Q: When in sandbox mode, I get an error that says "Payment could not be authorized for the selected payment account. Please select a different account or try again." during checkout.
A: Please use the American Express test card from https://developer.authorize.net/hello_world/testing_guide.html Some of the other cards do not pass the regular expression card type checks as a real card would.
- Credit Card emails (e.g. Payment Approved (Credit Card)) may have missing content when payment is made without saving the details as a payment method. To help with this, replace "{card_type}" with "{card_type | set_default "credit card"}"and replace ", ending in {last_four}" with "{% if last_four %}, ending in {last_four}{% endif %}"
