Test Card Numbers
Use test card numbers to test your Stash Pay and Stash Webshop integrations. These test cards work with Stash's test environment and Stash Howling Woods demo.
Important: Test cards do not create real charges. All transactions using these test card numbers are processed in Stash's test environment and will never result in actual payment processing or charges to any real payment method.

Understanding Test Transactions
How Test Cards Work
Test cards are special card numbers that Stash recognizes as test transactions. When you use these cards:
- No real charges occur - These transactions never process through actual payment networks
- Test environment only - All test transactions are isolated to Stash's test environment
- Safe for development - You can test your integration repeatedly without financial risk
- Webhooks still fire - Test transactions trigger webhooks in your test environment, allowing you to verify your webhook handling logic
Verifying Test Purchases
To verify that a test purchase completed successfully:
- Check webhook logs - Your webhook endpoint should receive a
PURCHASE_SUCCEEDEDevent - Query payment status - Use the Get Payment Event API to check the payment status
- Review Stash Studio - Test transactions appear in your Stash Studio dashboard with a test indicator
Test vs Production Environments
Test Environment:
- Use test cards (listed on this page) for all testing
- Test cards are processed in Stash's test environment
- No real charges occur - transactions are completely isolated
- Test cards will be rejected if used in production
Production Environment:
- Use real, live payment cards from your customers
- Real cards are processed through actual payment networks
- Real charges occur - customers are charged for purchases
- Test cards will not work and will be rejected
Important: Always verify you're connected to the correct environment (test vs production) before processing any transactions. Check your API endpoints and Stash Studio configuration to confirm which environment you're using.
Environment Requirements:
- Test/Development/Staging environments: Use test cards only. Never use real card numbers in test environments.
- Production environment: Use real, live payment cards only. Test cards will not work in production and will be rejected.
Always verify you're using the correct environment before testing or processing payments.
