Entity Name Search to extract PermID via DSS REST API

I am using the following request to extract orgid via name search using DSS REST API. 
What is the identifier type do I need to use to retrieve "Entity PermID" instead of "OrgId".

"OfficialNameOnly": false,
"DomicileCodes": null,
"CountryOfIncorporationCodes": null,
"TrBusinessClassificationCodes": null,
"VerifiedOnly": false,
"RegulatedOnly": false,

"IdentifierType": "OrgId",
}
}
