When your application requests public data, the request doesn't need to be authorized, but does need to be accompanied by an identifier, such as an API key.

Your application needs to identify itself every time it sends a request to the Google Knowledge Graph Search API, by including an API key with each request.

Acquiring and using an API key

To acquire an API key:

Open the Credentials page in the API Console.
This API supports two types of credentials. Create whichever credentials are appropriate for your project:
- OAuth 2.0: Whenever your application requests private user data, it must send an OAuth 2.0 token along with the request. Your application first sends a client ID and, possibly, a client secret to obtain a token. You can generate OAuth 2.0 credentials for web applications, service accounts, or installed applications.
  Note: Since this API doesn't have any methods that require OAuth 2.0 authorization, you might only need to obtain API keys, which are described below. However, if your application calls other APIs that require user authorization, then you still need OAuth 2.0 credentials.
  For more information, see the OAuth 2.0 documentation.
- API keys: A request that does not provide an OAuth 2.0 token must send an API key. The key identifies your project and provides API access, quota, and reports.
  The API supports several types of restrictions on API keys. If the API key that you need doesn't already exist, then create an API key in the Console by clicking Create credentials > API key. You can restrict the key before using it in production by clicking Restrict key and selecting one of the Restrictions.

To keep your API keys secure, follow the best practices for securely using API keys.

After you have an API key, your application can append the query parameter key=yourAPIKey to all request URLs.

The API key is safe for embedding in URLs; it doesn't need any encoding.

With nearly 2.9 billion global monthly active users, Facebook is the biggest social network worldwide.

Not only does that mean the platform has a built-in user base you could try to reach, but it also contains lots of information and functionality that might be useful to your app. For example, you could simplify the login process for your app by allowing users to log in using their Facebook credentials. Or you could enable your app to gather and send more refined data to the Facebook algorithm so you could better measure and optimize your Facebook ads.

These are just a few ways you can use a Facebook API to better serve your business and audience. Before we dive into all the ways you can use the API to advance your business goals and delight your customers, let's define what the Facebook API is and how to get started with it.

What is the Facebook API?

The Facebook Graph API is an HTTP-based API that allows developers to extract data and functionality from the Facebook platform. Applications can use this API to programmatically query data, post in pages and groups, and manage ads, among other tasks.

The other Facebook APIs are extensions of the Graph API. Let’s briefly describe them below.

Conversions API

The Conversions API allows apps to track web conversions, post-conversion events, and page visits as well as data required for ad targeting, ad reporting, audience insights, and dynamic ads. This information can help improve the performance and measurement of your Facebook ad campaigns.

Live Video API

The Live Video API enables apps to stream live video directly to Facebook user profiles, pages, and groups. With this API, your app can broadcast a live video stream, schedule broadcasts, interact with audiences during broadcasts, and create polls on broadcasts.

Instagram APIs

Instagram APIs allow your app users to publish media, moderate comments, discover @mentions, share their content as Instagram stories, get and manage published photos, videos, and stories, and more.

For more examples of how to use Instagram APIs, check out 11 Ways to Use Instagram’s API for Your Business [Examples].

Marketing API

The Marketing API enables businesses to better advertise on Facebook by automating ad management and creation, offering custom dashboards for insights and performance, and more.

Pages API

The Pages API allows apps to create and manage a Page’s settings and content. Using this API, an app can create and get Posts, get Comments on Page-owned content, get Page insights, update actions that Users are able to perform on a Page, and more.

Video API

The Video API allows apps to publish videos on Facebook Pages and Groups, cross post (ie. publish a video on multiple Pages without uploading the video to each Page), and get insights on those videos.

WhatsApp Business API

The WhatsApp Business API is designed to enable medium and large businesses to communicate with their customers at scale. Businesses can use this API to connect thousands of agents and bots to customers via WhatsApp programmatically and manually.

Now that we understand the variety of APIs that Facebook offers and what they do, let’s go over how to use them. The process of getting started with a Facebook API will depend on which API you’re using. Below we’ll outline the process for the Facebook Graph API.

How to Get Started with the Facebook API

To get started with the Facebook Graph API, you will need:

A Facebook Developer account
A Facebook App (with some basic information about your app provided in the App Dashboard)

If you already have these, it’s time to make your first request.

Step 1: Open the Graph Explorer tool in a new window.

First, open the Graph Explorer tool in a separate browser window.

In this new window, you’ll notice the explorer loads automatically with some information. From left to right, there’s a default query with the GET method, the latest version of the Graph API, and the /me node followed by the id and name fields. This information is circled in the screenshot below.

Step 2. Generate an access token.

Next, click the Generate Access Token button on the right hand side of the screen. A window will pop up prompting you to log in to Facebook. By logging in, you will be granting your app permission to get your name and profile picture from Facebook.

Click Continue as [username].

A User Access Token is created. This token contains information such as the app making the request, the person using the app to make a request, if the access token is still valid (it expires in about an hour), the expiration time, and the scope of data the app can request. In this request, the scope is public_profile which includes your name and profile picture.

To view this information, click the information circle icon next to the access token.

Step 3. Submit the request.

Click the Submit button in the upper right corner. You will see a JSON response with your Facebook User ID and name in the Response Window.

You can make subsequent requests more complicated by adding fields (like the email field) and any required permissions (like the email user data permission). By doing so, you will change the scope of the access token and need to create a new one.

To generate a new access token, follow the same steps above: click Generate Access Token, give your app permission to access your email by logging in to Facebook, and click Submit.

Now that you know how to access the Facebook Graph API, there's a lot you can do with it. Below are several ways to use the Graph API and its extensions.

1. Get page insights.

The Facebook Graph API is all about getting data into and out of Facebook. With this API, you can query data and create powerful dashboards to understand your content and audience better. For example, you can extract information from your own Page that shows who wrote each post and how many people liked it. Then, you can figure out what writers get the most likes.

2. Get audience insights.

You can also use the Facebook API to understand your audience better. For example, you can collect basic demographics on your visitors, which will ultimately help you provide a better product. That’s why Spotify and Amazon use the API.

3. Manage ads.

You can use the Facebook API to manage ads as well. For example, you can retrieve the creative content or ads of an ad account in a single request. You can also read and pull ads reports for ad accounts you own or have been granted access to by the account owner.

4. Provide customer support.

You want to respond to a customer’s message even if your business is closed for the weekend or you haven’t had time to resolve their issue yet. The Facebook API allows your app to have a human agent respond to user messages in cases where their issue cannot be resolved in the standard messaging window.

5. Post live videos.

The Facebook API allows users to post live videos to Pages, Groups, and User timelines from your app.

6. Embed Facebook and Instagram feeds.

You can use the Facebook API to embed public Facebook and Instagram pages, posts, and videos into your application. For example, you might display your Instagram feed on your blog, or embed a positive Facebook review from a customer on your ecommerce site.

7. Access and post content in Facebook Groups.

The Facebook API allows your app — and your app users — to access and manage content in their Facebook Group. With this API, you can let people publish content from your app to their Group. You can also help them get information about content posted to their Group, as well as get aggregated insights about activity happening in their Group.

8. Access content on Instagram.

The Facebook API allows your app to access Instagram Graph API's Hashtag Search endpoints. This, in turn, enables your app to discover photos and videos using your hashtags, understand public sentiment around your brand, and identify contest, competition, and sweepstakes entrants.

9. Gather competitive benchmark analysis.

With the Facebook API, you can access and read public data for Facebook Pages that you are not the admin of. This data, including business metadata, public comments, and posts, can be used for competitive analysis and benchmarking.
