SQL integration to HubSpot

[LUP]

Hi,

Are there any ways to connect SQL with HubSpot
Right now we have all our live data in SQL, such as Customer/contact/product information.

And I want these data to auto sync to HubSpot.

So whenever we have a new contact in the SQL database, this contact information will automatially get updated in HubSpot. And the same with Cusomers..

Can anyone tell me which API I should use? Or is it just possible to do this through for example Zapier?

Help please

Hi  @LUP 

In 2025 the landscape for SQL - HubSpot sync is much clearer than it was a few years ago. The official HubSpot APIs you’d look at today are the CRM Objects API for core records (contacts, companies, deals, etc.) and the Associations API to maintain relationships between them

(https://developers.hubspot.com/docs/api-reference/crm-objects-v3/guide )

If you only push one way, batch imports through the Imports API are also still supported.

But if your goal is true two-way sync new contacts in SQL reflected in HubSpot instantly, and HubSpot updates mirrored back doing this by hand with webhooks and custom code will quickly turn into an API-limit headache and a maintenance trap.

In 2025, teams that want this working at scale usually skip Zapier-style patching and go for purpose-built sync platforms. That’s because manual solutions struggle with rate limiting, incremental updates, and record associations.

Stacksync was built to solve exactly this. It’s the first real-time, two-way sync engine between HubSpot and SQL (or any database). You update a record in SQL, it appears in HubSpot within milliseconds; update it in HubSpot, and it’s mirrored back. No more silent failures, no more losing weekends to API plumbing. Developers get to keep using SQL queries while Stacksync handles rate limits, webhooks, retries, and even field-level change detection automatically.

If you’re serious about keeping HubSpot and SQL aligned in 2025, skip the patchwork solutions. Start syncing in under 20 minutes at https://stacksync.com and run your CRM + database like a single system.

@johnelmer is there any way in your tool to replicate/migrate the data into our own SQL server?

Will be glad if you have any suggestions because I want to configure sync operation between Hubspot and SQL server to manage and update the data in one way.

Datawarehouse.io offers an app to connect HubSpot to an existing SQL Server database. The app, Database Sync for HubSpot, allows the user to set up a one way HubSpot >> SQL Server sync that automatically refreshes on a scheduled basis.  (Note: On premise SQL Server databases are not supported.)

Hi! Is it possible with the solution you mention to get activities and engagements associations? Like calls, meetings, conversations, emails, etc?

[johnelmer]

@CSantil the MS SQL Server for HubSpot app syncs data one way (from HubSpot to a SQL Server database in Azure). The SQL database is included with the app subscription.

If you want to sync data one way from HubSpot to your own SQL Server database (cloud hosted), there is another app called Database Sync for HubSpot that you can use. Both of these apps are available through the HubSpot App Marketplace.

However, if you want to sync data the other direction (from your own SQL database TO HubSpot), we recommend using the Census or Hightouch apps. Both are in the HubSpot App Marketplace and both have free service tiers.

Finally, if you want to sync data both directions (between HubSpot and SQL) a service like Skyvia would be more appropriate.

DM me if you have any questions about the above.

@Kavya Please PM me to discuss this option.  John

There is a relatively new app in the HubSpot App Marketplace that may meet your needs on the export side. MS SQL Server for HubSpot is a one way sync service from HubSpot to a SQL data warehouse hosted in Azure. The Azure data warehouse is included with the service, which is a major advantage over the ETL providers.

Hi, I know this is an old thread but I'm curious to know if by using MS SQL Server for HubSpot I would be able to modify my data with SQL queries and then update those same registries on HubSpot. I need to perform some UPDATE queries on my data but I haven't been able to do so in the app. 

Thanks in advance.

I would recommend to use Skyvia for this purpose. It allows to configure a two-way HubSpot and SQL sync easily within a web interface.

I would defintaley recommend  Zapier intergrations

HubSpot + MSSQL intergration  Link :  https://zapier.com/apps/hubspot-crm/integrations/sql-server

. its secure , integrates major apps like ( Salesorce , Facebook , gmail and MailChimp ) . the intergration its pretty simple doesnt required interaction with XML or code just GUI and done .

@Lup We've worked with a number of teams on HubSpot who sync their SQL database in via Hull. Common use cases we've seen are to capture product usage data or sync up a data warehouse.

One key challenge with this is calculating the difference on new data and avoiding sending any "silent" updates into HubSpot to prevent burning through API credits. This is hard to do with webhooks or Zapier for a significant volume of data.

We manage this with our SQL Importer which queries for new updates on schedule, and sync only updates with new data to external services.

Here's a little more how it works:

Hi @rainsfordt

We are a software Company, so we definitely got the power to write an application with c# or VB. I just needed to know before we looked into this.

Should we maybe catch up on e-mail, you are welcome to sent me an e-mail: lup@mindworking.dk with your contact information. in that way we can maybe help each other

We have also bought the Service Hub, so we will also do integration the ticket and conversation part.

Thanks.

Hi Lup,

Note, I am not a HubSpot employee, just someone writing their own integration with HubSpot so thought I would try and help out as I have asked a few questions in this forum.

Zapier would probably be your best bet if you don't have experience with any other programming languages such as VB or C# etc.

If you are able to program, then it might be worth using the hubspot API to write an application to keep these in sync which is what I am currently doing.

I hope this helps somewhat.
