Return Type: Collection Of CustomPropertyValue
Declaring Type: EntityObject
Domain API Request: GET

Parameters

• customPropertyCode
  The code of the custom property
  Type: string

• search
  The search text - searches by value or description. Can contain wildcard character %.
  Type: string
  Optional: True
  Default Value: null

• exactMatch
  If true the search text should be equal to the property value
  Type: boolean
