UTOPAY for MODX — miniShop2 (MODX 2.8 – 3.x) and miniShop3 (MODX 3, beta)
=========================================================================

Cards, Apple Pay, Google Pay, PayPal, Revolut (4.5%) and crypto — USDT / USDC / ETH (1.5%).
Guide: https://utopay.app/plugins/modx

After installing:
1. System → System Settings → namespace "utopay": set utopay_secret_key (UTOPAY dashboard →
   Integration → API keys; start with utopay_sk_test_…) and the currency / rate of your prices.
2. miniShop2 / miniShop3 → Settings → Payments: the package created two DISABLED methods —
   "Card, Apple Pay, Google Pay, PayPal" and "Crypto: USDT, USDC". Enable them and link to deliveries.
3. Place a test order → UTOPAY sandbox → green ✅ button → the order becomes paid.
   Then switch to the utopay_sk_live_… key.

Notifications need no setup: each payment carries its own signed callback URL; the payment is always
re-read through the UTOPAY API before the order is marked paid.
