NOTE
No specific response time can be guaranteed for the use of the REST API interface
since the HTTP requests are based on a standard TCP mechanism. The response time
also depends on the system environment and system load. When using the web UI at
the same time, the response time increases.
8.2.1.4
Available variables and methods
The SIG mainly supports the GET and POST methods. For selected variables, the
DELETE function is also supported.
All API calls are executed synchronously. This means that every request is followed by a
response. A minimum response time cannot be defined for the REST API commands, as
this is also dependent in particular on the system environment and load used.
The following gives an overview of the available variables and methods. Detailed infor‐
mation and examples can be downloaded in the Open API documentation via the SICK
website, see
REST API resources
