# Tune the desk’s detectors

The desk runs detectors over your own data — see which ones run for your organization, park one you no longer want offers from, bring it back, or retire it for good.

Work · a play in 2 steps.

## The steps

1. See the detectors and where each stands for your organization. — [suggestionSchemas](/reference/suggestion-schema/suggestionSchemas/)
2. Park a detector — existing offers stay until they expire or close — bring it back, or retire it permanently. — [transitionSuggestionSchema](/reference/suggestion-schema/transitionSuggestionSchema/)

## The calls

Every operation this use case runs, in the order it first appears, with the request and the response its reference page shows.
