verified_user1. Official Merchant Provisioning Journey

Because FuturePayNG processes regulated financial transactions in Nigerian Naira (NGN), live API keys are not self-generated in the browser. Production keys are bound to verified merchant accounts and issued via encrypted out-of-band channels after KYC verification.

To maintain bank-grade security, live webhook secrets and merchant API keys must be periodically rotated or immediately invalidated if compromised.

Zero-Downtime Dual-Secret Window

When a rotation is initiated via Invoicecheckout@futurepayng.com, FuturePayNG enables a 24-hour transition window where incoming webhooks can be verified against either the primary or secondary secret.

Emergency Key Invalidation

In case of key exposure, send an urgent subject line [URGENT: REVOKE KEY] with your Merchant ID to Invoicecheckout@futurepayng.com. Operations invalidates compromised keys within 15 minutes.
