PayPal - Delete Draft Invoice

See more PayPal Examples

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.

Rust

// 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.

// Load our previously obtained access token. (see PayPal OAuth2 Access Token)
let json_token = chilkat::JsonObject::new();
let _ = json_token.load_file("qa_data/tokens/paypal.json");

// Build the Authorization request header field value.
let sb_auth = chilkat::StringBuilder::new();
// token_type should be "Bearer"
let _ = sb_auth.append(&json_token.string_of("token_type").unwrap_or_default());
let _ = sb_auth.append(" ");
let _ = sb_auth.append(&json_token.string_of("access_token").unwrap_or_default());

// Make the initial connection.
// A single REST object, once connected, can be used for many PayPal REST API calls.
// The auto-reconnect indicates that if the already-established HTTPS connection is closed,
// then it will be automatically re-established as needed.

// ----------------------------------------------------------------------------------------------
// The code above this comment could be placed inside a function/subroutine within the application

// the app may send many requests..
