What HubSpot is

HubSpot is a CRM and marketing platform with APIs for contacts, deals, companies, and marketing events.

Evonx helps you build applications that use HubSpot APIs — this page does not claim an official partnership unless one is explicitly stated.

What you can build

  • Bidirectional contact and company sync
  • Deal stage webhooks into your product
  • Marketing event and form submission handlers
  • Internal tools that enrich HubSpot records from app usage

Application types

SaaS products

RevOps internal tools

Customer portals

Technical considerations

  • Use private apps or OAuth with least-privilege scopes
  • Respect HubSpot API rate limits and batch where possible
  • Idempotently map external IDs to avoid duplicate contacts

FAQ

Can Evonx-built apps sync deals without replacing HubSpot CRM?

Yes. Your app remains the product system of record for usage while HubSpot stays the CRM—sync keys and webhooks keep both sides aligned.

Which auth model should we use for HubSpot?

Private apps work for single-tenant internal tools; OAuth is better when each customer connects their own HubSpot portal.

How do we avoid duplicate contacts on sync?

Store HubSpot record IDs on your entities and upsert by email or external ID so retries do not create clones.
