Enable Two-Way Sync of Contacts Between HubSpot and JustCall
Feature Overview
JustCall provides seamless two-way contact synchronization with HubSpot, automatically reflecting contact additions and updates across both platforms.
What This Feature Does
- JustCall to HubSpot: Updates made to JustCall contacts sync automatically to your HubSpot account
- HubSpot to JustCall: Changes in HubSpot contacts are reflected back in JustCall
Why Use This Feature
- Maintains a centralized, up-to-date contact database across platforms
- Reduces manual data entry and update efforts
- Enables real-time team access to current contact information
- Ensures consistent customer data across systems
- Automates processes to minimize errors
Access & Requirements
This feature requires:
- Team plan or higher subscription level
- JustCall Web Portal for configuration (not available on mobile/desktop apps)
How to Enable Two-Way Sync
- From your Dashboard, select Integrations in the left menu
- Navigate to My Active Integrations tab
- Search for and locate your HubSpot integration
- Click the Configure button
- Find the option: "Contacts added and updated in JustCall should reflect in HubSpot (2-way sync)"
- Toggle this setting on
- Click Save Changes
- Optionally apply settings across all team members via checkbox
Testing the Sync
- Add or modify a contact in JustCall and verify the change appears in HubSpot
- Update a HubSpot contact and confirm it syncs back to JustCall
Important Considerations
Sync Timing (varies by contact volume):
- Initial sync: approximately 1 hour
- Recent syncs: 30 minutes to 1 hour
- Two-way sync: 30 minutes to 1 hour
Key Limitations:
- Email addresses are not updated during sync to preserve HubSpot's contact identification method
- Phone numbers, first names, and last names sync normally
- Duplicate contacts: most recently created contact overwrites existing records
- Contacts imported from other CRMs won't sync to HubSpot unless manually edited
- Only the primary contact number updates when modified
