8 Service APIs

This section provides a reference for APIs that should be implemented by this Building Block.

The GovStack non-functional requirements document provides additional information on how 'adaptors' may be used to translate an existing API to the patterns described here. This section also provides guidance on how candidate products are tested and how GovStack validates a product's API against the API specifications defined here.

The tests for the Information Mediator Building Block can be found in this GitHub repository.

The majority of functions provided by the Information Mediator Building Block are either defined in the “service access flow” or configured by the administrator via the web User Interface. There is, however, a “Directory Service” which can provide listings of clients, methods, and available API specifications for services on the Information Mediator. The directory is managed by admins of members. The directory service centralizes and offers knowledge of all enrolled members and their services along with the information necessary to bind a third-party application as a consumer of that service. These services are described here:

• API metadata

and changes to the API definitions can be made by submitting a pull request on this repository. Additional APIs may be implemented by the Building Block, but the listed APIs define a minimal set of functionality that should be provided by any implementation of this Building Block.

The services can be accessed via the following Service APIs:

8.1 Service Access

The full API definition of all available services is the set of all available OpenAPI descriptions.

One can take any of the available OpenAPI descriptions and call service according to that description.

This call must be forwarded to IM local Security Server and path part of the called URL must begin with the address of service in the form /r1/{instanceId}/{memberClass}/{member}/{application}/{service}/ followed by the service path with possible query parameters. The address of the service may be already listed in the OpenAPI description or must be added to the path if not provided by OpenAPI.

8.2 Directory Services

8.2.1 Member Discovery

At development time, to see which organizations are available on GovStack, an administrator of application A sends a GET request to the security server: url-of-local-information-mediator-security-server/r1/listClients

The response is an array of organizations with descriptions. API MAY implement paging of output.

List clients defined in the instance

Clients of the security server have the capability to obtain a list of potential service providers within a GovStack instance, including both members and applications. To do so, they should initiate an HTTP GET request to the security server. The specific request URL will be either http://SECURITYSERVER/listClients or https://SECURITYSERVER/listClients, depending on whether HTTPS protocol usage is enabled for interaction.

When submitting this request, the placeholder SECURITYSERVER must be replased with the actual address of the security server. One can also retrieve a list of clients from other federated GovStack instances by adding an additional HTTP parameter:

instanceId - a code of the instance.

For instance, if you wish to fetch the list of clients associated with the instance labeled as ABC, your request URL should take the form of http://SECURITYSERVER/listClients?instanceId=ABC.

  ]
}

8.2.2 Service Discovery

At development time, an administrator at application A sends a GET request to the security server: url-of-local-information-mediator-security-server/r1/INDIA/GOV/MEMBER/APPLICATION/{listMethods || allowedMethods}

The response is an array of services (either all services or services that the requester is authorized to access via “allowedMethods”). API MAY implement paging of output.
