Contact API in HubSpot allows different software applications or systems to communicate and share information about contacts (people) in a HubSpot account.

It provides a way for developers to access and manipulate contact data. This integration enables you to manage and use contact information across various platforms seamlessly.

Getting started with Contact API

Before we move to create and set up a contact API, let's understand a few terms associated with Contact API.

  • Batch Endpoints: The batch endpoints allow you to make a GET or POST call that further returns or creates/updates multiple contacts at once, respectively.

  • Deduplication: The prime identifier for any contact in HubSpot is the email address, and the Contacts API de-duplicates email addresses in HubSpot automatically.

  • Contact Properties: The details for a contact record are stored in contact properties. Further, HubSpot users can also store required custom data by creating custom contact properties.

  • Contact Owners: The owner of a contact record is managed via the contact owner property, with the internal name of hubspot_owner_id. While using this property via the Contacts API, the internal ID of the owner is required. 

  • Lifecycle Stage Updates: Suppose you are trying to convert a contact into a customer (to reflect an updated deal stage) via the API. In that case, you have to set the value of the lifecycle stage property to “customer.”

  • Associations between Contacts and other Objects: A contact can be associated with deals, engagements, organizations, and tickets. To create and manage object associations, you can use HubSpot CRM Associations API.

  • Response Details: Data returned by the Contacts will be read-only, except for the individual contact property values.

  • Source-type: The source type of a property version reveals how the property was modified, and it is different from the original source for a contact record. For instance:
    • If the source type is API, the contact property is updated using the Contacts API.
    • Similarly, if the source type is FORM, the value has been updated based on form submission.

  • URL: We need a URL for requests and responses.

  • Data: Push JSON object to update or create the contacts.

Frequently Asked Questions

How do I create a contact API in HubSpot?

To create a contact API in HubSpot, you'll need to make a POST request to a specific address, which is "/crm/v3/objects/contacts." In this request, you should include the contact information you want to add within a properties object. Additionally, if you wish to link your new contact with other existing records like companies or activities, you can use the associations object. This allows you to create and manage contacts within your HubSpot account, making it easier to organize and engage with your customer data.

How do I use HubSpot for contacts?

Using HubSpot for managing contacts is simple. Start by going to "Contacts" in your HubSpot account. Then, click "Create contact" in the upper right corner. A panel on the right will open, allowing you to enter contact details. Once you input their name and email, you can add more information as needed. This helps you keep track of people you interact with, making it easier to nurture leads, manage customer relationships, and grow your business efficiently.

How many API calls do you get with HubSpot?

In HubSpot, the number of API calls you receive depends on your subscription tier. If you have the API add-on at any tier, you get API access. However, when integrating with OAuth, there's a limit of 100 requests allowed every 10 seconds. This restriction ensures that HubSpot's servers are not overwhelmed, maintaining system performance and reliability during data exchanges with external applications or services. It's essential to be mindful of these limits when building integrations or utilizing the API to avoid any disruptions in your data flow.

How many contacts can you have in HubSpot?

In HubSpot, you can have up to fifteen million non-marketing contacts for free when using their marketing tools and CRM. However, if you require more than fifteen million contacts, you should get in touch with HubSpot for further assistance. This means you can manage a substantial number of contacts with HubSpot's free tools, but there's a limit, and any exceeding contact management needs special consideration.
