Suitable for static websites or simple HTML pages. ### Supported Ad Formats * Banner Ads * Native Ads (with custom UI support) ### Requirements * Modern browsers (Chrome, Firefox, Safari, Edge) *** ## Installation Add the script to the `` section of your HTML document. ```html theme={null} ``` To lock to a specific version, specify the version number instead of `@latest`. Example: `@adrop/ads-web-sdk@1.0.1` *** ## Initialization Initialize the SDK after the script loads. ```html theme={null} ``` ### Initialization Options (AdropConfig) App ID issued from Ad Control Console User identifier (used for targeting) API authentication key (required for updating user properties) Enable debug logging Publisher-wide backfill rendering mode. Per-slot overrides take precedence. See the [Backfill Rendering Mode](/sdk/web/backfill) guide for details. (SDK 1.2.3+) Set `debug: false` in production environments. ### Instance Access After initialization, you can access the SDK from anywhere using `Adrop.instance()`. ```javascript theme={null} const adrop = Adrop.instance(); // Use SDK ``` ### Dynamic Configuration Updates You can change settings at runtime, such as setting a user ID after login. ```javascript theme={null} // Using setters Adrop.instance().uid = 'USER_ID'; Adrop.instance().appKey = 'YOUR_APP_KEY'; // Or using setConfig Adrop.instance().setConfig({ uid: 'USER_ID', appKey: 'YOUR_APP_KEY' }); ``` For targeted ads to work properly, set `uid` before rendering the ad placement. *** ## WebView Setup (For Backfill Ads) If your web app runs in a WebView and you want to display backfill ads, you need to configure the native app. See the platform-specific guides below.
