vonpay-checkout

Python SDK for the Von Payments Checkout API. Create hosted checkout sessions, verify webhook signatures, and validate signed return redirects.

Install

pip install vonpay-checkout

Requires: Python 3.9+, httpx 0.27+

Quick start

from vonpay.checkout import VonPayCheckout, VonPayError

client = VonPayCheckout("vp_sk_test_...")

session = client.sessions.create(
    amount=1499,
    currency="USD",
    country="US",
    success_url="https://example.com/order/123/confirm",
)

print(session.checkout_url)
# https://checkout.vonpay.com/checkout?session=vp_cs_test_...

Discrete-lifecycle API

The payment_intents, refunds, tokens, and capabilities namespaces give server-side control over payment intents, alongside the existing hosted-checkout sessions flow.

# Create a payment intent (auth + capture)
intent = client.payment_intents.create(
    amount=1499,
    currency="usd",
    capture_method="automatic",
    metadata={"order_id": "ord_42"},
    idempotency_key="ord_42-charge-1",
)
print(intent.id, intent.status)  # "vpi_live_…", "succeeded"

# Auth-only + later capture (fulfillment-on-ship)
auth = client.payment_intents.create(amount=1499, currency="usd", capture_method="manual")
client.payment_intents.capture(auth.id, amount_to_capture=1499)

# Refund a captured intent (partial or full)
refund = client.refunds.create(payment_intent=intent.id, amount=500)

# Create a reusable token for save-card / MIT flows
token = client.tokens.create(buyer_id="buyer_42", setup_for_future_use="off_session")

# Read the merchant's processor capability matrix before invoking optional ops
caps = client.capabilities.get()
if caps.supported_operations.partial_refund:
    # partial refunds supported — safe to offer partial-refund UI
    ...

Features

Typed session / webhook / error objects — full CheckoutSession, SessionStatus, WebhookEvent, VonPayError types.
Webhook verification — webhooks.construct_event(raw_body, signature_header, signing_secret) parses the x-vonpay-signature: t=<unix>,v1=<hex> header, verifies HMAC-SHA256 over f"{t}.{raw_body}" keyed by your per-endpoint signing secret (whsec_…), and enforces the freshness window (≤5 min old / ≤30 sec future). Accepts multiple v1= entries for zero-downtime secret rotation.
Signed return URL verification (v1 + v2) — verify_return_signature() supports both legacy v1 signatures and v2 signatures that bind successUrl, keyMode, and iat freshness.
Auto-retry — exponential backoff on 429 / 5xx with Retry-After header support.
Request ID tracing — every response includes X-Request-Id for support tickets.
