Overview

Target Audience

The alpha version of TAQTIQA's REST-API service is intended for early adopters and developers before the beta-REST-API version is released. Specifically, the alpha-REST-API may evolve rapidly. This allows us to test the functions of TAQTIQA's streaming trade and quote data service, and confirm that the REST-API functions properly with client applications. Once a alpha-REST-API change or feature is considered complete it will made available via TAQTIQA's beta-REST-API service.

Changes to alpha-REST-API and services are in response to accepted feature requests, user feedback and reproducible issue reports

Hypertext Constraint (HATEOAS)

There are several explanations of the ideas/behavior that the hypertext constraint, or Hypermedia As The Engine Of Application State (HATEOAS) encapsulates. One useful description is:

Finally, each representation that the client receives from the server represents the state of the user's interaction within the application. For instance, when the user submits the form to recieve another page, the user changes the state of the application from her point of view. When a user, just browsing a website, the user (sic) changes the state of the application with each click on a link to load another page.

In this example, to change the state of the application, the user relies on forms and links found in the HTML. HTML is a hypermedia format, allowing link and form controls to let you flow through the application and thereby change the state of the application.

This way of using hypermedia of the representation (such as HTML) to denote and manage the state of the application is called hypermedia as the engine of application state, or in short form the hypertext constraint.
