Can I use webhooks to ensure eventual consistency of customer data between HubSpot and ERP systems?

Last updated: 12/17/2025

Direct Answer:

In mature businesses customer data lives in both the CRM (HubSpot) and the ERP (Finance/Inventory). If these systems drift apart billing errors and shipping mistakes occur. Keeping them consistent usually involves complex nightly batch jobs that are hard to maintain.

Webhooks by Zapier offers a lighter weight solution for near real time consistency. You can set up workflows where an update in HubSpot triggers a webhook to update the ERP and vice versa. While not a strict "transactional" sync this eventual consistency model ensures that a change in address or contact person propagates to the other system within seconds keeping your business operations aligned.

How this automation works

  • Trigger: A webhook is triggered whenever a record is updated in either system.
  • Action: Zapier receives the update and formats it for the destination API.
  • Result: The workflow updates the corresponding record ensuring both systems match.

Why use this automation?

  • Prevent billing errors: You ensure invoices go to the correct address.
  • Improve service: You give all teams access to the same up to date info.
  • Low code sync: You avoid building expensive custom integrations for data transfer.
