HubSpot API Integration
Manage contacts, deals and marketing workflows through HubSpot's CRM platform.
What HubSpot API integration does
HubSpot is where marketing and sales operations meet, and the integrations that pay off are the ones that push product behaviour into it. A contact record with lifecycle stage, usage signals and deal context lets marketing segment on what customers actually do rather than on what they filled into a form.
Our HubSpot integration syncs contacts, companies, deals and custom properties in both directions, with deduplication against a stable external ID so one customer does not become three records. Workflow triggers can fire from product events, which is what makes lifecycle automation reflect reality — a trial that goes quiet, a plan upgrade, a usage threshold crossed — instead of firing off a schedule that has no relationship to the customer's behaviour.
What teams build with it
Product-led lifecycle stages
Drive lifecycle stage from real product usage rather than from form submissions.
Contact and company sync
Keep records consistent in both directions with deduplication and clean merge behaviour.
Deal automation
Create and advance deals from product events such as trial start or plan upgrade.
Behaviour-triggered marketing
Fire HubSpot workflows from product signals so campaigns respond to what customers actually do.

HubSpot API integration — FAQs
Can product events trigger HubSpot workflows?
Yes — that is usually the point of the integration, and it is what makes lifecycle automation reflect behaviour rather than a schedule.
How is duplication avoided?
Records are matched on a stable external ID rather than on email alone, which is the usual source of duplicates when customers change addresses.
Can we sync custom properties?
Yes. Custom properties are mapped explicitly and versioned alongside standard ones.
