Xero Download Attachment for an Item (such as an Invoice)

See more Xero Examples

Demonstrates how to download a particular attachment for a particular Xero item. Rust

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

http.set_auth_token(&json_token.string_of("access_token").unwrap_or_default());

// Replace the value here with an actual tenant ID obtained from this example:
// Get Xero Tenant IDs

http.set_accept("application/json");

// The example to list Xero attachments shows how to get attachment information.
// Here's a sample JSON response obtained form listing attachments:
// Your application can get the AttachmentID's and filenames from it.
