Twitter Identity Provider
Overview
Adding a Login with Twitter button to FusionAuth is simple, and this guide will walk you through the steps necessary to collect the credentials from Twitter in order to enable this Social login.
Once you have completed this configuration you will be able to enable the Twitter login button for one or more FusionAuth Applications. Below is an example login page with the Twitter Identity Provider enabled.

Create a Twitter Account
Ensure you have a Twitter account, and then navigate to the Twitter Developer dashboard.
If you do not yet have a developer account, you will need to apply for access to the Twitter API.
Once you have logged into Twitter and have obtained access to a Twitter developer account, continue to the next step.
Create a Twitter App
If you do not yet have a Twitter app you will need to create an app in this step. If you already have a Twitter app that you plan to use for FusionAuth please review this section anyway to ensure your configuration is correct to support the Twitter login.
In the following screenshot you will find an example of the Create an App process. Review the following sections to ensure your configuration is correct. Fill out any required fields found on this form and click the Create
button to create a new Twitter app.
Enable Sign in with Twitter
Ensure that you check Enable Sign in with Twitter
checkbox. If this is not checked the Twitter login will not function properly in FusionAuth.
Add the Callback URL
In this example I have registered https://login.piedpiper.com/oauth2/callback
as the callback URL.
The first part of that value will be equal to the public URL of FusionAuth, in this case https://login.piedpiper.com
. The second part, the actual redirect URI will always be /oauth2/callback
.

Configure Permissions
Now you should have a Twitter app created, select the Permissions
tab and click the Edit
button in the top right of the panel.
You may select Read-only
in the Access permission
section and under Additional permissions
ensure you have checked Request email address from users
. An email address is required to complete login in FusionAuth.
If you will be using this Twitter app for other purposes, you may need more than Read-only
permission, but for the purposes of configuring this Twitter App for FusionAuth only Read-only
is required.
Click Save
once you have completed these changes.

Keys and token
Now click on the Keys and tokens
tab, in this section you will find the Consumer API keys. These two values will be used to configure the FusionAuth Identity Provider.
There is no further configuration to perform on this panel, you will only need to record or copy these values for the next step.

Create a Twitter Identity Provider
The last step will be to create a Twitter Identity Provider in FusionAuth. To create an Identity Provider navigate to Add provider
and select Twitter
from the dialog.
This will take you to the Add Twitter
panel, and you’ll fill out the Consumer key
and Consumer secret
required fields using the values found in the Twitter App Keys and tokens
tab from the previous step. The button text is also required but it will be defaulted to Login with Twitter
, you may optionally modify this default value.
To enable this identity provider for an application, find your application name in the Applications
configuration section at the bottom of this panel. You will always see the FusionAuth
application, this application represents the FusionAuth administrative user interface. If you wish to be able to log into FusionAuth with this provider, you may enable this application.
In the following screenshot you will see that we have enabled this login provider for the Pied Piper
application and enabled Create registration
. Enabling create registration means that a user does not need to be manually registered for the application prior to using this login provider.
For example, when a new user attempts to log into Pied Piper
using Twitter, if their user does not exist in FusionAuth it will be created dynamically, and if the Create registration
toggle has been enabled, the user will also be registered for Pied Piper
and assigned any default roles assigned by the application.
If you do not wish to automatically provision a user for this Application when logging in with Twitter, leave Create registration
off. You will need to manually register a user for this application before they may Sign in with Twitter
.
That’s it, now the Sign in with Twitter
button will show up on the login page for the Pied Piper application.

Proxy details
If you are running FusionAuth behind a proxy of some sort, please review the following information.
FusionAuth will detect the public URL of your instance at runtime to send to Twitter as the callback URL. If you are behind a proxy, ensure that the X-Forwarded-Host
and the X-Forwarded-Proto
headers are added by your proxy if the host or protocol do not match what is behind the proxy. For example, if your public URL is using https
and your proxy is performing SSL acceleration the URL behind the proxy may be http
. In this scenario, most proxies will have added the X-Forwarded-Proto
header to the request which will allow FusionAuth to send the correct URL to Twitter.
Building Your Own Integration
If you are building your own login experience, you’ll want to start the identity provider flow yourself and then complete the login.
You might do this if you are using the Login API rather than using the hosted FusionAuth login pages.
Completing the login is documented further in the API.
