In Flutterwave Dashboard, open Settings, API Keys, then copy the Secret Key for test or live mode. Use a key with access to customers and transactions.
Map customer name, email, phone, transaction amount, currency, status, payment type, and created date so campaigns can target payment behavior.
Check whether the key is live or test, whether the endpoint is reachable, and whether the returned JSON path matches the List Path in Yournotify.
