Online PC/Mobile Web Payment

POST 
/api/entry/unifiedorder

The merchant calls this API in online scenarios to generate a pre-payment transaction order in the PayCloud service backend and initiates web payment based on the returned checkout URL or payment parameters.

1. For WeChat and Alipay+, this API can only be called when the webpage is opened in the mobile default browser or some third-party browsers.
2. Only the online store number store_no can be used to call this API.
3. For WeChat H5 payment, please call this API.
4. terminal_type = WEB is PC web payment; terminal_type = WAP is mobile web payment.
5. Although the parameters term_ip, longitude, and latitude are currently optional, considering that they may become mandatory in the future for risk control purposes, it is recommended to set these parameters in advance to prepare for potential changes.

For more details, please refer to PC Web Payment and Mobile Web Payment.
