Thanks for the tag, @Jaycee_Lewis!

@EEnzipe, to make sure I understand correctly, you've created a test HubSpot portal, and within that test portal, created a Private App, correct?  You're then receiving authentication requests while making API calls to that portal, attempting to use the credentials generated by the private app.

If so, it likely has to do with how you structure the API call and provide the authentication.  Before the introduction of Private Apps, you would use the portal's API key as the authentication in the header, like:

--header 'hapikey: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxx' \

With Private Apps, instead of providing the value as a hapikey, you set it as a Bearer token:

--header 'Authorization: Bearer xxx-xxx-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx' \

If you're using Postman to test the API calls, try switching the Authorization type from API key to Bearer Token:

Give that a try, and let us know if it helps!
