InterProse Sandbox Testing

What payment details can I use in sandbox?

InterProse processes payments through REPAY. In Sandbox, you can use REPAY's certification test cards. Most Visa and Mastercard numbers that pass a Luhn check will work; the following have been used extensively in REPAY's own testing and work across all of REPAY's documented test cases:

• Visa: 4111111111111111
• Mastercard: 5105105105105100

REPAY's certification test cases also define specific amounts that trigger particular approval, denial, AVS, and CVV outcomes.
