HubSpot ERP integration for marketing and sales teams

HubSpot is often where marketing and early-stage sales live. The ERP knows what customers actually bought and paid. Connecting them lets marketing segment by real purchase behaviour and lets sales see order history.

Overview

What this integration is for

We integrate HubSpot's CRM APIs with the ERP, keeping each system authoritative for the data it does best.

02Use cases

Common use cases

01

Purchase-based segmentation

Campaigns targeted by what customers buy.

02

Deal to order

Won deals flow into operations.

03

Account context

Sales sees orders and balances in HubSpot.

03 — Architecture

API architecture

HubSpot webhooks notify changes to contacts and deals; the integration fetches full records via the CRM v3 APIs. ERP changes are pushed in batches using batch endpoints.

Custom properties or custom objects hold ERP data so HubSpot reporting and workflows can use it.

04Reliability

Authentication, errors and retries

01

Authentication

A HubSpot private app access token or OAuth app with only the required scopes, stored securely.

02

Error handling

Property validation and association errors captured with record IDs and routed to an exception queue.

03

Retry strategy

Retries respect HubSpot rate limits with backoff; deduplication via unique identifiers.
