If you need to get monitor configuration details with names as in Export Monitors option in GUI, as a workaround, you can call the following API and get it. The response will not be in standard format, as it was actually constructed for generating CSV output.
Configuration APIs such as /monitors, /threshold_profiles will return IDs whereas reporting APIs such as /reports/summary/ will return names.
Generally, the expectation is configuration APIs will mostly be used in automation scripting, where IDs will be more useful and enough.
Reporting API calls would be made to generate a report in the user desired custom format, where they will expect only names. So those APIs will return names.
In your case, you want to generate a custom report for the configuration details. We will think about the use case and provide documented support for such an API in future.
