WeChat Pay

About this Document

Users pay for goods or services in Mini Programs created inside WeChat.
Mini Programs are especially suitable for diverting users from offline stores to online shopping. This breaks down geographical barriers and encourages users to make repeat purchases.
Merchants accept payments in a Mini Program by calling the WeChat Mini Program payment API. WeChat users open the merchant’s Mini Program, place an order, enter their payment password to complete the payment, and then return to the merchant's Mini Program.

About the detailed Mini Program Pay , please refer to Product introduction
