How 3D Secure Works with Instant Accept
When a cardholder checks out, 3D Secure pops up an extra verification screen—often a one-time passcode or biometric approval. Here’s how Instant Accept integrates it without slowing things down:
- Seamless API call: Your checkout triggers a 3D Secure request in real time.
- Dynamic challenge flow: Based on the card issuer’s risk assessment, customers may see a simple “approve” button or enter a code sent to their phone.
- Instant confirmation: Once authenticated, funds flow into your accounting system, eliminating duplicate entries.
Benefits of 3D Secure Authentication

Fraud reduction
Verified cardholders mean fewer chargebacks.

Higher approval rates

Improved customer confidence
Shoppers feel safer when they see extra protection at checkout.
