You have more important things to worry about and your developer's time costs too much to waste with something as small as writing a request to the HubSpot API. Instead of bothering a developer or struggling to learn some cURL, Python, or JavaScript yourself, just use this interface to make use of HubSpot's most game-changing feature, custom objects.

• Create new custom objects for your HubSpot portal(s)
• Edit your custom objects
• Associate your custom object with HubSpot's standard objects and other custom objects
• See all of your custom object definitions in one place
• Set mandatory/required properties for quality assurance on your custom object records
• Define the properties you can use to search for you custom object records
• Pick the key properties you'll see when your custom object records are referenced in the HubSpot UI
• Be sure that you stick to custom object best practices
• Avoid mistakes when creating and editing your custom object definitions
• Fully orchestrate your custom objects to maximize their value
