HubSpot integration for your inbox

Connect a HubSpot portal and every DM, WhatsApp, and SMS conversation in Zernio's inbox lands on the right HubSpot contact, with new contacts created for people HubSpot has never seen.

How It Works

Three steps to a synced CRM

1

Profile

default

HubSpot

Connect the portal

Request a link with GET /v1/connect/hubspot and send the portal admin to it to approve the app.

2

PATCH /v1/accounts/{id}/hubspot-settings

await zernio.accounts.updateHubSpotSettings({
  path: { accountId: 'acc_8f2a' },
  body: {
    syncContacts: true,
    logMessages: true,
  },
});

Choose what syncs

Contact sync and message logging start on. Turn either off with one PATCH to the account's settings.

Conversations reach HubSpot

Each inbox message is matched to a contact by email or phone and logged on its timeline.

Each Zernio profile connects to one HubSpot portal through OAuth, with contact read and write access only

Features

Everything you need to ship HubSpot features

Every message on the timeline

Inbound and outbound messages are logged on the contact, with links to their attachments.

Two switches

Turn contact sync or message logging on or off per portal. Settings survive a reconnect.

Contacts matched or created

Zernio finds the HubSpot contact by email, then by phone, and creates one when there is no match. It never overwrites what your team typed.

Native WhatsApp and SMS

WhatsApp and SMS messages land as HubSpot communications on their own channel. Other channels land as notes.

Minimal access

The app asks only for contact read and write. Disconnecting uninstalls it from the portal.

Same API key

Connect portals and change settings for your users through the API, from the same key you post with.

Integrate

Three ways in. Same API behind all of them

Write it yourself with the SDKs, hand it to an agent over MCP, or run it from a shell.
