Detailed information about HubSpot’s CRM objects is stored in properties, which can then be organized into groups. In addition to each object’s default properties, you can store specialized data by creating custom properties. The CRM properties endpoints allow you to manage these custom properties as well as view default property details for any object.
CRM objects are defined by a primary type and a set of properties. Each type has a unique set of standard properties, represented by a map of name-value pairs.
