Invoking an endpoint from a map

A service, or endpoint definition can be referenced in a map card either directly, or by creating an action that uses the REST adapter.

Whether using an action, or defining the card directly, ensure the following conditions are present:

Connection Type - Selet the REST adapter.
Operation - Select Use service definition.
Service - Select the service from the list.
Endpoint - Select the endpoint from the list.
Authentication - To use the authenticaiton scheme defined in the service, specify "Use Endpoint Definition". Alternatively, you can override the scheme defined in the service and select an alternate scheme.
Properties - Specify the values for service and endpoint parameters as properties in the form: param-name-1=value1 param-name-2=value2
