Sample Codes

For the convenience of your integration process, we have prepared multiple sets of sample codes for your reference.

Android App

For the merchants who integrate with mobile app, we have created a demo application with sample codes for reference. Detailed setup can be found in the Github page.

PHP

Below is sample code for requesting create hosted checkout: /hosted-checkout/create as a reference.
