Companies 

In HubSpot, companies store information about the organizations that interact with your business. The companies endpoints allow you to manage create and manage company records, as well as sync company data between HubSpot and other systems. 

Learn more about objects, records, properties, and associations APIs in the Understanding the CRM guide. For more general information about objects and records in HubSpot, learn how to manage your CRM database.

To create new companies, make a POST request to /crm/v3/objects/companies.

In your request, include your company data in a properties object. You can also add an associations object to associate your new company with existing records (e.g., contacts, deals), or activities (e.g., meetings, notes).

Company details are stored in company properties. There are default HubSpot company properties, but you can also create custom properties.

When creating a new company, you should include at least one of the following properties in your request: name or domain. It is recommended to always include domain, because domain names are the primary unique identifier  to avoid duplicate companies in HubSpot. If a company has multiple domains, you can add them through the API by using the hs_additional_domains field with semicolons separating each domain. For example: "hs_additional_domains" : "domain.com; domain2.com; domain3.com".

To view all available properties, you can retrieve a list of your account's company properties by making a GET request to /crm/v3/properties/companies. Learn more about the the properties API.

For example, to create a new company, your request may look similar to the following:

When creating a new company, you can also associate the company with existing records or activities. In the associations object, include the following fields:

You can also include the label field to assign a defined association label that describes the association. Learn more about associating records via the associations API.

For example, to associate a new company with an existing contact and email, your request would look like the following:

You can retrieve companies individually or in batches.

• To retrieve an individual company, make a GET request to /crm/v3/objects/companies/{companyId}.
• To request a list of all companies, make a GET request to /crm/v3/objects/companies.
• To retrieve a batch of specific companies by record ID or a custom unique identifier property, make a POST request to crm/v3/objects/companies/batch/read.

For these endpoints, you can include the following query parameters in the request URL: 

For the batch read endpoint, you can also use the optional idProperty parameter to retrieve companies by a custom unique identifier property. By default, the id values in the request refer to the record ID (hs_object_id), so the idProperty parameter is not required when retrieving by record ID. To use a custom unique value property to retrieve companies, you must include the idProperty parameter.

For example, to retrieve a batch of companies, your request could look like either of the following:

You can update companies individually or in batches. For existing companies, the company's record ID is a unique value that you can use to update the company via API.

To update an individual company by its company ID, make a PATCH request to /crm/v3/objects/companies/{companyId}, and include the data you want to update.

To associate a company with other CRM records or an activity, make a PUT request to  /crm/v3/objects/companies/{companyId}/associations/{toObjectType}/{toObjectId}/{associationTypeId}. 

Learn more about associating records with the associations API.

To remove an association between a company and a record or activity, make a DELETE request to the following URL: /crm/v3/objects/companies/{companyId}/associations/{toObjectType}/{toObjectId}/{associationTypeId}.
