webMethod( )

Defines a backend function that can be called from the frontend.

Description

The webMethod() function is a wrapper used to export functions from backend code that can be called from the frontend. Use the function's first parameter to define the permissions needed to call the function in frontend code. You can import the Permissions enum from the wix-web-module module to define the permissions. The permission options are:

Permissions.Anyone: Any site visitor can call the function.
Permissions.Admin: Only site admins can call the function.
Permissions.SiteMember: Only site members can call the function.

Web methods must be defined in files with a .web.js extension.
