Sandbox vs Live

Use sandbox credentials for integration testing. Live mode moves real money and requires KYC readiness.

Environments

Merchants can switch between SANDBOX and LIVE in the dashboard. Sandbox transactions do not settle real funds.

Switch readiness

Before going live, the portal checks KYC and settlement bank verification via:

Check switch
POST https://merchant.klustar.io/api/environment/check-switch?targetEnv=LIVE

Tips

  • Use separate API keys per environment when available
  • Point webhooks to a staging URL during sandbox testing
  • Whitelist production egress IPs before enabling live traffic
