Setting up Unzer in PremiumPress

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

• Private key — Unzer Insights → Company data → API Keys. The private key authenticates every server call.
• Public key — Optional — used by client-side Paypage components; kept for reference.

The buyer pays on the hosted Unzer Paypage and returns here; the payment is then confirmed via the Unzer API before the order completes. Amounts are sent as a decimal in the order currency. The plugin requires PremiumPress 12.
