Lua Requires Chilkat v9.5.0.64+

Xero Get File Content (Files API)

Demonstrates how to download the content of a Xero file. Lua

local chilkat = require("chilkat")

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

local rest = chilkat.Rest.new()

-- 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..
