Resource description¶

The invoice resource contains the following public fields:

Field	Type	Description
number	string	Invoice number (with prefix)
order	string	Order code of the order this invoice belongs to
is_cancellation	boolean	`true`, if this invoice is the cancellation of a different invoice.
invoice_from	string	Sender address
invoice_to	string	Receiver address
date	date	Invoice date
refers	string	Invoice number of an invoice this invoice refers to (for example a cancellation refers to the invoice it cancels) or `null`.
locale	string	Invoice locale
introductory_text	string	Text to be printed above the product list
additional_text	string	Text to be printed below the product list
payment_provider_text	string	Text to be printed below the product list with payment information
footer_text	string	Text to be printed in the page footer area
lines	list of objects	The actual invoice contents
├ description	string	Text representing the invoice line (e.g. product name)
├ gross_value	money (string)	Price including taxes
├ tax_value	money (string)	Tax amount included
├ tax_name	string	Name of used tax rate (e.g. “VAT”)
└ tax_rate	decimal (string)	Used tax rate
foreign_currency_display	string	If the invoice should also show the total and tax amount in a different currency, this contains the currency code (`null` otherwise).
foreign_currency_rate	decimal (string)	If `foreign_currency_rate` is set and the system knows the exchange rate to the event currency at invoicing time, it is stored here.
foreign_currency_rate_date	date	If `foreign_currency_rate` is set, this signifies the date at which the currency rate was obtained.
internal_reference	string	Customer’s reference to be printed on the invoice.

Changed in version 1.6: The attribute invoice_no has been dropped in favor of number which includes the number including the prefix, since the prefix can now vary. Also, invoices now need to be identified by their number instead of the raw number.

Changed in version 1.7: The attributes lines.tax_name, foreign_currency_display, foreign_currency_rate, and foreign_currency_rate_date have been added.

Changed in version 1.9: The attribute internal_reference has been added.
