API Gateway

Aruba Central supports a robust set of RESTRepresentational State Transfer. REST is a simple and stateless architecture that the web services use for providing interoperability between computer systems on the Internet. In a RESTful web service, requests made to the URI of a resource will elicit a response that may be in XML, HTML, JSON or some other defined format. APIsApplication Programming Interface. Refers to a set of functions, procedures, protocols, and tools that enable users to build application software. to enable users to build custom applications and integrate the APIs with their applications. The Aruba Central API framework uses OAuthOpen Standard for Authorization. OAuth is a token-based authorization standard that allows websites or third-party applications to access user information, without exposing the user credentials. protocol to authenticate and authorize third-party applications, and allows them to obtain secure and limited access to an Aruba Central service.

API Gateway and NB APIs

The API Gateway feature in Aruba Central supports the REST API for all Aruba Central services. This feature allows Aruba Central users to write custom applications, embed, or integrate the APIs with their own applications. The REST APIs support HTTPHypertext Transfer Protocol. The HTTP is an application protocol to transfer data over the web. The HTTP protocol defines how messages are formatted and transmitted, and the actions that the w servers and browsers should take in response to various commands. GETGET refers HTTP request method or an SNMP operation method. The GET HTTP request method submits data to be processed to a specified resource. The GET SNMP operation method obtains information from the Management Information Base (MIB). and POSTThe HTTP POST method is used for transferring data from a client (browser) to a server using the HTTP protocol. The POST method is considered a secure way of transferring data from a client as it carries the request parameter in the message body and does not append it in the URL string. operations by providing a specific URLUniform Resource Locator. URL is a global address used for locating web resources on the Internet. for each query. The output for these operations is returned in the JSONJavaScript Object Notation. JSON is an open-standard, language-independent, lightweight data-interchange format used to transmit data objects consisting of attribute–value pairs. JSON uses a "self-describing" text format that is easy for humans to read and write, and that can be used as a data format by any programming language. format.

For secure access to the APIs, the Aruba Central API Framework plug-in supports OAuth protocol for authentication and authorization. The access tokens provide a temporary and secure access to the APIs. The access tokens have a limited lifetime for security reasons and the applications should use the refresh API to obtain new tokens periodically (every 2 hours).

The following figure illustrates the API gateway workflow for the users:

Accessing API Gateway

To access the API Gateway:

1. In the Account Home page, under Global Settings, click API Gateway.

The API Gateway page is displayed. You can get new tokens and refresh old tokens. To obtain a new token application, you must set authentication parameters for a user session.

Important Points to Note

The admin user profile of MSP has System Apps & Tokens tab which displays all the apps and tokens generated locally in the admin user profile. This tab also displays all the apps created in the non-admin user profiles. Clicking these apps lists out all the associated tokens created for the non-admin user profile.
Administrator role is specific to an app and hence the administrator account related RBAC library APIs and decorators must contain the application name as one of the parameters in the access verification query.
The decorators associated with Account Home, Network Operations, or ClearPass Device Insight must contain account_setting, central, or optik as app names respectively, as one of the parameters.
