Many operations on SystemLink Web Application can be controlled from external applications by using HTTP API. Here, you can see how to get a tag value by use of HTTP API on Swagger UI.

Firstly, you need to log in to the SystemLink Web Application and open Tag Viewer on Data Visualization. Then, please create a tag. In this example, we create a tag named test.

Double-click the created tag, enter an arbitrary number in the "Value" field, and save it. Select the HTTP API from the question mark in the upper right corner of the tag viewer.

On the Swagger UI page for SystemLink Tag Service,  go to the section for GET/v2/tags/{path}/values/current command.

You can test this HTTP API by clicking "Try it Out". To get the value of the tag named "test" created in this example earlier, set as follows and execute.

If the HTTP API is executed normally, Code 200 with Response body and Response headers will be returned as described above.
