# Go-live Checklist

> Use this production checklist before you switch a Pagou integration from sandbox to live traffic.

Use this checklist before sending live traffic to Pagou.

## Required checks

* Production credentials are stored in your secret manager.
* Your backend uses the production base URL and production token only through configuration.
* `external_ref` is persisted for every create operation.
* Webhook ingestion returns `200 OK` quickly and deduplicates by event ID.
* Reconciliation exists for both payments and transfers.
* Logs capture `requestId`, your integration reference, and the Pagou resource ID.

## Strongly recommended checks

* Sandbox happy paths have been run for Pix, voucher, and card, if they are in scope.
* Refund and cancel workflows have an operator-facing playbook.
* Alerting exists for webhook failures, retry storms, and reconciliation backlog.
* Finance and support teams know where to find `requestId` and resource IDs.
* Frontend fulfillment waits for webhook or reconciliation, not only the initial create response.
