Integrating AR System forms with a third-party application by using the REST API

The REST API is a simple stateless architecture that runs over the HTTP. The AR System server uses JavaScript Object Notation (JSON) format to transmit data between a server and a web application. The advantage of REST is having a limited number of operations for the interactions between clients and services.

The API is a web service that conforms to the architectural principles of Representational State Transfer (REST). Each API is called by issuing a standard HTTP request method: POST, GET, PUT, or DELETE (more commonly known as the CRUD operations: Create, Read, Update, and Delete).

The client creates new entries by issuing POST requests. The details of an individual entry or list of entries is retrieved using a GET request. The client issues PUT requests to modify an entry object. When an entry object is no longer needed, the client issues a DELETE request to remove the entry. 

The AR System server uses Jetty as a web server to service the REST API requests. You should use Secure Sockets Layer (SSL) certificates with the Jetty server to service the REST API requests. For more information, see Configuring the REST API by using SSL certificates.

Clients such as curl, Postman, or BMC TestHttpClient tool can make calls to REST APIs. For information about the BMC TestHTTPClient tool, see the knowledge article on BMC Communities  TestHttpClient - Command line tool to test HTTP(S) services .
