, and secret API key. Copy the secret and consumer API keys.

Run the following command in your terminal to authorize your Twitter app and account:

Note: replace and with your API keys.

Finally, copy and paste the returned URL to your browser to get a PIN. Then, enter the PIN into your terminal.

You're all set now. For more information, check out Twitter's guidelines on authentication.

Once you access the Twitter API, you'll be able to perform user activities, such as sending messages and media without having to open the application. By using command-line tools like Twurl and cURL, you’ll find more efficiency than you would by using the application directly.

Using a command-line tool, you can use your access to the Twitter API to perform a wide range of tasks. Twurl is one of the best tools for this job. It's built like cURL but has been modified specifically for the Twitter API.

Run the twurl -h command to learn more about using Twurl. For a simple tutorial, run twurl -T or twurl --tutorial.

Then, when you’re ready, below are some ideas for how to use the Twitter API.

You can use your new set up to send a tweet using the statuses/update POST endpoint. Twitter’s documentation says this "updates the authenticating current user's status" (i.e. sends a tweet).

Using Twurl, you can also upload:

Use the media/upload endpoint as follows:

To respond to a tweet, use the status/update POST endpoint, just as you would to send a fresh tweet.

To retrieve all tweets with a specific hashtag, use the search/tweets GET endpoint. By default, the results return tweets sent in the previous seven days.

You can use this function to evaluate a past marketing campaign — yours or that of another company. With access to all the tweets shared under a particular hashtag, you can learn a lot about your target audience, including the general mood around the topic.

Find out what people in your locale are buzzing about. Use the trends/place GET endpoint. You'll need to provide the Yahoo! Where On Earth ID (WOEID) for your location — use WOEID Lookup to find yours.

Once you know the trending subjects for your audience, you can decide how to use the discussions to promote your brand.

If you want to venture deeper into the world of the Twitter API, you can use all of these and other endpoints to create bots. Then, they can share specific content, show live updates about a particular topic, and remind your staff and followers of an event — among other things.

Now, let’s take a look at some Twitter API examples so that you can see how it all applies in the real world.

TweetBot, created by Tapbots, uses Twitter’s API to provide a seamless, ad-free experience for Twitter users. The timeline is also chronological rather than algorithm-based, and you can make private notes on people’s profiles, a feature not currently offered by Twitter. 

TweetBot uses the following functionalities: 

TweetDeck once used to be a separate property from Twitter, but was acquired by the social media giant in 2011. While it’s inseparable from its parent brand, TweetDeck is worth mentioning because it uses the Twitter API to function as a dashboard with full functionality. 

What makes it different? You can see notifications, tweets, and trending topics all at the same time. Additionally, you can change the columns for a completely personalized experience. 

TweetDeck uses all of the Twitter API functionalities. You can publish Tweets, create collections, send DMs, and more through this web app.

These are only a few of the examples of real-world Twitter API use cases. Twitter also has a list of partners who use its APIs to offer Twitter marketing, analytics, and data management services. If you’re an agency or SaaS business, Twitter APIs could help you develop a new offering for your customers. 

You can use Twitter APIs to build an app that your customers will love or strengthen your Twitter engagement efforts. Overall, Twitter is a great place to communicate with and learn from your audience. With access to the Twitter API, you can finetune your marketing through in-depth customer (and even competitor) analysis.
