The HubSpot data model is defined using a collection of standard JSON documents that contain the data, identifiers, and object relationships for a given service. These documents are stored on URL endpoints that are accessible using sets of proprietary REST API calls. To expose HubSpot resources to SQL applications, the driver maps HubSpot endpoints to a set of relational parent and child tables. The following sections describe the relational tables exposed by the driver along with their corresponding HubSpot REST API call.
