WeChat Pay

Intro

WeChat Pay is a Chinese payment feature integrated into the WeChat app. More than 900 million customers use it at least once a month for easy and quick smartphone payments. Your customers pay in CNY, but you will receive the settlement in your local currency.

The integration is very easy and enables your customers to pay swiftly: You send a standard request to our platform to redirect your customers to the WeChat portal, opening their mobile app to confirm the payment.

Your customers need a wallet in the WeChat application linked to a Chinese bank account.
