Under GDPR, companies need a lawful reason to use and process contact data and must keep records of consent and evidence other lawful purposes of processing.
The contact property Legal basis for processing contact's data allows you to collect, track, and store lawful basis of processing via contract, legitimate interest, and/or consent for your HubSpot contacts.
When accessing contact data via the Contacts API, this property uses the name
hs_legal_basis. Any contact that has that property set would be accessible through the API as with any other contact property, and the property can also be set or updated for contact records through the API.
However, the options for the property cannot be modified through the API using the Contact Properties API. The property options can only be updated from inside HubSpot, but it is possible to pull any custom options that may have been set for the property through the Contact Properties API. For this reason, it is recommended that your integration use the Contact Properties API to get the options for this property, since individual HubSpot accounts may not use the default settings.
