Anyone know if it is possible to tie into the IS API through an Android or IOS app?

Anyone know if it is possible to tie into the IS API through an Android or IOS app? What I’d like to do is have an app built that users can execute from their cell or tablet. I would like them to be able to make purchases, book appointments, tagging, populate custom fields etc. Essentially, would it be possible to tie into the API as deeply as Memberium does for WP? Thanks in advance

You would want to have a separate backend service for your mobile applications, as you would not want to deploy your Infusionsoft key/secret as part of your package.

On initially opening your mobile application, you would present the user with the OAuth webview, redirecting to your backend service to persist their tokens for use in retrieving data from Infusionsoft.
