(JavaScript) PayPal - Delete Draft Invoice

Deletes a draft invoice, by ID. Note that this call works for invoices in the draft state only. For invoices that have already been sent, you can cancel the invoice.

Note: This example requires Chilkat v9.5.0.65 or greater.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

// Note: Requires Chilkat v9.5.0.65 or greater.

// This requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// A single REST object, once connected, can be used for many PayPal REST API calls.
