Hi @ShubhangiPawar,

Which authentication method are you using? [https://developers.hubspot.com/docs/api/crm/crm-custom-objects](https://developers.hubspot.com/docs/api/crm/crm-custom-objects) (see the “Authentication methods” section here)

Assuming that it’s a private app, you can learn more about setting scopes here: [Legacy private apps - HubSpot docs](https://developers.hubspot.com/docs/api/private-apps)

Hey @ShubhangiPawar

If the message error is about scope

you need to adjust better the Objects that you are going to be able to read/edit from the API.

Follow the articles Karsten shared.

Hope this helps
