CentraSite User's Guide : CentraSite and API Gateway Integration : Consumer Application Mapping Details
Consumer Application Mapping Details
This section describes how the consumer applications and their property values defined and published from CentraSite are mapped into API Gateway.
A consumer application is published from CentraSite to API Gateway in the following scenarios:
*When publishing Virtual Services, CentraSite sends a list of registered consumer applications along with the VSD of the service to API Gateway.
API Gateway, in turn, performs the following operations when a Virtual Service associated with the consuming applications is published:
*Creates a SOAP or REST API for the Virtual SOAP Service or Virtual REST Service.
*Create an applications for the consuming application.
*Registers an application to the API.
*When republishing Virtual Services, CentraSite sends the updated list of registered consumer applications along with the VSD of the service to API Gateway.
API Gateway, in turn, performs the following actions when a Virtual Service associated with the consuming applications is published:
*Updates the details of an existing application with the recent changes.
*Creates an application for the newly defined consuming application.
*Unregisters an application that has been recently removed from the API.
*When unpublishing Virtual Services, CentraSite also unpublishes the list of consumer applications that were registered to the service.
API Gateway, in turn, performs the following operations when a Virtual Service is unpublished:
*When synchronizing consumer applications, API Gateway performs the following actions:
*Create a new consumer application and registers to the required API.
*Updates the details of an existing consumer application and the application's registration status for an API.
*Any consumer application provided by CentraSite but not associated to the Virtual Service is removed.
*Requesting API keys and OAuth2 tokens
Publishing of consumer applications from CentraSite to API Gateway is performed by invoking the API Gateway Deployer Service. The Deployer Service creates an application in API Gateway for each consumer application, API key, and OAuth2 token specified in the API publish request.
