Dive Deeper into Key Features

Explore key features and APIs for customization and extensibility, and start to build custom solutions on the HubSpot platform.

Custom Objects

HubSpot will let you create custom CRM objects that work just like the default objects, such as contacts or tickets. These custom objects can be customized for your specific business or industry needs, such as creating a custom object to manage subscriptions to your service, or to represent things like real estate or in-person events.


Timeline Events

Timeline events let you add entries to the timeline for CRM objects. They work best with things where time is a crucial data point. Events appear in the record timeline based on the timestamp of the event, so they'll appear near other activities that happened around the same time.


Calling Extensions

The Calling Extensions SDK allows apps to provide a custom calling option to HubSpot users directly from a record in the CRM. Calling extensions are set up as a feature of a public app. You must use the Calling Extensions API to create the calling settings for your app. Once this is done, your calling service will be added as an option for the call button when your app is connected to a HubSpot account.


Enhanced Associations

Account admins can now define their own association labels, which provide more context for the relationships between records. Association labels are supported between contacts, companies, deals, and tickets. For example, you can create a contact-company association label called Consultant to show that a contact is a consultant for a company, rather than an employee.


CRM Cards

Custom CRM cards allow information from other systems to appear on HubSpot contact, company, deal, or ticket records. CRM cards work primarily through webhooks. When a HubSpot user views a record in HubSpot, we'll send a webhook to your system to get the details for the card. This webhook fetch is made each time any user views a record of the supported types in any account with your app installed


Custom Properties

Use properties to store information on CRM records. HubSpot provides a set of default properties for each CRM object, and you can also create and manage your own custom properties either in HubSpot or using the properties API. When creating properties, it’s important to consider how to architect your data. In many cases, creating custom properties for HubSpot's standard objects is the right course of action.
