Short answer
For ChatGPT Business or Enterprise organisations, HubSpot's Ads access is off by default. Ask your organisation's global admin to enable it in the OpenAI Admin Console. If it is enabled and still restricted, contact the account admin and re-authorise.
Other fixes
- Sign in to the correct ChatGPT Ads account
- Confirm HubSpot permissions to connect ad accounts
- Re-run authorisation; disconnect and reconnect if needed
- Contact HubSpot support with both account details
Questions
Will disconnecting delete campaigns?
