I have developed a PowerShell module for integration with the ServiceNow API. It provides functionality to create new objects, update objects, get-objects and remove objects from ServiceNow.
The module is named AMServiceNow – (AM is the prefix for our company Automize).
Current module version is 126.96.36.199
The module includes PowerShell help description for each function.
