Supported Alias and Policy Combinations

API Gateway provides a set of aliases whose runtime-specific environment variables can be used in configuring the policy routing endpoints, routing rules, endpoint connection properties, and outbound authentication tokens. The types of aliases whose properties you can use for the policy configurations are:

Not all policies support the full set of aliases that are available in API Gateway. Some aliases are applicable only with certain policies and for certain policy parameters. For example, a Simple alias applies to the routing and traffic monitoring policies, whereas an Endpoint alias applies only to the routing policies. When you define a Straight Through Routing policy with a simple alias, the alias property is defined using the Endpoint URI field. When you define the same Straight Through Routing policy with an endpoint alias, the alias property is defined using a set of fields - Endpoint URI, SOAP Optimization Method, HTTP Connection Timeout, Read Timeout, Pass WS-Security Headers, and Keystore Alias.
