customized HubSpot integrations: connect your tools and synchronize your data
Make your data work for your website and CRM on HubSpot
Would you like to integrate HubSpot with third-party tools?
If/else agency's developers design custom HubSpot integrations to connect your tools and automatically feed your statistics, CRM and website.
Custom connectors & API development on HubSpot
Why consider developing an API or custom connector on HubSpot?
Case 1: Native integrations don't go far enough, because you have very specific needs.
Case n°2: The applications made available are not those you use on a daily basis.
Case n°3: You have very specific business needs that require totally customized synchronization.
In just a few days, the if/else agency team can develop secure applications that connect your software to HubSpot and synchronize your data automatically in both directions.

Automate quote creation
Depending on the status of your transactions in CRM, we can execute code via a workflow to automatically generate quotations.

Migration
data migration
From one HubSpot account to another, or from a third-party CRM to HubSpot, we help you migrate your data cleanly and without loss.

Customer area and dedicated data
Can you retrieve your customers' invoices and display them in a dedicated space, or manage the sending of supporting documents for their files? HubSpot makes it possible.

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

Locator
Do you have several points of presence? Are your services or products spread across different territories? By synchronizing your tools with HubSpot, we can set up an interactive map on your site, dynamically displaying your offers wherever they are.

Public data
Would you like to use public data on your website or in your CRM? We connect HubSpot to external sources, process and standardize the necessary data, then integrate it seamlessly into your CRM and/or website.
Projects involving API integration and data synchronization between multiple tools can quickly become complex. To carry them out effectively, we rely on a clear, proven methodology. At if/else agency, we analyze your needs, design the data flow architecture, then set up reliable integrations so that your various systems communicate simply and sustainably with HubSpot.
Scoping workshops
We organize workshops with your teams to analyze your existing architecture, tools and data flows. This phase enables us to identify your needs and define the most appropriate technical solutions for integrating and synchronizing your systems with HubSpot.
Designing use cases
Together, we define the various synchronization and integration scenarios in the form of diagrams and data flows. This modeling enables us to validate the architecture and operating rules before launching development.
Integration development
We develop the API connections, HubSpot workflows and synchronization mechanisms needed to connect your tools to each other. Each integration is designed to ensure reliable, automated data flows tailored to your business processes.
Testing and production launch
We test integrations in real-life conditions with your teams, to check that flows and synchronizations are working properly. Once validated, we deploy the solution in production to guarantee stable, secure operation.

Generate dynamic pages from your HubSpot data
HubDB and CRM objects synchronized for automated content management
To deploy dynamic pages or directories on HubSpot, our teams create customized HubDB tables or CRM objects fed by your own data. These structures are then synchronized with your existing tools or databases to automate the feeding of information and become a single source of truth for your content.
Every new entry automatically generates a page, and every update is reflected in real time. The result is dynamic pages that are always up to date and perfectly aligned with your data.
The result: less manual management, greater reliability, scalability and efficiency.
Automate data synchronization with HubSpot
Automated data flows between HubSpot and your business tools
From a defined trigger (webhook) in HubSpot, we retrieve the data to be synchronized, structure it (ETL), then automatically transmit it to your third-party tools.
In other words, we set up workflows capable of automatically triggering, formatting and sending your data to your business tools.
if/else agency sets up reliable bidirectional (or unidirectional) data flows that enable your various systems to communicate with each other, without manual re-entry or loss of information.
HubSpot integrations: we create our own tools
Developed by developers,
guided by CRM expertise
As developers, we prefer customized tools to no-code solutions or generic connectors. We create reliable integrations tailored to your needs, which you retain full ownership of, with no dependence on a third party.
FAQ - HubSpot & back-end integrations
Frequently asked questions about HubSpot custom integrations
What is API synchronization with HubSpot?
API synchronization lets you connect HubSpot to other tools (CRM, ERP, customer support, etc.) to automatically share and update data between your systems. This ensures that all your teams are working with the same up-to-date information, without manual intervention.
What tools can I connect to HubSpot via API?
You can connect a wide variety of tools to HubSpot: CRM, ERP, billing tools, customer support, marketing platforms and more. Synchronization depends on the APIs available on these third-party tools and their compatibility with HubSpot.
What types of data can be synchronized?
Common data includes :
- Contacts: customer information, leads, segments.
- Transactions: deals, sales, opportunities.
- Events: interactions, support tickets, engagement histories.
- Custom data: any information specific to your company (products, orders, etc.).
Is data synchronization in real time?
Yes, synchronization can be performed in real time or at defined intervals, depending on your business needs. This enables you to react quickly to changes and automate your workflows.
Is my data secure during synchronization?
Yes, security is paramount. We use HTTPS protocols, OAuth 2.0 authentication and encryption mechanisms to guarantee data confidentiality and integrity during transfer.
Do I need a developer to configure synchronization?
Yes, API integration generally requires technical skills, especially in a bespoke framework. If you already have a team of developers, the if/else agency teams can intervene in the form of HubSpot technical consultants to train, guide and secure their technical choices within your new HubSpot ecosystem. If you don't have an in-house team, we can take charge of API development and integration to suit your needs.
Can I synchronize HubSpot with tools we already have in place (ERP, internal CRM, etc.)?
Absolutely. HubSpot has native connectors for some popular tools, but even for more specific or proprietary systems, we can develop custom APIs to ensure smooth synchronization.
What should I do if something doesn't work after synchronization?
If you'd like to implement it, we can help you with ongoing support to resolve any synchronization problems. In particular, by setting up a monitoring system to detect synchronization errors, we can intervene quickly to correct them.
What are the advantages of API synchronization over a manual solution?
API synchronization lets you :
- Avoid human errors associated with manual data entry.
- Save time by automating data updates.
- Improve the efficiency of your teams by accessing consistent, up-to-date data in real time.
- Offer a better customer experience thanks to automated processes and consistently relevant information.
