How to fetch all apps across the Admin user account and their share permission data through APIs?

Hi Team,

While exploring the Quickbase application i want to fetch the application data across the Admin User account including all the applications that are created by other users of the account.

Being Super Admin I am able to see the applications of the other users from UI in the Admin console. I want to fetch this information through the API, while I am unable to find the REST API that fetches this data, is there any REST API available that fetches list of all application across the user account including the other user's apps.

I tried using the XML based  API and found that the API_GrantedDBs  gives the apps created by the Super Admin user but was unable to give the other user's application in the list.  How can I find the list of all applications across the user account including the other user's app. I am using the authorization ticket that is required to call the API. Please guide me for the same.

I also require to find the users and groups that have access to the apps through the APIs. 

Please help me in finding the above points, if the APIs are not available is there any another workaround to get this data?

Thanks.
