App Setup: Yahoo! Connection

Site owners need to create a 'web application' at Yahoo developer portal first:

https://developer.yahoo.com/apps/create/

On the Create App page:

• Select Application type as "Web Application".
• Redirect URI(s): It may appear tricky few times, as it may land to a not-so-friendly invalid parameter warning page just stating something like: Uh Oh! Looks like something went wrong, please try again later. To deal with this it is recommended to apply 2 separate Redirect URIs: https://yoursite.com/member.php as well as https://yoursite.com/member.php?action=login&gateway=yahoo
• Select API Permissions: "OpenID Connect Permissions" and check both boxes "Email" and "Profile" below

Sample app screen should be like:

Now grab the provided Client ID and Client Secret and add it to your MyBB Isango plugin settings, hit "Save" button and you are done!
