On March 15, 2021, the Contact API endpoints will no longer return the profile-token value. This value was part of the public contact record functionality that was sunset in early 2019. Note that the related redirect (https://app.hubspot.com/contacts/{portalId}/lists/public/contact/{publictoken}) endpoint will stop working on March 15 as well.

Most integrations won’t be using this profile-token response value, but developers should confirm that their integration doesn’t.
