Hey, @JPade👋 Can you provide more details, please? The errors in your screenshot indicate there are missing required properties in your request. Can you use Postman and successfully create or update this quote? Without seeing the request body you are sending, it's very difficult for our community members to troubleshoot with you.
I don't have all the details using an integration platform. I am more curious what would cause the hs_slug field not to popluate automatically, is there a setting on the hubspot account? If we create a unique combo and send it the quote updates successfully.
