Any way to obtain "simplified invoice" field from order API?


In Spain we are obliged to have the simplified invoice number printed on the ticket, we are now printing this using Square, however, I don’t seem to be able to access this field from the API. Any way to get it?
See the picture on this link, its called Factura Simplificada.


What’s the ID of the payment that you referenced in the image? :slightly_smiling_face:
