Hello HubSpot Community,
I’ve developed an open-source Flutter plugin intended to help developers integrate HubSpot CRM APIs into mobile applications.
This is an early-stage developer project, and I’m currently looking for feedback and real-world validation.
Subscription level: Open Source (Free tools)
Project status: Early implementation phase
Current scope:
Designed OAuth 2.0 flow for public mobile apps
Implemented core Flutter wrapper structure
Preparing for end-to-end API validation
I’m looking for:
Feedback on OAuth architecture for mobile-native apps
Guidance on recommended security patterns (direct mobile vs backend proxy)
Developers willing to test, build, or experiment with the plugin
Suggestions to make the integration more robust and production-ready
Technical reference:
If anyone is interested in testing or building something with it, I would greatly appreciate your feedback. My goal is to ensure the architecture aligns with HubSpot’s best practices before moving toward broader adoption.
Thank you in advance for your insights.
