To create a Service Endpoint click on the endpoint submenu on the entity palette and choose the service endpoint icon:
The Service Endpoint Entity is a simple generic HTTP based resource with a URL.
Gateways in LunchBadger are Express Gateway instances. A Service Endpoint in Express Gateway is any resource that the gateway proxies in front of.
Models and Functions have HTTP URls pointing to them as HTTP based microservices. When you connect a Model or Function to a Gateway, a service endpoint is declared behind the scenes in Express Gateway to point to the HTTP URL of the Model or Function.
