HTTP - script API

StackState Self-hosted v5.0.x

This page describes StackState version 5.0.

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.
