Hi there,

I’m trying to send an invoice that I’ve just created using Xero. I’ve created it successfully, but when I test the Send Sales Invoice By Email In Xero step I get this error message “A validation exception occurred, Invoice id <INV-3416> is not valid”. I get this error whether I hard code the invoice number or look it up from the previous step where I created it. 

The invoice definitely exists; I just created it, I see it in Xero and I did a test Find Invoice In Xero step just before the email one and it finds it no problem. 

The Send Sales Invoice By Email In Xero step does say “To email an invoice, it must have a status of Awaiting Approval, Awaiting Payment or Paid.” and this is the case. The status in Xero of this invoice is very clearly “Awaiting Payment”.

The Send Sales Invoice By Email In Xero step does let me select specific invoices that it has found, but this only shows me what appears to be the oldest 100 or so invoices, which look like they’re all paid. 

I’ve even managed to send it by manually finding the invoice in Xero and triggering it there. Its just automating it through Zapier that’s eluding me. 

Does anyone have any idea why this invoice wouldn’t be valid? As far as I can see, the only valid invoices that I could send are these really old ones, which defeats the point. I want to create an invoice and then send it to the customer. 

Alternatively, does anyone have any good ideas for a workaround? I can’t see a way to download the invoice and then send it via attachment or something else. 

Thanks!
