Reference - Facebook SDK for JavaScript - Documentation - Meta for Developers
Facebook SDK for JavaScript - Reference Reference docs for each of the full list of methods and functions available in the SDK.
Core Methods
Method
Description
.init()
Used to initialize and setup the SDK. All other SDK methods must be called after this one.
.api()
Make an API call to the Graph API .
.ui()
Used to trigger different forms of Facebook created UI dialogs, such as the Feed dialog, or the Requests dialog.
Facebook Login Methods
Method
Description
.getLoginStatus()
Returns the Facebook Login status of a user, with an authResponse object if they are logged in.
.login()
Prompts a user to login to your app using the Login dialog in a popup. This method can also be used with an already logged-in user to request additional permissions from them.
.logout()
Used to logout the current user both from your site or app and from Facebook.com.
.getAuthResponse()
When your app is able to assume that a user is definitely logged-in via Facebook, this synchronous method can return the authResponse object without the overhead of an asynchronous call.
Event Handling Methods
Method
Description
.Event.subscribe()
Subscribe to a JavaScript event, which will fire on various different types of actions, such as someone clicking a Like button, or adding to a Comments Box.
.Event.unsubscribe()
Remove any event subscriptions that were previously created.
App Events This Facebook SDK (JS) App Events API has been deprecated and is no longer supported starting July 1, 2022. There are no plans to add new features to this product.
Instead of using FB.AppEvents.LogEvent, we recommend that you send these events through the Meta Pixel .
XFBML Methods XFBML is a markup language like HTML, with special tags that are used to insert social plugins into HTML pages.
Method
Description
.XFBML.parse()
Parses and renders any XFBML on a page. This can be useful if you insert any social plugins into the DOM after the initial page load, or you set xfbml as false in FB.init().
Canvas Methods These methods can only be used by Apps on Facebook.com that run in a Canvas page .
