Twitter API Twitter API Update Causing Sign-In Integration Errors

[WHMCS ChrisD]

Summary:

Twitter have made some changes to their API this week which impacts our WHMCS Sign-In Integrations. More information on the changes Twitter have made are outlined on their community.

In essence, we can no-longer override the Callback URL used by the Twitter App. Instead the Callback URLs settings on the Twitter Developer site now act more like a whitelist. The Callback URL sent by WHMCS must match exactly with the Callback URL specified in the app settings, or the login will fail.

Error presents as:

In WHMCS this manifests itself as an error when attempting to login with Twitter:

We were unable to connect your account. Please contact your system administrator

 

Or when activating Twitter sign-in for the first time in the admin area:

Invalid details not saved. Please verify your details and try again

 

Resolution:

Because the Callback URL can take several forms, depending upon the Friendly URLs setting, we  are recommending users configure all three in their Twitter app settings.

1. Visit https://apps.twitter.com/ 
    
2. If not logged in, login to your Twitter account
    
3. Select your WHMCS sign-in app from the list
    
4. Click the Settings tab
    
5. In the Callback URLs section, replace the current single entry with the following three entries:
    
   1. http://demo.whmcs.com/whmcs/index.php?rp=/auth/provider/twitter_oauth/callback
   2. http://demo.whmcs.com/whmcs/index.php/auth/provider/twitter_oauth/callback
   3. http:///demo.whmcs.com/whmcs/auth/provider/twitter_oauth/callback
      
      Remember to replace http://demo.whmcs.com/whmcs/ with the actual URL of your WHMCS installation
       
6. Click Save Changes
