Starting November 30, 2022, all HubSpot customers will no longer have access to API Keys and in-turn will no longer be able to use API Keys as an authentication method with HubSpot APIs.
Starting July 15th, 2022, HubSpot will no longer allow new API keys to be created. Existing API keys will work until November 30th, but accounts that do not have an API key, as of July 15th, 2022, will not have access to create a new API key. API calls made with API keys on or after Nov 30th, 2022 will return 401 errors.
It means that our existing and potential customers could not use the Hubspot integration feature by creating the new API keys since July 15th, 2022.
Our Piotnet Team will switch API Key integration method to the OAuth 2.0 Method the next time.

Any news will be updated.
All the best
