Sample error from my python script response body.

@GAlinio - have you included a valid API token in the header of the request you issued? The token would be the mechanism that associates the API call with the specific HubSpot instance (portal ID).

Hi Steve, thank you so much for taking the time to respond to my question. Adding the token to my header solved the issue! I appreciate your guidance on this, as it helped me better understand how API calls connect to HubSpot instances. Thanks again for your support!💪
