Rust Requires Chilkat v11.0.0+

Amazon Pay - Cancel Charge

See more Amazon Pay Examples

Moves Charge to Canceled state and releases any authorized payments. Rust

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

let http = chilkat::Http::new();

// Implements the following CURL command:

// curl "https://pay-api.amazon.com/:version/charges/:chargeId/cancel" \
// -X DELETE
// -H "authorization:Px2e5oHhQZ88vVhc0DO%2FsShHj8MDDg%3DEXAMPLESIGNATURE"
// -H "x-amz-pay-date:20201012T235046Z"
// -d '{
//     "cancellationReason": "REASON DESCRIPTION"
// }'

// Convert a cURL Command to HTTP Source Code
