(C# UWP/WinRT) Xero Get File Content (Files API)

Demonstrates how to download the content of a Xero file.

Note: This example requires Chilkat v9.5.0.64 or greater.

Chilkat Universal Windows Platform (UWP) / WinRT Downloads Chilkat for the Universal Windows Platform (UWP)

// Note: Requires Chilkat v9.5.0.64 or greater.

// This requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

Chilkat.Rest rest = new Chilkat.Rest();
bool success;

// Before sending REST API calls, the REST object needs to be
// initialized for OAuth1.
// See Xero 2-Legged OAuth1 Setup for sample code.

// Assuming the REST object's OAuth1 authenticator is setup, and the initial
// connection was made, we may now send REST HTTP requests..
