🧹 Cleanup Old Stripe Functions

Overview

Since we're now using @supabase/stripe-sync-engine, we need to remove the custom webhook handler functions that were created by the old sql/36_stripe_webhooks.sql file.

✅ What's Been Done

Files Deleted

• ✅ api/src/stripe-webhook.ts - Custom webhook handler (replaced by library)
• ✅ sql/36_stripe_webhooks.sql - Custom webhook SQL functions (replaced by library)

Files Updated

• ✅ api/src/stripe.ts - Now uses StripeSync library
• ✅ apps/main/src/hooks/stripe.ts - Uses stripe schema
• ✅ sql/35_stripe_wrappers.sql - Uses stripe schema, updated function references

🗑️ Cleanup Database Functions

Run this SQL to remove the old custom functions:

\i sql/cleanup_old_stripe_functions.sql

Or run manually:

-- Drop old custom webhook handler functions
drop function if exists public.handle_stripe_customer_created(text, text, uuid);
drop function if exists public.handle_stripe_customer_updated(text, text);
drop function if exists public.handle_stripe_customer_deleted(text);
drop function if exists public.handle_stripe_product_upsert(text, text, text, boolean, text, jsonb);
drop function if exists public.handle_stripe_product_deleted(text);
drop function if exists public.handle_stripe_price_upsert(text, text, boolean, text, bigint, text, integer, integer, jsonb);
drop function if exists public.handle_stripe_price_deleted(text);
drop function if exists public.handle_stripe_subscription_upsert(text, text, text, text, integer, boolean, timestamp with time zone, timestamp with time zone, timestamp with time zone, timestamp with time zone, timestamp with time zone);
drop function if exists public.handle_stripe_subscription_deleted(text);

✅ Verify Cleanup

Run this to check if old functions are gone:

SELECT routine_name
FROM information_schema.routines
WHERE routine_schema = 'public'
  AND routine_name LIKE 'handle_stripe_%';

Should return 0 rows.

✅ Verify Kept Functions

These functions are still needed and should exist:

SELECT 
  routine_schema,
  routine_name
FROM information_schema.routines
WHERE routine_schema IN ('public', 'stripe')
  AND routine_name IN (
    'is_paying_user',
    'get_user_subscription_status',
    'get_user_stripe_customer_id',
    'sync_subscription_user_id',
    'update_profile_subscription_status',
    'update_updated_at_column'
  )
ORDER BY routine_name;

Should return 6 rows (all the functions we still use).

📋 Migration Order

For a fresh setup:

1. Run stripe-sync-engine migrations

   import { runMigrations } from '@supabase/stripe-sync-engine';
   await runMigrations({ databaseUrl: process.env.DATABASE_URL });
   

   Creates stripe schema and all base tables

2. Run custom SQL

   \i sql/35_stripe_wrappers.sql
   

   Adds user_id, RLS, triggers, helper functions

3. (Optional) Run cleanup if old functions exist

   \i sql/cleanup_old_stripe_functions.sql
   

   Removes old custom webhook handlers

🎯 What Each Function Does

Functions We Keep (In public schema):

Function	Purpose	Used By
is_paying_user(uuid)	Check if user has active subscription	Frontend queries
get_user_subscription_status(uuid)	Get subscription details	Optional
get_user_stripe_customer_id(uuid)	Get Stripe customer ID	API endpoints
update_profile_subscription_status()	Trigger: Update profile.is_paying	Automatic
update_updated_at_column()	Trigger: Update timestamps	Automatic

Functions We Keep (In stripe schema):

Function	Purpose	Used By
sync_subscription_user_id()	Trigger: Populate user_id in subscriptions	Automatic

Functions We Removed:

Function	Why Removed
handle_stripe_customer_*	✅ Library handles it
handle_stripe_product_*	✅ Library handles it
handle_stripe_price_*	✅ Library handles it
handle_stripe_subscription_*	✅ Library handles it

🎉 Result

Before:

• Custom webhook handlers: 9 functions
• Custom webhook processing code: 267 lines (TypeScript)
• Custom SQL functions: 315 lines

After:

• Library handles all webhooks automatically
• Custom functions: 6 (only for profile integration)
• Total custom code: ~150 lines

Reduction: ~80% less code to maintain! 🎊

📝 Summary

✅ Old webhook handler functions removed
✅ stripe-sync-engine library integrated
✅ All code updated to use stripe schema
✅ RLS policies in place
✅ Helper functions preserved
✅ Triggers working
