title: Xero API - Do Tax Rates have a Primary Key?
body: <p>I'm trying to pull Tax Rate records from our Xero platform to our external app (so that user can apply the tax rates to invoice line items in the external app).</p>
  
  <p>In order to keep those records up to date, I would usually rely on a Xero ID or other unique identifier. However with Tax Rates it seems they only identifier is the name (which obviously causes issues when a user updates a tax rate's name, or in the case of rates with matching names).</p>
  
  <p>Am I missing a distinct primary key I can use?</p>
