# Post Installation Setup

1. Request license key from this link <https://www.greytrix.com/gumu/request-product-license/>
2. By default, the Sage 100 Web API is created on port **80** under the **Default Website** as well as a separate site. If you prefer to run the Web API on a dedicated port, keep the separate site. Otherwise, you can convert the folder created under the **Default Website** into an application and delete the duplicate site.

**Note:** The **Sage 100 Web API** application must run under the **Sage 100 Web API Application Pool**, which should be configured to use a **Windows domain user** account with **administrative rights**.
