Update

PUT /:document-type/:document-id.json

Updates an invoice, simplified_invoice, invoice_receipt, credit_note or debit_note.

Creating new clients or items along with the invoice

This method also allows to create a new client and/or new items in the same request with the following behavior:

  • If the client name does not exist a new one is created.
  • If items do not exist with the given names, new ones will be created.
  • If item name already exists, the item is updated with the new values.

Taxes

Regarding item taxes, if the tax name is not found, no tax will be applied to that item. Be careful when updating the document items, any missing items from the original document will be deleted.
