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.
