Upgrade Xero API on website from 1.0 to 2.0

Job ID: 32324244

Budget: $30 – $250 USD

Our website integrates with Xero cloud accounting software. We have not noticed but Auth1.0 has been discontinued and therefore our invoice generating has stopped.

We need someone to update and upgrade us to Auth 2.0.

Please only bid if you are fully aware of this process and have done it many times before.
Our original developer is unavailable therefore i will not be able to share much information on code and setup.

Please be clear as to what you will need access to and how long it will take.

this is an urgent request as our website is no longer generating invoices to clients.
