Connect HubSpot with Anything in your Stack
Unify data in your CRM to build your single source of truth
HubSpot is where your prospect, customer, sales, and support data lives. But today’s companies rely on far more than just one platform. Whether you’re working with an ERP, data warehouse, internal tools, or any point solution, our team helps you connect everything to HubSpot—so you can take full advantage of the world’s best CRM.

What is a Custom HubSpot Integration?
The HubSpot App Marketplace offers hundreds of connected apps, but many of these integrations are shallow, rigid, or simply not designed for how modern businesses operate. Legacy systems, internal tools, and unique workflows often require something more. That’s where custom HubSpot integrations come in.
HubSpot has best-in-class APIs, flexible extensibility, and powerful developer tools. With the right technical partner, you can connect almost any system to HubSpot and build a solution that not only syncs data, but truly integrates functionality.
Aptitude 8's approach to custom integrations
Our Solutions Architects help you design the right data model, while our full-stack HubSpot developers build robust components tailored to your business. From custom coded actions to CRM extensions, we build for both flexibility and usability—ensuring non-technical teams can manage what we deliver.
Areas of Expertise
When we build custom HubSpot integrations, our goal is always the same: interoperability. We make sure your HubSpot CRM is fueled by the right data—not siloed workarounds—so your team can use every feature with confidence.
We offer five core approaches depending on your systems, resources, and goals:
01 IPaaS Configuration
Integration Platform as a Service (iPaaS) tools offer flexibility without the need for custom code. They’re ideal for teams with Ops or IT resources who want to manage integrations in-house.
We scope, build, and document your iPaaS-based HubSpot integration—then hand it off for long-term ownership.
With iPaaS, you can:

Create records
Create records in systems like ERPs, project management tools, or service platforms

Query data
Power contextual automation by querying external tools

02 Custom Coded Action Driven Integrations
With HubSpot Operations Hub Pro, we unlock deep automation using custom coded actions. These allow your team to connect HubSpot to any external system via API, without ever leaving a workflow.
Our HubSpot API integration services are built for scale and accessibility. Your operations team can continue owning workflows without relying on engineering to make changes.
Here’s how we used React to build a dynamic UI experience inside HubSpot.

The possibilities are endless with custom coded actions. You can:
03 Hosted Custom Integrations
When iPaaS solutions aren’t custom enough or become too expensive at scale—a hosted integration may be the answer.
We build and deploy fully custom integrations on Azure, AWS, or Google Cloud. You can manage them in-house, or we’ll host and support them as a managed service.
See how we helped FloQast launch a virtual event experience by building a fully hosted integration on HubSpot, driving a 35% increase in event conversion.
04 Data Warehouse Integration
Most modern companies and software teams use a data warehouse to manage product usage, billing data, and historical snapshots.
We help you either integrate data you want to leverage in your CRM with HubSpot, or extract data from HubSpot for storage in your data warehouse.






05 Integration Advisory
When you’re building an integration for your own app, it often makes more sense to keep development in-house, especially if there are private APIs or strict security requirements.
We provide architectural guidance, help you choose the right endpoints, and support your developers as they build.
➢ API and architecture advisory
➢ Feature-level support for HubSpot interoperability
➢ Developer support and code review
Ready to do more with your HubSpot integration?
While you may have your data integrated, you may want to do more with your integration than just syncing data. HubSpot offers a wide range of extensibility options that can enable your team to expand what's possible once your data is inside of HubSpot.
See how leading teams are enriching and activating data with custom integrations, like our Apollo to HubSpot integration that helped clients unlock GTM potential.
