Hi @GGuliani
When troubleshooting authorization issues, it’s essential to confirm the scopes you’re requesting in the authorization URL.
Double-check that the CRM list read scope is spelled correctly and aligns with HubSpot’s API documentation.
Moreover, ensure that the HubSpot account you’re using has the necessary permissions to access the requested scopes.
Certain CRM features may only be available in higher-tier HubSpot plansand may not be accessible in free or basic tiers. Verifying these details will help resolve authorization issues and ensure seamless integration
Hope this helps - Happy to help further!!
Thank you very much and have a great one!
Warm regards
