# Origin Domains

> Restrict which website origins may initialize payment flows.

## Overview

Add allowed origins (e.g., [https://www.example.com](https://www.example.com)) to prevent unauthorized usage from other domains.

## Best practices

* Add production and sandbox origins separately
* Use exact origins (scheme + host + optional port)
