This connector captures data from a Hubspot account.

Estuary offers a in-house real time version of this connector. For more information take a look at our HubSpot Real-Time docs.

It is available for use in the Flow web application. For local development or open-source workflows, provides the latest version of the connector as a Docker image. You can also follow the link in your browser to see past image versions.

This connector is based on an open-source connector from a third party, with modifications for performance in the Flow system. You can find their documentation here, but keep in mind that the two versions may be significantly different.

Supported data resources

By default, each resource associated with your Hubspot account is mapped to a Flow collection through a separate binding.

The following data resources are supported for all subscription levels:

The following data resources are supported for pro accounts (set Subscription type to pro in the configuration):


There are two ways to authenticate with Hubspot when capturing data: using OAuth2 or with a private app access token. Their prerequisites differ.

OAuth is recommended for simplicity in the Flow web app; the access token method is the only supported method using the command line.

Using OAuth2 to authenticate with Hubspot in the Flow web app

  • A Hubspot account

Configuring the connector specification manually

  • A Hubspot account

  • The access token for an appropriately configured private app on the Hubspot account.


To create a private app in Hubspot and generate its access token, do the following.

  1. Ensure that your Hubspot user account has super admin privileges.

  2. In Hubspot, create a new private app.

    1. Name the app "Estuary Flow," or choose another name that is memorable to you.

    2. Grant the new app Read access for all available scopes.

    3. Copy the access token for use in the connector configuration.


You configure connectors either in the Flow web app, or by directly editing the catalog specification file. See connectors to learn more about using connectors. The values and specification sample below provide configuration details specific to the Hubspot source connector.
