Consumer Application Mapping Details

CentraSite User's Guide : CentraSite and API Gateway Integration : 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API Gateway, in turn, performs the following operations when a Virtual Service is unpublished: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.

Application

The following table summarizes the mapping of an Application in CentraSite to an Application in API Gateway:

CentraSite	API Gateway	Notes
Application	Application
Key	Application ID	When an application with an UUID, say, XXX, is published from CentraSite, any existing application with the same UUID XXX in API Gateway is overwritten.
Name	Name
Description	Description
Type	Type
Version	Version
Not applicable	API access key
Not applicable	Client ID
Not applicable	Client secret
Not applicable	Client name
Not applicable	Scopes Name Description
Not applicable	Token lifetime
Not applicable	Token refresh limit
Not applicable	Redirect URIs

Application Identifiers

The following table summarizes the mapping of an Application's Identification in CentraSite to an Application's Identifiers in API Gateway:

CentraSite	API Gateway	Notes
Identification token	Other identifiers Token	Beginning with version 10.1, API Gateway offers the option Token by which incoming messages from a particular application can be recognized at run-time.
From IP-V4 Address	IP address range
To IP-V4 Address	IP address range
From IP-V6 Address	IP address range
To IP-V6 Address	IP address range
Partner Id	Partner identifier	Beginning with version 10.1, API Gateway offers the parameter Partner identifier to specify the third-party partner's identity.
Consumer Certificate	Client certificates
Not applicable	Claims
Not applicable	Other identifiers Hostname Token Username WS-Security username XPath

Note:

When an application with an UUID, say, XXX, is published from CentraSite, any existing application with the same UUID XXX in API Gateway is overwritten.

API Key

The following table summarizes the mapping of an Application's API key:

CentraSite	API Gateway	Notes
API Key	Application
Key	Application ID
Name	Name	When an application with an UUID, say, XXX, is published from CentraSite, any existing application with the same UUID XXX in API Gateway is overwritten.
Not applicable	Description
Not applicable	Created
API Key String	API access key
Not applicable	Client ID
Not applicable	Client secret

Note:

The identifiers of an API key in CentraSite are not mapped to API Gateway.

Note:

When an application with an UUID, say, XXX, is published from CentraSite, any existing application with the same UUID XXX in API Gateway is overwritten.

OAuth2 Token

The following table summarizes the mapping of an Application's OAuth2 token:

CentraSite	API Gateway	Notes
OAuth2 Token Client	Application
Key	Application ID
OAuth2 Client Name	Name	When an application with an UUID, say, XXX, is published from CentraSite, any existing application with the same UUID XXX in API Gateway is overwritten.
Not applicable	Created
Not applicable	API access key
OAuth2 Client Id	Client ID
OAuth2 Client Secret	Client secret

Note:

The identifiers of an API key in CentraSite are not mapped to API Gateway.

Note:

When an application with an UUID, say, XXX, is published from CentraSite, any existing application with the same UUID XXX in API Gateway is overwritten.
