HTTP - script API

Functions to execute HTTP requests.

This page describes StackState version 4.3.

The StackState 4.3 version range is End of Life (EOL) and no longer supported. We encourage customers still running the 4.3 version range to upgrade to a more recent release.

Go to the documentation for the latest StackState release.

Sometimes it may be useful to process the retrieved topology or telemetry data using an external tool. For example, to perform analysis using a custom Python script, a cloud service or an Machine Learning framework. StackState can call out to any external service via HTTP using the functions in this script API.

The permission execute-restricted-scripts is required to execute scripts using the HTTP script API in the StackState UI analytics environment. For details, see the analytics page permissions.
