This is an example of testing the Cart Funnel, but the process is similar. If you also have not added in the workflow and pipeline, it's alright, you can ignore those portions at the moment.
When testing interactively, use a card number, such as 4242 4242 4242 4242. Enter the card number in the Dashboard or in any payment form.
- Use a valid future date, such as 12/34.
- Use any three-digit CVC (four digits for American Express cards).
- Use any value you like for other form fields.
