The Visitor Identification API is now in public beta! You can read more about it and get started here. This is open to all Pro+ portals as of now, no need to be ungated.
The new Visitor Identification API enables you to provide details about visitors’ identities to the chat widget after they’ve been authenticated by an external login system. So, if a visitor logs in (by providing their email address), the Visitor Identification API can send their identity to HubSpot’s chat widget.
This API also works automatically with HubSpot’s private content membership for CMS Hub or Knowledge Base, no additional setup required!
Please let me know if you have any questions or feedback. This API is still in beta, by using this API you agree to our developer beta terms.
