True or false? Authentication is required to use HubSpot’s API.

In the HubSpot Data Integration certification, the statement is True because authentication is a fundamental security requirement for any external system to access or interact with your HubSpot data. HubSpot’s API endpoints are not public or "open" to anonymous traffic; every request must be verified through an authentication method—such as Private App access tokens or OAuth—to confirm the identity of the requester and ensure they have the appropriate permissions (scopes) to read or write data. Without this verification step, sensitive customer information stored in the CRM would be vulnerable, making authentication the essential "handshake" that establishes a secure, authorized connection between HubSpot and any third-party application.
