chip-sdk
Rust SDK for the CHIP payment gateway API.
Installation
Add to your Cargo.toml:
[dependencies]
chip-sdk = "0.1"
tokio = { version = "1", features = ["full"] }
Quick Start
use chip_sdk::model::{ClientDetails, Product, Purchase, PurchaseDetails};
use chip_sdk::ChipClient;
#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
let client = ChipClient::builder()
.base_url("https://gate.chip-in.asia/api/v1")
.bearer_token("your-api-token")
.build()?;
let methods = client.payment_methods("BRAND_ID", "MYR", None).await?;
println!("{:?}", methods.available_payment_methods);
let purchase = Purchase {
brand_id: Some("BRAND_ID".into()),
client: Some(ClientDetails {
email: "buyer@example.com".into(),
..Default::default()
}),
purchase: Some(PurchaseDetails {
products: vec![Product {
name: "Test Product".into(),
price: 100.0,
quantity: Some(1.0),
..Default::default()
}],
..Default::default()
}),
success_redirect: Some("https://yoursite.com/success".into()),
failure_redirect: Some("https://yoursite.com/failure".into()),
..Default::default()
};
let created = client.create_purchase(&purchase).await?;
println!("Checkout URL: {:?}", created.checkout_url);
Ok(())
}

Webhook Signature Verification
Verify incoming webhook signatures using RSA PKCS1v15 SHA-256:
use chip_sdk::verify_signature;
let is_valid = verify_signature(
request_body.as_bytes(),
&signature_header, &public_key_pem, )?;
Client Configuration
use std::time::Duration;
let client = ChipClient::builder()
.base_url("https://gate.chip-in.asia/api/v1")
.bearer_token("your-token")
.timeout(Duration::from_secs(30)) .build()?;
Payment Method Options
use chip_sdk::PaymentMethodsOptions;
let opts = PaymentMethodsOptions {
country: Some("MY".into()),
recurring: Some(true),
skip_capture: Some(true),
preauthorization: Some(false),
};
let methods = client.payment_methods("BRAND_ID", "MYR", Some(opts)).await?;
Error Handling
use chip_sdk::ChipError;
match client.get_purchase("invalid-id").await {
Ok(purchase) => println!("Found: {:?}", purchase.id),
Err(ChipError::Api { status, message }) => {
eprintln!("API error {}: {}", status, message);
}
Err(e) => eprintln!("Other error: {}", e),
