Decline and approval-rate troubleshooting signals

Surfaces common response codes and transaction details to help diagnose card declines. Can support testing and optimization with your processor.

Security and PCI support options

Offers tokenization-style features and hosted payment options that can reduce PCI scope. Security controls depend on integration method.

Authentication and verification controls

Includes verification settings (for example, AVS/CVV) and can support merchant authentication requirements based on processor/card brand rules.

Dispute and refund workflows

Tip from SmartRetry If you’re seeing higher card declines, review AVS/CVV settings and decline codes with your processor first, then adjust rules to avoid over-filtering legitimate buyers.

FAQ

Authorize.Net is a payment gateway used by merchants to accept and manage card (and some bank-account) payments across online, mobile, and in-person channels.
Authorize.Net is primarily a payment gateway; you typically still need a merchant account/processor (acquirer) to actually process card payments and fund settlements.
It can help you diagnose declines by exposing response codes and verification results, but approval rates are also driven by your processor, card issuer decisions, and your fraud/verification settings.
Common causes include issuer declines, AVS/CVV mismatches, fraud settings that are too strict, formatting/data issues, or processor configuration. Use the decline reason code and your processor support to pinpoint the cause.
Yes, it supports recurring and subscription-style payments depending on your account setup and integration choices.
