Sandbox Payment Gateway eliminates the need to create coupons or configure real payment gateways when testing your WooCommerce checkout. It provides two fake payment methods that simulate real checkout behavior without processing any actual payments.
Sandbox Credit Card
Accepts any valid credit card number with Luhn algorithm validation, expiry date checks, and CVV verification.
Sandbox ACH / eCheck
Accepts check name, routing number (9 digits), and account number (4-17 digits). Successful payments are placed on-hold to simulate real-world eCheck verification.
Simulating a successful credit card transaction
Use any valid credit card details (e.g. card number 4111111111111111).
Simulating a failed credit card transaction
Use card number 4929000000022 with a valid expiry and CVV.
Simulating a successful eCheck transaction
Use any valid 9-digit routing number and 4-17 digit account number.
Simulating a failed eCheck transaction
Use routing number 000000000 with any valid account number.
Refunds
Both gateways support refunds from the WooCommerce admin order page. Since payments are simulated, refunds simply log a note on the order.
Development
