Hi Eugene,  
Try retrieving a list of company properties via API (GET /crm/v3/properties/companies) and see if the custom field names (“city”, “country”, etc.) match exactly what HubSpot is expecting.

Hi @Eiregi

Everything is looking good in your JSON. Please re-verify the internal name of all properties or maybe there is a mismatch is property value so do have a look into it. Try sending a req with different properties so that you can find out which property is causing the error.

I hope this will help you out. Please mark it as **Solution Accepted and upvote** to help another Community member.
