# Echo the Platform

Echo the Rapyd platform.

> **Note:**
>
> The base URL for the POS production environment is **https://pos.rapyd.net**. It requires its own access key, which is different from the access key for the Payment API. See [Accounts and Credentials](https://docs.rapyd.net/en/accounts-and-credentials.md "Accounts and Credentials"). To set up a sandbox environment for the POS API, contact **[Rapyd Client Support](https://support.rapyd.net)**.
