# API Group name

* An API group is a text the user creates for grouping one or more APIs together. 
* The group name becomes a part of the base URL. All APIs that are in the same group share the same base URL. 
* Creating a meaningful API Group Name is recommended so it can be referenced easily. The API Group Name can be selected or created in the Details tab.
