An example Application for Windows Mobile that uses the AccountRight Live API.

This sample also demonstrates how to download and upload photos which are available on the Contact and Item resources.

To demonstrate how to handle the authorisation process with the assistance of the AccountRight Live API SDK i.e. handling the process where a user allows your application to access their MYOB Company File data hosted "in the cloud".

Before running this application on a device or emulator it is necessary to register an application (use http://desktop as the Redirect URL) and then amend the supplied client_id and client_secret in the Configuration.cs file.

It is assumed the developer examining this code is familiar with .NET development on the windows phone platform, however the ideas tested here can be easily transferred to other platforms.

This is not a full application and may require extra error handling to make it production ready; contributions from the community will be accepted.

First it is necessary to get the user to grant your application access to their data, this process eventually leads you to a stage where you will have a OAuth token that can be used to access the AccountRight Live API (see http://developer.myob.com/docs/read/getting_started/Authentication).

The sample application uses a hosted browser to extract a code from the returned HTML once the user has granted your application access to their data (see OAuthLogin_Navigated in MainPage.xaml.cs.)

To make the login screen render correctly on WP8 it is necessary to inject some JavaScript when navigating to https://secure.myob.com/oauth2/account/authorize

OAuthLogin.InvokeScript("eval",
    "var msViewportStyle = document.createElement(\"style\");" +
    "msViewportStyle.appendChild(document.createTextNode(\"@-ms-viewport{width:auto!important}\"));" +
    "document.getElementsByTagName(\"head\")[0].appendChild(msViewportStyle);");

as detailed in this issue twbs/bootstrap#9162

Once you have a code it it necessary to use that code to fetch an OAuth token that you can use to make requests to the users company files.

This is done using the AccountRight Live API SDK and the OAuthService which makes a request to https://secure.myob.com/oauth2/v1/authorize as detailed in the Authentication documentation.)

Now that we are in possession of an OAuth Token we can use this token to make requests against the AccountRight Live API.

We recommend that when accessing the API that you attempt to use compression in your requests to improve performance and to reduce the data delivered to your clients; this is especially important on mobile devices where bandwidth and data download limits apply. Use the header Accept-Encoding set to gzip in your requests and check for the header Content-Encoding set to gzip in the response.
