Daou payment window integration guide

1. Configure Daou PG settings

Refer to the Daou settings page to configure the PG settings.

2. Request payment

To open the payment window, call JavaScript SDK IMP.request_pay(param, callback).

In PC browsers, callback is invoked after calling IMP.request_pay(param, callback). In mobile browsers, the page is redirected to m_redirect_url.
