Back-End Development & Custom HubSpot Integrations: Connect Your Tools and Sync Your Data

Leverage your data across your website and HubSpot CRM

Do you use HubSpot and want to integrate it with third-party tools?

Case #1: Native integrations don’t go far enough because you have very specific requirements.

Case #2: The available apps don’t match the tools you use every day.

Case #3: Your needs are highly specific and require fully custom data synchronization.

Whatever your situation, the developers at if/else agency design custom HubSpot integrations to connect your tools and automatically feed data into your analytics, CRM, and website.

Custom connectors & APIs on HubSpot

Why consider developing a custom API or connector for HubSpot

With 10 years of expertise on HubSpot and a constant commitment to making our work more understandable and accessible, we’ve compiled several real-world examples involving technical and custom development on HubSpot (back-end development, APIs).

In just a few days, the if/else agency team can build secure applications that connect your software to HubSpot and automatically synchronize your data in both directions.

Automate quote creation

Based on the progress of your deals in the CRM, we can run code through a workflow to automatically generate quotes.

Data migration

Whether from one HubSpot account to another or from a third-party CRM to HubSpot, we help you migrate your data smoothly and without loss.

Client portal & dedicated data

Retrieve your customers’ invoices to display them in a dedicated space, or manage the submission of supporting documents that make up their files, all of this is possible with HubSpot.

Custom ETL

We can develop a custom ETL (Extract, Transform, Load) to collect your data from multiple sources, transform and structure it, and then integrate it into your CRM according to your business rules and requirements.

Locator

Do you have multiple locations? Are your services or products distributed across different territories? By synchronizing your tools with HubSpot, we can set up an interactive map on your website to dynamically display your offers wherever they are located.

Public data

Want to leverage public data on your website or in your CRM? We connect HubSpot to external data sources, process and normalize the relevant data, and integrate it seamlessly into your CRM and/or your website.

HubSpot integrations and APIs: power your website and CRM with your data

How to display, synchronize,
and structure your data in HubSpot

Generate dynamic pages from your data in HubSpot

HubDB and CRM objects synchronized to automate your content management

To deploy dynamic pages or directories in HubSpot, our team creates HubDB tables or custom CRM objects tailored to your needs and powered by your own data. These structures are then synchronized with your existing tools or databases to automatically populate information and serve as a single source of truth for your content.

Each new entry automatically generates a page, and every update is reflected in real time. The result is dynamic pages that stay constantly up to date and perfectly aligned with your data.

The result: less manual management, greater reliability, scalability and efficiency.

Automate your data synchronization with HubSpot

Automated data flows between HubSpot and your business tools

Starting from a trigger defined in HubSpot, we retrieve the data to be synchronized, structure it (ETL) and automatically send it to your third-party tools.

In practice, we configure workflows capable of triggering, formatting, and automatically sending your data to your business tools.

if/else agency implements reliable bidirectional (or unidirectional) data flows, enabling your different systems to communicate with each other without manual re-entry or data loss.

How if/else agency designs robust HubSpot integrations

A structured approach to connect your tools, orchestrate your data, and secure your data flows in HubSpot

Projects involving API integrations and data synchronization across multiple tools can quickly become complex. To handle them effectively, we rely on a clear and proven methodology. At if/else agency, we analyze your needs, design the data flow architecture, and implement reliable integrations so your systems can communicate smoothly and sustainably with HubSpot.

The steps of a successful HubSpot integration and data synchronization

Scoping workshops

We run workshops with your teams to analyze your existing architecture, tools, and data flows. This phase allows us to identify your needs and define the most suitable technical solutions to integrate and synchronize your systems with HubSpot.

Use case design

Together, we define the different integration and synchronization scenarios using diagrams and data flow mappings. This modeling phase helps validate the architecture and operating rules before development begins.

Integration development

We build the API connections, HubSpot workflows and synchronization mechanisms required to connect your tools together. Each integration is designed to ensure reliable, automated data flows that align with your business processes.

Testing and deployment

We test the integrations in real-world conditions with your teams to ensure that data flows and synchronizations work as expected. Once everything is validated, we deploy the solution to production to guarantee a stable and secure setup.

FAQ – Custom integrations & back-end development on HubSpot

Frequently asked questions about custom HubSpot integrations

What is API synchronization with HubSpot?

API synchronization connects HubSpot with other tools (CRM, ERP, customer support platforms, etc.) to automatically share and update data across your systems. This ensures that all your teams work with the same up-to-date information, without manual intervention.

Which tools can I connect to HubSpot via API?

You can connect a wide range of tools to HubSpot, including CRM systems, ERPs, billing platforms, customer support tools, marketing platforms, and more. Data synchronization depends on the APIs available in these third-party tools and their compatibility with HubSpot.

For more advanced use cases, the if/else agency developers can also build custom integrations to retrieve and synchronize additional data sources.

What types of data can be synchronized?

Common data types include:

  • Contacts: customer information, leads, segments.
  • Deals: sales, opportunities, pipeline data.
  • Events: interactions, support tickets, engagement history.
  • Custom data: any business-specific information such as products, orders, or internal data.

Is data synchronization done in real time?

Yes, synchronization can be performed in real time or at scheduled intervals, depending on your business needs. This allows you to quickly react to changes and automate your workflows.

Are my data secure during synchronization?

Yes, security is a top priority. We use HTTPS protocols, OAuth 2.0 authentication, and encryption mechanisms to ensure the confidentiality and integrity of your data during transfer.

Do I need a developer to set up the synchronization?

Yes, API integrations generally require technical expertise, especially for custom implementations. If you already have a development team, if/else agency can step in as HubSpot consultants to support them, providing guidance, training, and helping secure the right technical decisions within your HubSpot ecosystem.

If you don’t have an internal team, we can handle the development and integration of the API based on your specific needs.

Can I synchronize HubSpot with tools we already use (ERP, internal CRM, etc.)?

Absolutely. HubSpot offers native connectors for some popular tools, but even for more specific or proprietary systems, we can develop custom APIs to ensure smooth and reliable data synchronization.

What should I do if something doesn’t work after synchronization?

If needed, we can provide ongoing support to resolve any synchronization issues. We can also implement monitoring systems to detect synchronization errors, allowing us to intervene quickly and fix them.

What are the benefits of API synchronization compared to a manual solution?

API synchronization on HubSpot allows you to:

  • Avoid human errors caused by manual data entry.
  • Save time by automating data updates across your systems.
  • Improve team efficiency by giving everyone access to consistent, up-to-date data in real time.
  • Deliver a better customer experience through automated processes and always-relevant information.

We build our own tools for your HubSpot integrations

Developed by engineers, guided by CRM expertise

As developers, we prioritize custom-built tools over stacking no-code solutions (often costly) or relying on generic connectors that lack the specificity many projects require. We build our own tools to create reliable integrations tailored to our clients’ needs. The code we develop belongs to you: you remain the full owner of your integrations, with no dependency on third-party solutions or external providers.
