Payzum for pretix

Accept crypto and stablecoin payments (USDC, USDT and more, multi-chain) for your events. Payzum is non-custodial: funds settle directly to your own wallet.

• Buyers are redirected to a hosted checkout page where they pick the asset and network; the ticket price stays denominated in your event currency. No card fields, no extra PCI surface.
• Orders are marked as paid from the signed payment notification (HMAC-SHA-512, verified by the official payzum Python SDK), never from the buyer's browser return.
• Redelivered notifications are idempotent, and a late expired event can never downgrade an order that already settled.

Installation

On a pip-based pretix installation (pretix ≥ 2025.2, Python ≥ 3.11):

pip install pretix-payzum

Then restart pretix, enable Payzum under Settings → Plugins for your event, and configure it under Settings → Payment → Payzum:

No webhook needs to be configured in the Payzum dashboard: every invoice the plugin creates carries its own callback URL pointing back at your pretix instance. The instance must be publicly reachable — Payzum delivers notifications server-to-server.

Statuses

The gateway emits five payment statuses; only finished marks the order paid:
