Enter the **apiKey** from Optimal Alerts.

Choose to automatically **refund** and/or **blacklist** when an alert is received. The automatic refund is a full refund. The automatic blacklist will blacklist email, phone, IP address, and billing address. It will also cancel all active subscriptions for the customer.

Alerts are received and a proper attempt is made to match the alert to a successful transaction. The evaluation is not perfect. Matching is done with card bin, card last 4 digits, arn (if provided from the gateway at the time of the transaction), date, and amount.

Refunds are automatically sent back to Optimal Alerts with the refund status.
