Delete Invoice from Xero

Question

I'm trying to delete an invoice from Xero by updating its status to "DELETED". Following the xeroizer github page I have tried the following:

xero = XeroApp.find_by(business_id: 270);
invoice = xero.find_invoice_by_ref(372).first
delete_invoice = xero.xero_client.Invoice.build(id: invoice.id, status: 'DELETED')
delete_invoice.save #=> false
delete_invoice.status #=> "AUTHORISED"

Unfortunately this doesn't update the invoice status. I thought that maybe removing the corresponding payment may help but it didn't. Incidentally I used a similar approach for removing the payment as above which did work.

Response to delete_invoice.save is:

Use the methods outlined in the api here:

https://github.com/waynerobinson/xeroizer/blob/master/lib/xeroizer/models/invoice.rb

For this question: After retrieving the invoice use invoice.void!.
