ChatGPT Business HubSpot connector does not support HubSpot custom objects in a usable way, anyone else hit this?

Hi all,

We’re using ChatGPT Business with the existing HubSpot connector and have run into a limitation that feels pretty significant for any HubSpot setup that relies on custom objects.

What we’re seeing:

  • the connector can access some standard CRM objects

  • but it does not provide usable access to HubSpot custom objects

  • in practice, that means we can’t use ChatGPT Business properly against our actual HubSpot data model

This is not just about one custom object. The real issue is that the connector does not appear to support custom objects generally, which makes it hard to future-proof if your HubSpot portal uses custom objects as part of normal operations.

Our use case includes custom objects such as:

  • p146395150_monthly_site_surveys

  • p146395150_sites

  • p146395150_service_actions

We separately verified through direct HubSpot API access that:

  • the custom object schemas are visible

  • the properties are visible

  • the records are readable

  • so the limitation does not appear to be HubSpot itself

Relevant read scopes in our setup include:

  • crm.objects.line_items.read

  • crm.objects.owners.read

  • crm.objects.orders.read

  • crm.objects.invoices.read

  • crm.objects.listings.read

  • crm.objects.leads.read

  • crm.objects.users.read

  • crm.objects.forecasts.read

  • crm.objects.marketing_events.read

  • crm.schemas.custom.read

  • crm.objects.custom.read

  • crm.objects.feedback_submissions.read

  • crm.objects.goals.read

  • crm.objects.companies.read

  • crm.objects.deals.read

  • crm.objects.contacts.read

What we would expect from the existing connector:

  • custom object schema discovery

  • custom object property discovery

  • querying/searching custom object records

  • support for associations involving custom objects

  • and ideally support for current and future custom objects in a connected HubSpot portal

Questions for the community:

  1. Has anyone else run into this with the existing HubSpot connector in ChatGPT Business?

  2. Have you found any supported workaround that still keeps the experience browser-based and user-friendly?

  3. Has anyone had confirmation from OpenAI about whether general support for HubSpot custom objects is planned?

I’m posting this partly to sanity-check whether others are seeing the same thing, and partly because this feels like a major gap for teams that use HubSpot custom objects seriously.

Thanks.
