Configuring Sign-In with Twitter

To use sign-in integrations with Twitter, you must create a Twitter app and API credentials.

  • WHMCS’s integration uses Twitter API v1.1. Some Twitter accounts will require Elevated access to use this version of the Twitter API.
  • You can integrate using your existing Twitter accounts. Users will only see the app name that you define. They will not see anything relating to the account that you use to create the app.
You can’t change the Twitter account under which you create the app without requiring users to reauthenticate and re-link their accounts.

To configure sign-in using Twitter on your WHMCS installation:

1. Create a Twitter App.

To create a Twitter app:

  1. Log in to your Twitter account.
  2. Go to the Twitter Developer Portal.
  3. Click Projects & Apps.
  4. In the left sidebar, click Overview.
  5. Click Create App.

2. Save the app credentials.

To save the app credentials:

  1. Enter an app name.
  2. Save the displayed API key and API secret key.

3. Configure callback URLs.

To configure OAuth settings and callback URLs:

  1. In the app settings, click Set Up under User Authentication Settings.
  2. Enable OAuth 2.0.
  3. Set Type of App to Web App.
  4. Enter the URL for your Client Area as the callback URL and website URL.
    • You must enter a valid callback URL.
    • We recommend adding all three possible callback URLs, replacing http://example.com/whmcs/ with your WHMCS installation URL:
      • http://example.com/whmcs/index.php
      • http://example.com/whmcs/index.php/auth/provider/twitter_oauth/callback
      • http://example.com/whmcs/auth/provider/twitter_oauth/callback
  5. Click Save.

4. Configure the App in WHMCS.

To enable sign-in integrations with Twitter in your WHMCS installation:

  1. Log in to the WHMCS Admin Area.
  2. Go to Configuration () > System Settings > Sign-In Integrations.
  3. Select Activate under Twitter.
  4. Enter your Twitter API Key for ConsumerKey and the API Secret for ConsumerSecret.
  5. Click Save & Activate.

WHMCS will attempt to validate and test the details that you have entered. If the credentials are valid and successfully authenticate with the Google API, the system will save them.
