`"ConvertAllCustomDataToStrings": false` :

Ensures that the underlying data type is returned in the response.

e.g. Boolean: `"Custom_005": false` instead of `"Custom_005": "1"`
e.g. Number: `"Custom_006": 12` instead of `"Custom_006": "12"`

**ATTENTION**:
The respective data types are different for each entity
If the underlying data type changes, the respective data type in the response also changes automatically.
