Billing
Billing happens in your dashboard, not through the API. Choose a monthly or yearly plan, toggle renewal, or schedule a cancellation there — access continues to term end, and the dashboard always shows where you stand.Paying
Start checkout from the dashboard billing section and complete payment with an enabled gateway for your currency (NGN or USD, detected from your location). Invoices, payment history and the gateways available to you live in the same place.Pay as you go
Instead of a subscription, buy email credit packs from the dashboard. Your included monthly allowance is spent first; purchased credits roll over. The dashboard shows the balance and every movement.Provider callbacks
POST /payments/webhooks/{provider} (for example paystack) is called by the payment provider, never by integrators. Point the provider dashboard at that URL; deliveries are signature-verified and processed idempotently, so retries are safe.
