Configure Twitter as a Federated Authenticator

This page guides you through configuring Twitter as a federated authenticator in WSO2 Identity Server.

Set up a Twitter app


You can skip this section if you have already registered your application on Twitter.

  1. Log in to using your Twitter credentials.

  2. Click Create project and set up your project.

    Create Twittter project

  3. In App Set Up, follow the steps given below.

    1. Select your preferred App Environment. Set Twittter app_env

    2. Set an App Name. Set Twittter app_name

    3. Take note of the client ID and client secret of the application. Set Twittter app_name

  4. Click App Settings at the bottom of the page.

  5. Click Set up under User Authentication Settings.


    1. Fill in the user authentication details with the following values.

      • Enabled OAuth 2.0
      • Type of app - Web app
      • Callback URI / Redirect URL - https://localhost:9443/commonauth
      • Website URL - Setup_user_authentication
    2. Click Save.

    3. The OAuth client key and secret presented by Twitter is not required in this flow.

You have now set up your Twitter application.

Register an identity provider

  1. Log in to the Management Console(https://<IS_HOST>:<PORT>/carbon) using admin/admin credentials.

  2. Navigate to Main > Identity > Identity Providers > Add.

  3. Enter an Identity Provider Name, Display Name, and Description.

  4. Expand Twitter Configuration under Federated Authenticators . twitter-config-federated-auth.png Fill in the following fields details according to the application created above.

    Field Description Sample Value
    Enable This option enables Twitter to be used as an authenticator for user provisioned to the WSO2 Identity Server. Checked
    Default This options sets the Twitter to be used as the default authentication mechanism. If you have already selected any other Identity Provider as the default federated authenticator, selecting this option deselects it. Checked
    API Key This is the consumer key generated at the Twitter application registration. wuerRmdgwlqX0oE1WNDdsh17o
    API Secret This is the consumer secret generated at the Twitter application registration.
    Callback URL

    This is the Callback URL you entered at the Twitter application registration. This is the URL to which the browser should be redirected after the authentication is successful.

    URL format: https://<host-name>:<port>/acs

    The acs indicates the Assertion Consumer Service URL of the WSO2 Identity Server endpoint that accepts the responses sent by Twitter.

  5. Click Register.

Configure the service provider

To register your application as a service provider in the WSO2 Identity Server:

  1. Log in to the WSO2 Identity Server Management Console using administrator credentials.

  2. Go to Main > Identity > Service Providers > Add.

  3. Enter a Service Provider Name. Optionally, enter a Description.

  4. Click Register.

  5. In the Inbound Authentication Configuration section, click Configure under the OAuth/OpenIDConnect Configuration section and set the configurations as required.

  6. Configure the Callback URL of the sample application (


  1. Keep the other configurations as default and click Add

  2. Click Register. Now you will be sent back to the Service Providers page.

  3. Take a copy of the OAuth Client Key and the OAuth Client Secret for later usages


  1. Go to the Local and Outbound Authentication Configuration section.

  2. For Authentication Type, select Federated Authentication and select the Identity Provider you created from the dropdown list under Federated Authentication.

  3. Click Update to save the changes.

You have now added and configured the service provider.

Try it

You have successfully configured Twitter as your federated authenticator. Now, when you try to log in to your application, it should redirect to the Twitter login page. On successful authentication with your Twitter credentials, you will be able to access your application.

Set up the sample app

  • Download Apache Tomcat 9.x from here and install. Tomcat server installation location will be referred as <TOMCAT_HOME> later in this guide.

  • It is recommended that you use a hostname that is not localhost to avoid browser errors. Modify the /etc/hosts entry in your machine to reflect this. Note that wso2is.local is used in this documentation as an example, but you must modify this when configuring the authenticators or connectors with this sample application.

  • Download the sample from GitHub.

    1. Navigate to WSO2 Identity Server Samples.
    2. Download the pickup-dispatch.war file from the latest release assets.

Deploy the sample app

Deploy this sample web app on a web container.

  1. Copy the pickup-dispatch.warfile into the webapps folder. For example, <TOMCAT_HOME>/apache-tomcat-<version>/webapps

  2. Open a terminal window and add the following entry to the /etc/hosts file of your machine to configure the hostname.   wso2is.local

    Why is this step needed?

    Some browsers do not allow you to create cookies for a naked hostname, such as localhost. Cookies are required when working with SSO . Therefore, to ensure that the SSO capabilities work as expected in this tutorial, you need to configure the etc/host file as explained in this step.

    The etc/host file is a read-only file. Therefore, you won't be able to edit it by opening the file via a text editor. Instead, edit the file using the terminal commands.
    For example, use the following command if you are working on a Mac/Linux environment.

    sudo nano /etc/hosts
  3. Open the file found in the <TOMCAT_HOME>/webapps/pickup-dispatch/WEB-INF/classes directory and edit the consumerKey and consumerSecret with the values obtained from the OAuth configuration.

  4. Restart the Tomcat server.

Log in

  1. To test the sample, go to the following URL: http://<TOMCAT_HOST>:<TOMCAT_PORT>/pickup-dispatch.
    For example.

Pickup-dispatch application

  1. Click the LOGIN button.

  2. You are redirected to the Twitter Login page. Enter your Twitter credentials and you will be taken to the home page of the pickup-dispatch app.
