# Launch Readiness

> A production evaluation checklist for teams moving from sandbox to live Zentra traffic.

Launch readiness is the point where the integration, operators, and compliance posture all agree on the same evidence trail.

Use this page before live traffic. Use [Going Live](/guides/going-live) for the longer production handoff guide.

## Required Before Live Traffic

<Steps>
  <Step title="Prove the first reviewed flow">
    Run at least one sandbox transfer or payment flow end to end with idempotency, API state inspection, and webhook handling.
  </Step>

  <Step title="Verify event consumers">
    Confirm signature verification, duplicate event handling, retry behavior, and alerting for failed webhook deliveries.
  </Step>

  <Step title="Confirm tenant controls">
    Check enabled products, limits, key environment, webhook endpoints, and internal access rules for the tenant.
  </Step>

  <Step title="Prepare operational review">
    Make sure support, finance, and compliance teams know where to inspect request state, delivery history, and audit evidence.
  </Step>

  <Step title="Switch keys deliberately">
    Move from sandbox keys to live keys only after the reviewed flow and operational checks pass.
  </Step>
</Steps>

## Production Acceptance Criteria

* Live API keys are stored outside client-side code and source control.
* All money-affecting writes use deterministic request identity where documented.
* Webhook consumers verify signatures and deduplicate events.
* Draft/reference namespaces are not used in default production flows.
* Operational owners know how to investigate a failed provider callback, retry, or reconciliation mismatch.
* The integration team has a rollback or pause path for launch issues.
