To integrate Gist (formerly ConvertFox) as a helpdesk provider (to enable you to provide ticketing and chat capabilities within your HelpShelf widget) you will need to set the App ID.
First, you'll need to login to your Gust account by heading to https://app.getgist.com/users/sign_in. Once logged in, your App ID can be found in the URL in your browser.
In the screenshot we've circled the part that represents the App ID for this example project within Gist - which is muwisxnc
Copy this code and enter that into your HelpShelf setup form in the App ID field.
You should now be setup :)
Please don't forget to remove the original Javascript code you installed on your site for this provider. HelpShelf automatically loads this for you so you don't need to load it manually yourself as well. Doing so will cause issues. If you passed custom settings or user properties to this provider via the original Javascript code and you are not sure whether they will be carried through to your HelpShelf setup, then please contact us.
