CentraSite User's Guide : CentraSite and API Gateway Integration : Alias Mapping Details
Alias Mapping Details
This section describes how the aliases and their property values defined and published from CentraSite are mapped into API Gateway.
An alias is published from CentraSite to API Gateway when a Virtual Service associated with the alias is published from CentraSite to API Gateway.
Publishing of aliases from CentraSite to API Gateway is performed by invoking the API Gateway Deployer Service. The Deployer Service creates an alias in API Gateway for each aliasDetails element in the API's VSD.
