Summary

Complete fix for Polar webhook integration issues that were preventing subscription sync after payment completion.

Problems Solved

  • 307 Redirect Issue: Updated webhook URL to use correct production domain (https://www.convertiq.cloud)
  • 401 Authentication Errors: Added handlers for all Polar webhook event types
  • Missing Subscription Records: Implemented order.paid event handler for subscription creation
  • Unhandled Events: Added comprehensive event handling for all possible Polar webhooks

Key Changes

  • Enhanced webhook handler (/src/app/api/webhooks/polar/route.ts):

    • Added order.paid event handler that creates subscription records
    • Added handlers for customer, checkout, order, refund, and informational events
    • Enhanced subscription status change handling for active/uncanceled/revoked states
    • Comprehensive error handling and logging
  • Admin recovery tools:

    • Webhook setup endpoint for automated configuration
    • Manual trigger utilities for missed webhooks
    • Enhanced subscription service with metadata fallbacks

Technical Details

  • Root Cause: Polar sends order.paid events (not subscription.created) for new subscriptions
  • Solution: Extract subscription data from order events and process via existing logic
  • Event Coverage: Now handles all 25+ possible Polar webhook event types
  • Metadata Handling: Smart fallback logic when webhook metadata is missing

Testing

  • Webhook URL configuration updated in Polar dashboard
  • All webhook event types now return 200 responses
  • Subscription creation tested with order.paid events
  • Customer and order events processed without errors

Impact

  • ✅ Users will now see subscription plans correctly after payment
  • ✅ No more webhook processing failures or 401/307 errors
  • ✅ Comprehensive audit trail of all subscription lifecycle events
  • ✅ Robust fallback mechanisms for webhook metadata issues
