Setting up Adyen in PremiumPress

Activate the free plugin, then open your theme’s payment settings and add your Adyen credentials:

• API key — Adyen Customer Area → Developers → API credentials → your web-service user → API key.
• Merchant account — The exact merchant account code (case-sensitive).
• Live URL prefix — Live only — Customer Area → Developers → API URLs → prefix. Leave blank in Test.
• HMAC key — Recommended — the HMAC key from your standard webhook. Add a webhook in Customer Area

One-time payments confirm on return and via the notification webhook. Recurring plans are not billed automatically through Pay by Link — use a one-time plan with Adyen. The plugin requires PremiumPress 12.
