Connect Website Forms to HubSpot Automatically
Every lead your website captures through a Site2CRM form or AI chat agent becomes a HubSpot contact within seconds, with the company record created and linked for you. No middleware, no Zaps, no copy-paste.
How the Connection Works
Site2CRM connects to HubSpot with OAuth 2.0. You approve the connection once inside HubSpot and never handle an API key. The connection requests read and write access to contacts, companies, and deals, and nothing else. HubSpot access tokens expire every 30 minutes; Site2CRM refreshes yours automatically about five minutes before expiry, and re-authorizes on the spot if HubSpot ever rejects a call, so the sync does not quietly stop working after half an hour like a naive integration does.
Open Integrations
In Site2CRM, go to Integrations and choose HubSpot.
Connect
Click Connect. You are sent to HubSpot to log in.
Grant access
Approve the requested contact, company, and deal permissions. You need sufficient rights in your HubSpot account to install apps.
Done
The integration shows Connected, HubSpot becomes your active CRM, and every new lead syncs from that moment on.
What Syncs to HubSpot
Contacts
Each captured lead becomes a HubSpot contact with email, first name, last name, and phone.
Companies
When a lead includes a company name, Site2CRM finds the matching HubSpot company by name, or creates it if it does not exist yet.
Associations
The contact is linked to its company inside HubSpot, so records land connected instead of orphaned.
Field Mapping
| Site2CRM field | HubSpot field |
|---|---|
| Name | firstname, lastname |
| Phone | phone |
| Company | company record (name), linked to the contact |
Phone syncs whenever the visitor provides it. Lead score, source, and conversation history stay in Site2CRM, where your team works leads before they ever reach reporting.
How duplicates are prevented
Deduplication happens at capture, before anything touches HubSpot. When the same email submits again within 24 hours, Site2CRM matches it to the existing lead instead of creating a new one, so repeat form fills and re-opened chat sessions do not turn into duplicate HubSpot contacts. Companies are matched by exact name and reused rather than recreated.
Reliability
Sync runs as a background job within seconds of capture, so your visitor never waits on HubSpot's API. Tokens refresh automatically before they expire. If a sync to HubSpot fails, everyone in your organization gets an email alert. And every lead is always stored in Site2CRM first, so even if HubSpot is unreachable, the lead itself is never lost.
Requirements
- Works with every HubSpot plan, including the free HubSpot CRM
- Permission to install apps in your HubSpot account
- A Site2CRM Starter plan or higher (the free plan does not include CRM sync)
Two-way visibility
HubSpot is the one CRM Site2CRM also reads back from. With HubSpot connected, your existing HubSpot contacts appear alongside newly captured leads in the Site2CRM lead list, so reps working the capture queue see the full picture without switching tabs.
Frequently Asked Questions
Does it work with the free HubSpot CRM?
Yes. Contact and company creation work on every HubSpot tier, including HubSpot Free CRM. You do not need a paid HubSpot subscription to sync leads.
Will repeat submissions create duplicate contacts?
No. Site2CRM deduplicates at capture: a repeat submission from the same email within 24 hours updates the existing lead instead of creating a new one, so it never becomes a second HubSpot contact.
What happens when the HubSpot token expires?
Nothing you will notice. HubSpot access tokens expire every 30 minutes, and Site2CRM refreshes them automatically about five minutes early, with an immediate re-authorization retry if HubSpot rejects a call.
Which Site2CRM plans include the HubSpot integration?
Starter includes up to two CRM integrations, and Pro includes unlimited integrations. The free plan captures and stores leads in Site2CRM but does not sync to external CRMs.
Do AI chat leads sync the same way as form leads?
Yes. When your AI chat agent captures a visitor's contact details, that lead goes through the exact same sync pipeline as a form submission and appears in HubSpot within seconds.
