# v1 Overview

> Maintain existing v1 integrations while planning the move to Pagou v2.

Use the v1 archive only to keep an existing integration stable. New work should start on v2.

## What remains in v1

* auth validation via health check
* account balance lookup
* legacy Pix payment routes
* legacy webhook configuration

## Operating rule

Keep v1 changes minimal and operational. Route all net-new product work to v2.
