Furlpay Rust SDK

Official Furlpay server-side SDK for Rust — stablecoin payments, wallets, and webhook signature verification.

Zero dependencies. HMAC-SHA256 is implemented in pure Rust, so webhook verification needs no OpenSSL. The HTTP transport is intentionally left to the integrator — bring reqwest, ureq, or anything else.

Install

cargo add furlpay

Verify webhooks

Signatures use the same t=<unix>,v1=<hmac-sha256-hex> scheme as the Node, Python, and Go SDKs, with a 5-minute replay tolerance.

use furlpay::{construct_event, WebhookError};

fn handle(body: &str, signature_header: Option<&str>, secret: &str) -> Result<(), WebhookError> {
    let event = construct_event(body, signature_header, secret)?;
    // signature is valid — safe to act on `event`
    Ok(())
}

Sign payloads (useful for testing your own endpoint):

let header = furlpay::sign_payload(r#"{"type":"payment.settled"}"#, "whsec_...", None);
