In order for Alight Analytics to have access to your HubSpot account, you'll need to connect in the Connect Page of ChannelMix Control Center.
Once the connection is authorized you will need to provide the 'portal_id' for the newly created connection. The 'portal_id' value will need to be manually entered once the profile has been associated with the connection.
Need help finding the portal ID? Upon logging into HubSpot, your Hub ID/portal ID will be available on the top right of your screen. The Hub ID/portal ID is located under the email address associated with the account.
