A client approached us to integrate Cybersource—a robust payment management platform—with their HubSpot-hosted software product. At the time, HubSpot lacked native support or any marketplace app for Cybersource. To overcome this limitation, we developed a custom bridge using modern development tools and APIs that enabled secure payment processing and automatic synchronization of transaction data within HubSpot.
This North America-based fintech, serving top-tier banks with AI-powered pricing tools, found itself caught between market expectations and legacy architecture. While customers expected instant responsiveness, the provider’s own systems remained bound to manual release cycles, code-heavy processes, and sprawling technical debt.
The client needed all product purchases to be processed through Cybersource while retaining HubSpot as their primary CRM and website platform. However, HubSpot didn’t offer built-in support for direct payment gateways or subscription handling. The main goals included:
We created a custom integration using a lightweight PHP-based server to serve as a bridge between the two platforms. When a user initiates a purchase, they are securely redirected to Cybersource’s hosted checkout. Upon payment completion, transaction data is sent back through our server and injected into HubSpot using its API, ensuring the customer journey remains cohesive and fully automated.
“We needed something that didn’t exist — and the team made it happen. The integration works flawlessly, and we finally have a system where HubSpot and Cybersource talk to each other without a hitch. It’s saved us time, reduced errors, and made the user experience so much better. ”
