WhatsApp now lets people without the app join voice and video calls from a browser link, removing a common friction point for external meetings. Hosts generate a call link, admit guests from a waiting room, and — Meta says — calls remain end-to-end encrypted, free and without time limits.
What changed
With the new guest calling feature, a host creates a call link from WhatsApp and shares it with participants. Anyone who opens that link in a computer browser can type in a name and wait in a virtual lobby until the host admits them. Once allowed in, guests can join 1:1 or group calls that support up to 32 participants.
Meta describes several guardrails around guest access: guests need the host’s approval and cannot see other participants’ phone numbers, send messages in the call, or add others directly. Hosts can remove guests at any time. Only users with a WhatsApp account can create call links.
Guests get the essential in-call features available on the web build: screen sharing, emoji reactions and a “raise hand” control to request speaking rights. Meta also says it will add calendar integrations later this year for Google Calendar and Outlook via a WhatsApp plugin, so organizers can drop a WhatsApp call link into an invite.
Why this matters for marketers, agencies and teams
This reduces the friction of inviting external participants to short, ad hoc or client-facing calls. Use cases include quick sales demos, tutoring sessions, candidate screening and lightweight customer support interactions where asking someone to install an app is a barrier.
For teams that already use WhatsApp for client communication, guest links simplify scheduling and lower the friction for external stakeholders. A calendar plugin that reliably creates single-use or expiring links would make WhatsApp another viable join option alongside Zoom and Meet.
Privacy and control are central to Meta’s positioning: guests don’t gain access to phone numbers and hosts keep admission and removal controls. Those controls are useful, but organizations in regulated industries should weigh them against compliance and auditing requirements before replacing established conference platforms.
Practical implications and recommended practices
Treat a WhatsApp guest link like any other meeting access token: avoid posting links in public forums, generate unique links per meeting where possible, and use the waiting room to vet entrants. Limit link creation to trusted staff accounts and include link hygiene in internal meeting policies.
Before using guest calling for critical workflows, test the browser experience and the specific features you need — screen sharing reliability, audio/video fidelity and moderation controls — because web implementations vary across operating systems and browsers. When you add WhatsApp links to calendar invites, confirm how the plugin creates and manages links (single-use, expiry, or reuse).
What to watch next
Two practical questions matter for professional users: how Meta implements end-to-end encryption for web guests in practice, and whether WhatsApp will offer enterprise-grade controls such as centralized logging, admin policies or audit trails for Business accounts. Track the calendar-integration rollout to see if the plugin supports enterprise identity systems or enforces meeting policies.
Short term: pilot guest calling in low-risk scenarios, lock down which accounts can create links, and document expected behaviors for external participants. If your workflows require logging, policy enforcement or strict auditability, hold off on wholesale migration until Meta publishes more details about encryption handling and administrative features.
