How do I localize a checkout by country?

Make one call at the start of a session. It returns the buyer's currency and its exact formatting, their locale, the correct tax treatment, and the payment methods that market actually uses — everything the page needs so nothing reads as foreign, from a single request.

Does showing local currency actually reduce cart abandonment?

Buyers who see their own currency, formatted the way they read it, and a payment method they recognise are far less likely to bounce at checkout. Localising the money layer is one of the highest-leverage changes you can make to a cross-border funnel.

Do I need separate APIs for currency, tax and payments?

No — that is the point. Currency formatting, tax rate and display rule, and local payment methods all come back in one LocaleSense response, so you localize the whole checkout without stitching several vendors together.

Checkout localization — LocaleSense

A checkout that speaks the local language of money converts better. One call at the start of a session returns the currency and its exact formatting, the locale, the tax treatment and the payment methods that market actually uses — so nothing on the page reads as foreign.

Why it works_

The highest-leverage call in your funnel

Right currency, right format

Prices render the way locals read them, down to decimals and separators.

Right payment methods

Surface iDEAL, Pix or cash-on-delivery where they dominate instead of a generic card form.

Right tax display

Inclusive or exclusive, at the correct rate, per law.

The data behind it
