Connect one Hubspot to 2 SFDC instances

[rjonesSolaria]

Can you use Datasync to integrate a second instance of Salesforce to one Hubspot account? How would you do this?

Or is there any other possible way to do this? 

I would interested to know if you can integrate separate business units to separate Salesforce accounts...

Hi @rjonesSolaria,

There might be hacky ways to do this but generally the answer would be no: https://knowledge.hubspot.com/salesforce/install-the-hubspot-salesforce-integration

"You can connect only one Salesforce instance per HubSpot account."

(On a side note, I can't even start to imagine the complexity that connecting more than 1 account would entail, as it would require three-way mappings.)

Best regards

Short answer,
you can’t connect two Salesforce orgs to a single HubSpot portal with the native integration in 2025. HubSpot explicitly supports only one SFDC instance per account as documented here (https://knowledge.hubspot.com/salesforce/install-the-hubspot-salesforce-integration).

Business Units won’t change that, they segment branding and assets, not integrations (https://knowledge.hubspot.com/account/set-up-business-units).

If you must run one HubSpot to two SFDC orgs, the clean approach is an integration layer that routes records by a HubSpot property, for example Country or Business Unit.

Keep an eye on API limits and batch in 100s where possible. If you prefer to stay low code, you can trigger on “When a webhook is received” in HubSpot workflows and hand off to your router from there (https://knowledge.hubspot.com/workflows/set-when-a-webhook-is-received-workflow-triggers). I’m inferring you’re on Professional, correct me if not.

Hope this clarifies a lot of things. And I'm always happy to share advices if needed.

@rjonesSolaria Vertify does this and can help with multiple SFDC instances to one Hubspot portal. Different CRMs due to geography, brands, or M&As are common. Let me know if you have questions.

Hi there! Do you have a link for Vertify- I tried Googling and am unable to find more information. For context, I am a HubSpot sales rep and have a customer looking to connect multiple SFDC instances to a singular HubSpot portal

Sure thing: www.Vertify.com 
Here is a page about multi-CRM integrations. https://vertify.com/use-case-multi-crm/

@karstenkoehler thanks for the info! You always respond to my questions and I appreciate that! 

It doesn't have to be 3-way. It will be some data goes to one instance and some data goes to the other - based on applicable location. Basically US-based incoming leads and contacts and activity syncing to the US-based SFDC and the remainder of the world syncing to the other SFDC instance.
