Crate pakasir_sdk 

Unofficial Rust SDK for the Pakasir payment gateway.

The crate covers the REST surface of the API plus a few helpers most integrations end up writing anyway:

• Client – async HTTP client with retries, jittered backoff, and Retry-After handling.
• TransactionService – create / cancel / detail.
• SimulationService – sandbox payment simulation.
• WebhookParser – parse and validate webhook payloads.
• build_payment_url – build the hosted checkout redirect URL.
• QrGenerator – render QRIS strings (or anything else) to PNG bytes.

Error messages are localized through Language (English by default, Indonesian when the client is configured for it).

Quick start

use pakasir_sdk::{Client, PaymentMethod, TransactionService};
use pakasir_sdk::transaction::CreateRequest;

let client = Client::builder("your-project-slug", "your-api-key").build();
let transactions = TransactionService::new(client);

let response = transactions
    .create(
        PaymentMethod::Qris,
        &CreateRequest {
            order_id: "INV123456".into(),
            amount: 99_000,
        },
    )
    .await?;

println!("payment number: {}", response.payment.payment_number);
println!("total payment:  {}", response.payment.total_payment);

Modules

Module	What it does
client	HTTP transport, retry policy, builder.
constants	SDK metadata, API paths, payment / status enums.
error	The crate-wide Error enum and Result alias.
i18n	Language selector and message catalog.
payment_url	Hosted checkout redirect URL builder.
qr	QR PNG generation.
simulation	Sandbox payment simulation.
timefmt	Small RFC 3339 parsing helper.
transaction	Transaction service.
webhook	Webhook parser and event validation.

The gRPC server layer from the original implementation is not part of this crate.
