Alerting

For more details, please refer to the Alerting feature.

Alerting

To use the Alerting API, it's necessary to generate an access token.

Access Token

A comprehensive toolkit, with practical usage examples, is accessible on GitHub.

This toolkit comes pre-installed as a default component within the on-premises platform, located at /datasentinel/soft/datasentinel_toolkit.
