There's a new version of the HubSpot API
As of November 30, 2022, HubSpot API Keys are being deprecated and are no longer supported. Continued use of HubSpot API Keys is a security risk to your account and data. Your API Keys could be deactivated at any time after Nov. 30th, and we recommend that you migrate to Private Apps as soon as possible so you do not lose business-critical functionality.
The HubSpot public endpoints are powered by the same underlying technology as the core HubSpot application. As a result, HubSpot engineering closely monitors usage of the public APIs to ensure a quality experience for users.
Below, you'll find the limits by which a single integration (as identified by an access token) can consume the HubSpot public APIs. If you have any questions, please post them in the developer forum.
