To enable payment processing with Visa/Mastercard, you'll need to set up Stripe:

1. Go to stripe.com and create an account
2. Complete the account verification process
3. Navigate to the Dashboard

1. In the Stripe Dashboard, go to Developers → API keys
2. Copy your Publishable key (starts with pk_)
3. Copy your Secret key (starts with sk_)

1. Go to your Val Town settings
2. Add these environment variables:
   • STRIPE_PUBLISHABLE_KEY: Your Stripe publishable key
   • STRIPE_SECRET_KEY: Your Stripe secret key

1. In Stripe Dashboard, go to Developers → Webhooks
2. Add endpoint: https://your-val-town-url.web.val.run/api/payments/webhook
3. Select events: payment_intent.succeeded
4. This ensures trainers are marked as sold when payments complete

1. In your Stripe Dashboard, go to Settings → Payouts
2. Add your bank account details where you want to receive payments
3. Stripe will handle the transfer of funds to your account

Stripe supports many countries. Check Stripe's supported countries to ensure your location is supported.

• Stripe starts in test mode by default
• Use test card numbers like 4242 4242 4242 4242
• No real money is processed in test mode

1. Complete Stripe's verification process
2. Switch to live mode in your Stripe Dashboard
3. Update your environment variables with live keys (they'll start with pk_live_ and sk_live_)

• Never expose your secret key in client-side code
• The current implementation uses a simplified payment flow
• For production, consider implementing additional security measures like webhook signature verification
