# Prepare your integration for live

> Complete credential, payment, webhook, and operations controls before processing real money.

Enable live after completing the end-to-end sandbox flow. Changing the host without these controls can lose events or duplicate operations.

## Complete the checklist

* Use a separate live key with minimum scopes
* Store keys and webhook secrets in a secret manager
* Send idempotency for every compatible mutation
* Verify webhooks against the original body
* Deduplicate financial events and commands
* Handle `429`, timeouts, and retryable errors
* Retain `request_id` without logging sensitive data
* Test every card, SPEI, OXXO, and installment flow you offer
* Reconcile payments, refunds, payouts, and transfers
* Confirm the merchant is ready to accept payments

Live uses `https://api.simplepay.mx`. Reject any configuration that combines this host with sandbox keys or webhooks.

Compare errors, latency, and webhook deliveries before and after rollout. Stop on missing routes, `5xx`, or incomplete reconciliation.
