How can I test transactions on my Webflow Ecommerce site before launching, specifically with regards to UK card numbers and potential issues with Stripe's test card numbers?

When testing transactions on your Webflow Ecommerce site, you can use Stripe's test mode along with their test card numbers to simulate transactions without actually charging any real credit cards. To test transactions specifically for UK card numbers, you can use the following test card numbers provided by Stripe:

- Visa: 4242 4242 4242 4242
- Mastercard: 5555 5555 5555 4444
- Amex: 3782 822463 10005
- Discover: 6011 1111 1111 1117

To enable test mode in Webflow, follow these steps:

1. Log in to your Webflow account and select your Ecommerce project.
2. In the Designer, go to the Ecommerce tab on the left sidebar.
3. Click on the "Settings" tab and scroll down to the "Payment Providers" section.
4. In the Stripe section, click on the "Enable test mode" toggle switch.

Now that you have enabled test mode, you can simulate various scenarios and potential issues by using the test card numbers provided. Here are a few scenarios you can test:

• Successful transactions: Use the test card numbers with any other valid test data (e.g., future expiry date, any three-digit CVC code) to simulate successful transactions. This will help you ensure that your checkout process works smoothly.
• Declined transactions: Use the specific card number for declined transactions in Stripe's documentation (e.g., 4000 0000 0000 0002) to verify that your site handles declined payments correctly.
• Incorrect card details: Use an incorrect card number or incorrect CVC code along with a future expiry date to test how your site responds to incomplete or invalid payment information.
• Payment errors and error handling: Trigger specific error codes by using specific test card numbers listed in Stripe's documentation (e.g., 4000 0000 0000 0119 to simulate incorrect CVC). This will allow you to test how your site handles different error scenarios and displays appropriate error messages to users.

Remember to perform thorough testing in test mode before launching your site to ensure a smooth customer experience. It's also a good idea to test with different browsers and devices to ensure compatibility and usability across all platforms.

Additionally, Stripe provides detailed documentation on their testing environment and various test card numbers for different scenarios. You can refer to their documentation for more information and additional test card numbers if needed.

Keep in mind that this information is accurate as of this post. Stripe's test card numbers and test environments may have changed since then, so it's always a good idea to check their official documentation for the most up-to-date information.
