Email Changes
How Email Changes works in Paycux, what it is for, and the smallest setup that gets it running.
Introduction
Email Changes is part of the Paycux platform. This page explains what it does, when to reach for it, and the smallest working setup you can ship.
Everything below applies to both environments. Build and test in staging, then promote the same configuration to production without changing your code — only the API key and client ID differ.
Native email changes
Native email changes is handled by Email Changes rather than by your application code. Paycux exposes it through the same API surface as the rest of the platform, so the client you already configured needs no additional setup.
Configuration lives in the dashboard and is versioned per environment. Change it in staging, confirm the behaviour, then apply the same change to production.

Directory ownership
Directory Sync keeps your user list in step with the customer's directory. Paycux receives create, update and delete operations and normalizes them into a single shape regardless of the source system.
Deletes arrive as deactivations. Treat a deactivated user as a user who can no longer sign in, and decide separately whether to delete their data.

How do email changes interact with identity linking?
A user record holds the identity Paycux resolved for the person: email, name, verification state, and the identities they have linked. It is the object your application should key on.
Users are unique by email within a project. When the same person arrives through a second provider, Paycux links the identity to the existing user rather than creating a duplicate.
