5.2. Retrieve Invoice List

Returns a paged list of Invoices. The invoices are sorted in descending order by dueDate. Either the internal CustomerId or the Customer Account Number (extCustomerRef) may be used to query for a single customer's invoices.

Defaults used if the query string parameters are missing:    offset=0

   max=50

   status = ignored if not defined

   customerId = ignored if not defined (i.e, returns a list of all customers)

   extCustomerRef = ignored if not defined (i.e, returns a list of all customers)

GET /rest/invoices?format=xml&offset=[n]&max=[m]&status=[status]&customerId=[id]

GET /rest/invoices?format=xml&offset=[n]&max=[m]&status=[status]&extCustomerRef=[customerNumber] 


Sample Output:

<list>

  <invoice id="1">

  ...

  </invoice>

  <invoice id="2">

  ...

  </invoice>

</list>

5.3 Cancel Invoice

While an Invoice cannot be deleted (for financial audit reasons), you may cancel an invoice that is in the "outstanding" status. This changes the status of the Invoice to Cancelled and reverses the invoice amount from the Customer's account balance. The REST calls for cancelling an invoice use the HTTP DELETE operation:

DELETE /rest/invoice/[id]?suspendOrders=true

DELETE /rest/invoice?invoiceNumber=[value]&suspendOrders=true
