How do I trigger a decline in Authorize.net sandbox?

Authorize.net sandbox uses transaction amounts to trigger declines, not separate card numbers. Use $0.02 for generic decline, $0.08 for do not honor, $0.21 for insufficient funds, $0.41 for expired card. The success card (4111...) with $0.01 or any normal amount returns an approval.

Does Authorize.net support 3DS?

Authorize.net supports cardAuthentication for 3DS, but the sandbox implementation is limited compared to providers like Stripe or Adyen. Consult the Authorize.net developer docs for their current 3DS testing guidance.

Is Authorize.net still widely used?

Authorize.net is still used by a large number of US businesses, particularly in enterprise and legacy systems. It processes a significant volume of US transactions, especially through integrations built in the 2000s-2010s that haven't migrated to newer providers.

What it does

13-digit Visa support

Authorize.net accepts 13-digit Visa numbers in addition to standard 16-digit — useful for testing legacy format handling.

Multi-network cards

Test cards for Visa (16 and 13 digit), Mastercard, Mastercard 2-series, Amex, and Discover.

Amount-based decline simulation

Authorize.net simulates declines using specific amounts ($0.02, $0.21, etc.) rather than separate card numbers.

Legacy US payment gateway

2

Any future expiry date and any CVV work with these test cards in sandbox mode.
3
Simulate declines with amounts
To simulate declines in Authorize.net sandbox, use $0.02 (generic decline), $0.08 (do not honor), or $0.21 (insufficient funds) instead of a specific card number.
4
Check the response code
Authorize.net returns a response_code (1=Approved, 2=Declined, 3=Error) and a response_reason_code.

Authorize.net's amount-based decline simulation

Unlike Stripe, Adyen, and Braintree which use specific card numbers to trigger declines, Authorize.net's sandbox primarily uses transaction amounts. You submit the success card (4111 1111 1111 1111) but with a specific dollar amount like $0.02 to get a decline response. This is Authorize.net's documented approach for sandbox testing and reflects the older design of their test environment.
