# Optimize payment flow while reducing code complexity with Stripe's A/B Testing

## Summary

Payment method choices affect ecommerce conversion, and the post notes that 81% of surveyed customers frequently abandon carts when their preferred method is unavailable. It explains how Stripe’s dynamic payment methods in Elements and Dashboard settings can apply country, region, and amount rules without embedding those conditions in PaymentIntent code. The proposed workflow uses Dashboard experiments to enable methods such as Klarna, set display rules and traffic allocation, then uses Workbench Inspector, Logs, and Events tabs to inspect presented payment\_method\_types, API requests, and webhook history. A Klarna example reports a 16% increase in average order value, while new payment methods were deployed within four days.

## Context

Businesses may hesitate to change payment methods because poorly implemented adjustments could reduce sales, while hard-coded country, currency, and amount conditions increase maintenance, pre-release testing, deployment requirements, and troubleshooting difficulty.

## Approach / What changed

Use Stripe Elements with dynamic payment methods configured in the Dashboard, then run controlled Dashboard experiments with selected payment methods, display rules, and traffic percentages. Use Workbench Inspector, Logs, and Events to inspect payment methods, creating API requests, and related webhook data for investigation and debugging.

## Takeaways

- Stripe’s dynamic payment method settings can apply geographic and amount-based rules from the Dashboard instead of requiring equivalent conditional logic in application code.
- A/B experiments can enable methods such as Klarna for a selected percentage of payment traffic, with 50% as the default and lower allocations such as 30% available.
- Workbench provides resource JSON, API request logs, and webhook event history for investigating which payment methods were presented and how a PaymentIntent was created.
