Bridge the gap between your custom website and HubSpot CRM with intelligent GitHub API connections that create a seamless two-way data flow preserving attribution accuracy and technical control.
Many companies using HubSpot as their CRM platform face a fundamental challenge: they're forced to choose between HubSpot's native marketing tools (forms, pages, emails) and maintaining control over their website's code ecosystem. This compromise creates data silos, attribution gaps, and limited customization that undermine marketing effectiveness and customer insight.
At Byer Co, we've developed a proprietary integration solution that bridges this gap through intelligent GitHub API connections, creating a seamless two-way data flow between your custom website and HubSpot CRM.

Contacts created via integrations like Shopify typically show as "Offline Integration" rather than accurately reflecting their actual acquisition channels (Paid Search, Direct, etc.). This occurs because standard integrations bypass HubSpot's tracking code, which captures essential UTM parameters and referral data.
Embedded HubSpot forms can experience intermittent sync failures with the CRM, creating data gaps and affecting lead management effectiveness. These issues often stem from cookie conflicts, browser settings, or form implementation errors.
HubSpot's native forms and pages operate within constrained templates that limit brand expression, user experience optimization, and advanced functionality that custom-coded websites can provide.
Standard implementations create data separation between website analytics and CRM data, making it difficult to track the complete customer journey from first touch to conversion.


We believe that when you own your entire code ecosystem and establish intelligent data bridges between systems, both platforms become more powerful. Your website gains CRM intelligence, while HubSpot gains complete visitor data typically lost in standard implementations.
Custom form handlers intercept submissions from any website form. Data validation and enrichment occurs before transmission. Progressive profiling logic ensures optimal data collection without redundant field requests.
Event-based tracking captures specific user interactions (button clicks, video views, document downloads). Page engagement metrics track time on page, scroll depth, and content interaction.
Complete UTM parameter capture from all inbound links. Referral source tracking with domain-level granularity. Campaign attribution across multiple touchpoints.
API calls to HubSpot's Contacts and Events APIs. Webhook implementations for immediate data updates. Batch processing for high-volume scenarios with error handling and retry logic for data integrity.
Contact recognition for returning visitors. Personalized content based on lifecycle stage, interests, or past behavior. Dynamic CTAs that reflect known contact properties and recommendation engines leveraging CRM data.
Workflow-initiated content changes based on contact properties. List-based experiences for segmented audiences. Timed content releases synchronized with email campaigns and A/B test variations informed by CRM data.
Website analytics augmented with CRM stage data. Conversion reporting tied to actual deal progression. ROI calculation connecting website interactions to revenue with complete funnel visibility.


GitHub Actions workflows automatically deploy code changes to production. Environment-specific configurations for staging and production with automated testing before deployment and rollback capabilities for rapid issue resolution.
Version control for all integration components. Team collaboration through GitHub's development features with documentation synchronization and audit trails for compliance and troubleshooting.
Centralized repository for all HubSpot integration code. Modular architecture for easy updates and maintenance. Configuration management separate from business logic with secure secret management for API keys and credentials.
