Writing a Sub-plugin for MPSS

Sub-plugins extend MPSS functionality to support specific e-commerce platforms. They act as bridges between MPSS and the target platform, handling stock synchronization and platform-specific operations.

Minimum Requirements

A basic MPSS sub-plugin must:

• Register itself with MPSS
• Implement stock change reporting
• Handle stock updates from MPSS
• Follow MPSS data exchange standards
• Follow the WordPress detailed plugin guidelines
• Pass all the plugin check tests.

However, the plugin may include many additional features specific to that platform, which are unrelated to MPSS. Furthermore, while MPSS is free to use, the sub-plugins may be either free or paid, and may operate under a different license—this is entirely at the discretion of the plugin developers.
