Web Services - GUI - Structure
Overview
The Web Services page allows you to use the on-screen options to build a Query URL. The query URL can be used for a variety of purposes and more detail can be found in the Web Services User Guide. This article concentrates on using this page to retrieve structures.
As selections are made from the options, you will notice that the URL will change. The URL can also be manipulated manually by adding other path parameters as detailed in the Web Services User Guide however some useful examples are shown later in this article.

Query URL
This displays the URL based on the selections that you have made. You can also add parameters, an example of which is shown in the table below.
You can copy this URL (for example if you wanted to obtain structures from another registry) and use it as you wish (for example to load the structures into your Registry using the Load via URL option).
You can also select Open URK, which will display the result in a new browser tab or downloads the resulting file (for example to load the structures into your Registry using the Load via File option).
