We use Xero Invoice Webhook to create the electronic invoices needed to comply with Argentina tax laws.

We have discovered some updates that could be made to the invoice webhook in order to dramatically decrease the API calls we send to Xero (to get the invoices details).I think this updates will also benefit the implementation of e-invoice in USA, AU and NZ.

The two updates are very simple. Just add to the invoice webhook payload the following data:
1 -invoice type (in order to avoid API call for bills)
2- nvoice status (in order to avoid API calls for draft and awaiting approval invoices)
