Xero API Integration (https://developer.xero.com/documentation/api/api-overview/)
I have build a sample prototype to export (in CSV format) your Xero Invoice , contacts , accounts in one click. This prototype application using Xero Public application. You can easily convert your Xero public application to partner/private one .
