What it does
On this page The Manifest file The manifest.json file is the core configuration file for your Overwolf app. It defines essential app properties including metadata, permissions, window configuration, game targeting, and runtime behavior. The file is mandatory and must be located in the root folder of your app. info For a complete, working example of a manifest.json file, see the Overwolf sample app . Minimum manifest.json example This example shows a minimal, valid manifest.json file with required fields only: { "manifest_version" : 1 , "type" : "WebApp" , "meta" : { "name" : "My App" , "author" : "My Company" , "version" : "1.0.0" , "minimum-overwolf-version" : "0.170.0" , "description" : "A brief description of my app" , "icon" : "assets/icon.png" } , "data" : { "start_window" : "main" , "windows" : { "main" : { "file" : "index.html" } } } } note This is the minimum required to pass schema validation. For Appstore submission you also need dock_button_title , icon_gray , launcher_icon , and window_icon — see the meta properties table for details. Validate your manifest.json To ensure your manifest file is correct and complete, validate it against the official schema. Read the schema validation best practices for detailed validation instructions.
