Sandbox
Build against the real thing, safely.
Every account comes with a sandbox: test keys, test cards, test bank accounts, and the same webhook events production fires. Switch to live keys when you are ready — nothing else changes.
What you can test
The whole lifecycle, not just the happy path.
Every payment channel
Card, bank transfer and USSD flows behave as they do in production.
Failure cases
Trigger declines and timeouts so you can prove your retry logic works.
Payouts and bulk runs
Validate account resolution and batch handling with test accounts.
Real webhook events
Sandbox fires the same signed events, so your listener is genuinely tested.
Virtual accounts
Create test NUBANs and simulate credits into them.
Zero risk
No real money moves, and sandbox data is fully separated from live.
