• Merchant ID — Provided by Gateline when your merchant account is set up.
• Secret key
• Webhook URL — Set this as the notification (webhook) URL in your Gateline account. The signature is verified with your secret key.

Amounts are sent in minor units (×100). Gateline’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.
