HubSpot Connector
Connector implementation
Build the HubSpot integration
CRM platform for marketing, sales, and customer service with contact and deal management
Implementation Overview
Implement a HubSpot connector that authenticates to the vendor surface, normalizes source records in Tajo, and activates eligible data in Brevo.
Treat this as an implementation guide. Build and validate the auth, mapping, sync, and operations paths before production use.

Authentication
-
Use github.com/HubSpot/HubSpot-Public-API-Spec-Collection to generate or validate typed API clients and request models.
-
Validate the MCP server endpoint at mcp.hubspot.com and document required headers, auth grants, and tool availability.
-
Keep developers.hubspot.com/mcp linked from the connector runbook so operators can confirm vendor behavior during incidents.
-
Store credentials per Tajo workspace and keep tenant-specific secrets out of connector configuration files.
-
Add a credential smoke test that verifies read access to a harmless resource before running backfills or enabling webhooks.
Data To Sync
Start with these inferred data domains, then confirm exact vendor resources and permissions from the source documentation:
- Contact and identity records
The connector should make source records idempotent by keeping a stable key such as a vendor object ID, email address, event ID, ticket ID, order ID, or campaign ID. If the vendor only exposes list APIs, Tajo should store the cursor strategy and replay policy explicitly.
Sync Shape
| Resource | Direction | Conflict handling |
|---|---|---|
contacts | inbound | n/a |
deals | inbound | n/a |
Mapping To Tajo/Brevo
HubSpot has a typed contract, and every resource on it is read for context rather than projected into Brevo. That is a recorded decision, not a gap: no field of this connector currently becomes a Brevo contact, list, or event.
The conventions that apply to every connector — stable external IDs, normalization, backfill and sync strategy, error handling, and the builder checklist — are documented once under “Applies to every connector” on the connector catalog.
