//! Bakong API - Check Transaction Example
//!
//! This example demonstrates how to check transaction status using MD5 hash.
//!
//! Prerequisites:
//! - Get a Bakong API token from https://api-bakong.nbc.gov.kh/
//! - Make a test payment to get a transaction MD5 hash
//!
//! Run with: BAKONG_TOKEN=your_token cargo run --example api_check_transaction --features rustls-tls
