Setting up Releax in PremiumPress

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

• API base URL — The API base URL from your Releax integration pack (change if your account uses a different host).
• Merchant ID — Provided by Releax when your merchant account is set up.
• Secret key
• Webhook URL — Set this as the notification (webhook) URL in your Releax account. The signature is verified with your secret key.

Amounts are sent as decimals (major units). Releax’s merchant API is partner-gated — confirm endpoint paths and the signature recipe against your integration pack before going live. The plugin requires PremiumPress 12.
