API Gateway server acts as an API front-end that receives API requests which enforces throttling.
Configure Gateway using API Key Controlled Authentication
It also enforces security policies, allows requests to the back-end service and then passes the response back to the requestor
Boomi API Management supports both internal and external authentication types. Internal authentication uses the atom-controlled authentication that is present in the Boomi Platform. The API users are managed by the Platform.
