Product Enablement and Configuration {#boarding-products}
=========================================================

You can enable and configure different products for merchants in the `Business Center` and the Product Enablement and Configuration Service (PECS) API.  
You can use the PECS API to enable, subscribe, and configure products for a merchant. The PECS API is used during merchant onboading and after merchant onboarding:

* **Merchant onboarding**: PECS is invoked by the Boarding Registration Service (BRS) API.
* **Post-merchant onboarding**: PECS is called to update the merchant's product subscriptions or configurations.
