How are you sending WhatsApp messages when a HubSpot contact property changes?

Hi everyone,

We’ve been trying to set up WhatsApp notifications that trigger automatically when a HubSpot contact property changes — things like sending a WhatsApp message when a deal stage updates or a lead status changes.

Native HubSpot workflows support email and in-app notifications, but WhatsApp requires a separate integration. We ended up building a small free app to handle this (HubSpot Notify on the Marketplace), but I’m curious how others in the community are solving this:

1. Are you using a third-party tool like Make/Zapier to bridge HubSpot webhooks to WhatsApp?

2. Are you using a WhatsApp Business API provider directly?

3. Has anyone found a clean way to do this without extra middleware?

Would love to hear what’s working for your team. If anyone wants to try the app we built (it’s free while we’re still in beta), happy to share details — just drop a reply or DM.
