Question from Reddit user:
Hello,
We’re using mongodb with all our contacts info, and we want to create/update records on HS.
basically – we want to integrate mongodb to hubspot.
to be sure, before I’ve asked the question here:
i did read this post: https://community.hubspot.com/t5/APIs-Integrations/Can-we-integrate-mongo-db-to-hubspot-export-data-ā¦.
but no clear guidelines on how to do it
we’re looking for native integration, so we don’t want to use Zapier or similar platforms.
HS support couldn’t help, they referred me to here.
anyone can help?
Answer from Nabil:
The short answer is:
Since you are specifically looking to avoid middleware like Zapier for a native-style integration between your MongoDB contact data and HubSpot, the optimal and most scalable approach is a direct, custom API integration.
This involves creating a script or application that uses the MongoDB REST APIs (like the Atlas Data API, if you’re using Atlas) to read your contact data and then uses the HubSpot API to create or update those records in HubSpot’s CRM.
This method gives you complete control over data mapping and transformation, ensuring the flexible document structure of MongoDB correctly translates into HubSpot’s contact properties and objects.
The long answer is:
Your desire for a non-middleware solution is perfectly valid, especially when dealing with the high volume or complex, unstructured nature of MongoDB data, where you need precise control over data transformation and synchronization logic that platforms like Zapier can complicate or make expensive.
The combination of HubSpot API, MongoDB REST APIs, Google Tag Manager, and a custom hosting solution like Stape or Google Cloud Platform is an excellent and cost-effective solution because it creates a robust, server-side data pipeline.
Your synchronization script, likely built in Python or Node.js, would run on a budget-friendly serverless environment on Google Cloud Platform or a similar service.
This script would be triggered by a schedule or a webhook from your MongoDB environment.
When it runs, it first uses the MongoDB REST APIs to query for new or updated contact documents.
Crucially, before sending this data to HubSpot, the script transforms the flexible MongoDB document structure into the specific JSON format required by the HubSpot API’s contacts endpoint (e.g., POST /crm/v3/objects/contacts).
It handles the logic for creating new contacts or updating existing ones, typically using email as the unique identifier for matching records, which is a key CRM best practice to avoid duplicates.
The mention of Google Tag Manager and a server-side tagging solution like Stape or Google Cloud Platform enhances this solution by providing a powerful, parallel path for event-based data synchronization.
For example, when a contact in HubSpot performs an action that updates a property, HubSpot can fire a webhook to your server-side environment.
This server then processes the data and uses the MongoDB REST APIs to update the corresponding contact document in your database.
This approach effectively enables a reliable, two-way sync for a fraction of the cost of many enterprise-level integration tools, giving you the “native” control you seek while keeping your infrastructure lean and efficient.
