# What Is the difference between sipgate.io and the sipgate API?

With the sipgate API, you can make calls anytime to initiate calls, retrieve balances, and more. In contrast, sipgate.io uses a **PUSH-API** approach, where requests are sent from the sipgate.io servers whenever an event occurs (e.g., a new phone call).

While the sipgate API is free, sipgate.io is available as an optional feature within your sipgate team account, with packages starting at £0.00 for sipgate.io S and going up to £29.95 for sipgate.io L.

Account Administrators can activate sipgate.io through the **Plans & Packages** section in their online team account settings. The sipgate API and sipgate.io are complementary and can be used together.
