Bidirectional CRM Sync: HubSpot ↔ Administrate
An event-driven integration that keeps HubSpot companies, contacts, deals and line items aligned with Administrate through a shared, observable n8n sync platform.
The challenge
Administrate needed to keep CRM data aligned with HubSpot without manual exports, duplicate records or disconnected sales and delivery teams. The integration needed to support multiple object types, incremental updates and reliable recovery when an API request failed.
The solution
We extended the proven Administrate integration platform with HubSpot as a source adapter, using the same shared orchestration, canonical transformation and run-finalization pattern as the Salesforce integration.
- HubSpot → Administrate: companies, contacts, deals and line items are pulled from HubSpot's CRM API, normalized into a canonical model and sent to Administrate.
- Administrate → HubSpot: contact profiles are batch-upserted into HubSpot, matched by email and enriched with the Administrate external ID.
- The orchestrator dispatches incremental jobs, paginates HubSpot API responses, splits results into configurable batches and preserves a watermark per object type.
- Shared data tables hold integration routing, mappings, queue state, sync state, run history and errors.
- Failures are retried and surfaced through the central error notifier, with Slack and Telegram notifications.
Results
- A reusable bidirectional CRM adapter that adds HubSpot without duplicating the integration platform.
- Companies, contacts, deals and line items can be synchronized in controlled 200-record batches.
- Incremental watermarks and batch upserts reduce unnecessary API work and prevent duplicate contacts.
Business Problems
- HubSpot and Administrate held overlapping CRM data without a reliable automated sync
- Manual exports and imports created duplicate records and stale sales data
- Multiple CRM object types required a scalable integration instead of one-off workflows

- Bidirectional, incremental synchronization between HubSpot and Administrate
- Shared orchestration and canonical mapping make the HubSpot adapter maintainable
