Demonstrates how to download the content of a Xero file.

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

Chilkat Go Downloads Go Package for Windows, MacOS, Linux, Alpine Linux, Solaris

    // 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.

    rest := chilkat.NewRest()
    var success bool

    // 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..
