Credit Memos API Access, 403 Error After Enabling All Scopes

I’m integrating with the HubSpot CRM API using a private app and I’m trying to create records in the Credit Memos object via the following endpoint:

POST https://api.hubapi.com/crm/v3/objects/credit_memos

Credit Memos is visible and functional in our HubSpot portal UI and I have a private app with all relevant scopes enabled.

I initially received a MISSING_SCOPES error. After enabling all relevant scopes, now receiving a 403 Forbidden response. And I have tested via Postman with the same access token but get the same result.

Is crm/v3/objects/credit_memos publicly available via the API for private apps? If so, what specific scopes are required?

If not, is there a timeline for when this will be available, or an alternative endpoint to achieve the same result? And do you have a workaround for this if direct access to the endpoint isn’t available?

Hi @Rs01,
Thank you for posting to the Community!
I’d like to tag in our Top Contributors to see if they have experienced this before -- Hi @KlemenHrovat @deepikaverma and @HubSpot_Corey do any of you have any ideas on this one?
Thank you in advance!
