Use the HubSpot integration to trigger AI-powered outbound calls directly from your HubSpot Contact workflows. When a contact meets your enrollment criteria, hyzl places the call automatically. The criteria can be a new lead, a status change, or a deal moving stages. When the call ends, the results are written back to the contact record in HubSpot.
The hyzl AI Calling HubSpot app is coming soon to the HubSpot Marketplace. You will need a hyzl account and a HubSpot account to use this integration. Contact info@atllas.com for early access.

​
How it works

  1. Install the hyzl AI Calling app in HubSpot
  2. Connect your hyzl account from the hyzl integrations page
  3. Add the Make AI Call action to any HubSpot Contact workflow
hyzl then places the call automatically each time a contact enrolls. When the call ends, hyzl writes the status, summary, sentiment, and recording back to the contact record.

​
Setup

​
Step 1: Install the hyzl AI Calling app in HubSpot

  1. Go to the hyzl AI Calling listing in the HubSpot Marketplace
  2. Click Install app
  3. Choose the HubSpot account you want to connect
  4. Complete the authorization

​
Step 2: Connect your hyzl account

After installing the app, you need to link it to your hyzl account. This creates the campaign that the workflow action will use.
  1. Go to app.atllasx.com
  2. Open Integrations in the sidebar (under General)
  3. Find the HubSpot card and click View integration
  4. Click Connect HubSpot
  5. Follow the prompts to authorize the connection
The + Custom integration menu in the page header runs the same flow, under HubSpot. Once connected, a new inbound campaign appears on your integrations page. This is the campaign your workflow action will use.

​
Step 3: Configure the campaign

Every call triggered by the integration uses the campaign created in Step 2. Set it up before you turn the workflow on:
  1. Click Phonecall Settings on the HubSpot campaign
  2. Set the script, voice, voicemail message, follow-ups, and any other call behavior
  3. Save

​
Step 4: Add the workflow action in HubSpot

  1. Go to Automation → Workflows in HubSpot
  2. Create a new Contact-based workflow, or open an existing one
  3. Add an action
  4. Search for Make AI Call
  5. Choose your hyzl Campaign from the dropdown
  6. Save the workflow
  7. Turn the workflow on
If the campaign dropdown is empty, make sure you completed Step 2 first. The dropdown is populated from the campaigns you have connected on the hyzl side.

​
What gets written back to HubSpot

When a call completes, hyzl automatically updates the contact record. It writes these properties under the hyzl AI Calling property group:
You will still see atllas in two places in HubSpot, and both are expected. The underlying property keys are atllas_call_status, atllas_call_id and so on. These are permanent identifiers. Your existing contact data sits against them, so renaming them would orphan it. If you connected HubSpot before the rename, the group and property labels also still read Atllas. That is because HubSpot only applies a label when it first creates the property. The data written to them is unchanged either way, and you can rename the labels in HubSpot if you prefer.
hyzl creates these properties automatically when you install the app. Use them like any other HubSpot contact property. You can filter contacts, build lists, trigger follow-up workflows, or report on call outcomes.

​
Fields sent to hyzl

When the workflow action executes, HubSpot sends the following contact properties to hyzl to personalize the call:

​
Customize the phone call

The campaign linked to your HubSpot webhook controls all call behavior. That includes voice, script, voicemail message, follow-ups, call forwarding, and more. To change call behavior:
  1. Go to Integrations in the hyzl sidebar (under General)
  2. Find your HubSpot campaign
  3. Click Phonecall Settings
  4. Edit any setting
  5. Save
Changes apply to all future calls.

​
View results in hyzl

Every call triggered by the integration also appears in the campaign’s results table in hyzl. The result includes the transcript, recording, AI summary, lead warmth classification, and extracted action items. See Call Results & Transcripts for details.

​
Tips

  • Test the integration with a non-production phone number before you turn the workflow on at scale
  • Configure your campaign script before you enroll real contacts
  • The Make AI Call workflow action fires asynchronously. hyzl may place the call a few minutes after the workflow step executes, depending on queue volume
  • Monitor your hyzl calling credits before you turn on high-volume workflows

​
Disconnect HubSpot

To disconnect the HubSpot integration:
  1. Go to Integrations in the hyzl sidebar (under General)
  2. Delete your HubSpot campaign
Or from within HubSpot:
  1. Go to your hyzl app Settings tab
  2. Click Disconnect
Disconnecting stops new calls. hyzl keeps the existing call results on your contact records.
