STRIPE-Supabase-Lindy.ai-PostHog-Build.io Integration

Here’s an expanded scope to include connecting Stripe to your Supabase database, Lindy.ai agents, PostHog analytics, and the Builder.io control panel:

1. Supabase Integration
- Update `compliance_scans` and user tables with `stripe_customer_id`, `stripe_subscription_id`, `subscription_tier`, and `subscription_status`.
- Build Supabase Edge Function to receive Stripe webhooks and update customer records.
- Trigger Lindy.ai agent workflows (onboarding, tier changes, access enabling, offboarding) via secure webhooks from Supabase.

2. Lindy.ai Agent Triggers
- Configure each relevant Stripe event (`subscription.created`, `subscription.updated`, `invoice.paid`, `invoice.failed`, `subscription.deleted`) to send a JSON payload to Lindy.ai agent webhooks.
- Payload includes customer ID, new tier, compliance scan ID, and subscription metadata.
- Ensure retry logic and error handling in Edge Functions for reliable delivery.

3. PostHog Analytics
- Track Stripe payment events and subscription lifecycle in PostHog:
– `subscription_started` with properties: tier, amount, currency, compliance score
– `subscription_upgraded` with from_tier, to_tier, revenue_delta
– `payment_failed` with tier, failure_reason, retry_count
- Implement client- and server-side event capture in the control panel and Edge Functions.

4. Builder.io Control Panel Connectivity
- Expose REST endpoints to retrieve current subscription status and tier for logged-in users via Supabase function.
- Update control panel UI to show active tier, next billing date, and allow manual cancellation or upgrade.
- Listen to Supabase real-time subscription updates via WebSocket or Server-Sent Events and refresh the dashboard automatically.
- Secure endpoints with role-based access control and user authentication.

5. Environment & Deployment
- Ensure Netlify environment variables include: STRIPE_CLIENT_ID, STRIPE_SECRET_KEY, STRIPE_PUBLISHABLE_KEY, STATE_SECRET, STRIPE_ENABLED, CORS_ORIGIN.
- Configure Supabase and Lindy.ai webhook secrets in environment variables for secure verification.
- Validate PostHog write key and host in environment.

6. Testing & Validation
- Perform end-to-end tests: subscription purchase → Supabase record update → Lindy.ai agent invocation → control panel status update → PostHog event logged.
- Test upgrade, downgrade, cancellation, and payment failure scenarios.
- Verify data consistency across Supabase, Lindy.ai logs, and control panel UI.

This completes the full integration of Stripe payments with your Supabase backend, Lindy.ai agent workflows, PostHog analytics, and the existing Builder.io control panel.
