👋 **Hey HubSpot Developers!**
I'm working on an insurance comparison platform and need some guidance on creating a custom CRM card.
**What we've built so far:**
✅ OAuth integration allowing users to login to our app via HubSpot
✅ Angular frontend + FastAPI backend
✅ User management with HubSpot user sync
**What we need help with:**
🎯 Creating a **custom CRM card** that displays within HubSpot contacts/deals with a button that redirects users to our comparison tool
**The use case:**
- Insurance brokers using HubSpot CRM
- When viewing a contact/deal, they see our CRM card
- Click button → opens our comparison tool in new tab with context from HubSpot
**Questions:**
1. What's the best approach for CRM cards - serverless functions or hosted app?
2. How do we securely pass contact/deal data to our external tool?
3. Any examples of similar integrations you've seen?
**Tech stack:** Angular, FastAPI (Python), already have HubSpot OAuth working
Would really appreciate any guidance, code examples, or pointing me toward the right docs! 🙏
