The `page` event records whenever a user views a page on your website or a screen in your mobile app. Both the [web SDK](/sdks/web) and [mobile SDK](/sdks/mobile) emit `page` events with `channel` set to `"web"` or `"mobile"` respectively. On web, page properties are automatically collected from the browser. On mobile, the screen name is mapped to page-equivalent fields (`page_title`, `page_path`, `page_url`) so that web and mobile views are processed through the same analytics pipeline. ## Properties | Property | Type | Description | Web SDK | Mobile SDK | | :--------- | :----- | :-------------------------------------------------------- | :------------------------- | :--------------------- | | `url` | String | Full URL of the page. | `window.location.href` | Not set | | `path` | String | Path component of the URL (without query string or hash). | `window.location.pathname` | Not set | | `hash` | String | Hash fragment of the URL (e.g., `#section`). | `window.location.hash` | Not set | | `query` | String | Query string of the URL (without the leading `?`). | `window.location.search` | Not set | | `name` | String | Name of the page or screen. | Caller-provided | Screen name (required) | | `category` | String | Category of the page or screen. | Caller-provided | Caller-provided | | `title` | String | Title of the page. | Caller-provided | Not set | On web, any non-UTM query-string parameters are also added as individual properties. The SDKs additionally auto-collect the following context fields: | Context field | Web SDK | Mobile SDK | | :---------------------------- | :---------------------------- | :--------------------------------------- | | `context.page_url` | `window.location.href` | `app://{screenName}` | | `context.page_title` | `document.title` | Screen name | | `context.page_path` | Not set (derived in backend) | Not set (derived in backend) | | `context.referrer` | `document.referrer` | From deep link (if set) | | `context.user_agent` | Browser user agent | Device user agent (if available) | | `context.locale` | Browser language | Device locale | | `context.timezone` | Resolved IANA timezone | Resolved IANA timezone | | `context.location` | Country derived from timezone | Country derived from timezone | | `context.library_name` | `"Formo Web SDK"` | `"Formo React Native SDK"` | | `context.library_version` | SDK version | SDK version | | `context.browser` | Detected browser name | Not set | | `context.screen_width` | `window.screen.width` | `Dimensions.get("screen").width` | | `context.screen_height` | `window.screen.height` | `Dimensions.get("screen").height` | | `context.screen_density` | `window.devicePixelRatio` | `Dimensions.get("screen").scale` | | `context.viewport_width` | `window.innerWidth` | Not set | | `context.viewport_height` | `window.innerHeight` | Not set | | `context.os_name` | Not set | `iOS` or `Android` | | `context.os_version` | Not set | OS version string | | `context.device_model` | Not set | Device model (e.g., `iPhone 14 Pro`) | | `context.device_manufacturer` | Not set | Device manufacturer (e.g., `Apple`) | | `context.device_name` | Not set | Device name | | `context.device_type` | Not set | `mobile` or `tablet` | | `context.app_name` | Not set | From native config or options | | `context.app_version` | Not set | From native config or options | | `context.app_build` | Not set | From native config or options | | `context.app_bundle_id` | Not set | From native config or options | | `context.network_wifi` | Not set | `true` if connected via WiFi | | `context.network_cellular` | Not set | `true` if connected via cellular | | `context.network_carrier` | Not set | Cellular carrier name (when on cellular) | | `channel` | `"web"` | `"mobile"` | ## Sample Payload (Web) ```json theme={null} { "type": "page", "channel": "web", "context": { "user_agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/132.0.0.0 Safari/537.36", "locale": "en-US", "timezone": "Asia/Saigon", "location": "ID", "referrer": "https://chatgpt.com/", "utm_source": "chatgpt.com", "utm_medium": "", "utm_campaign": "", "utm_term": "", "utm_content": "", "page_url": "https://formo.so/faucets?utm_source=chatgpt.com", "page_title": "Free testnet faucets", "library_name": "Formo Web SDK", "library_version": "1.30.1", "browser": "chrome", "screen_width": 1920, "screen_height": 1080, "screen_density": 1, "viewport_width": 1920, "viewport_height": 969 }, "properties": { "url": "https://formo.so/faucets?utm_source=chatgpt.com", "path": "/faucets", "hash": "", "query": "utm_source=chatgpt.com", "name": "Faucets", "category": "Docs", "title": "Free testnet faucets" } } ``` ## Sample Payload (Mobile) Screen events from the [mobile SDK](/sdks/mobile) are sent as `page` events with `channel: "mobile"`: ```json theme={null} { "type": "page", "channel": "mobile", "version": "0", "session_id": "117b982a451dc22edea6413b8e20958216c0a5b3baaa1d90699c42dbf4e74e33", "anonymous_id": "c2bc0ebe-d852-49d1-9efd-e45744850ae0", "context": { "library_name": "Formo React Native SDK", "library_version": "1.0.0", "page_title": "Wallet", "page_url": "app://Wallet", "locale": "en-US", "timezone": "America/New_York", "location": "US", "os_name": "iOS", "os_version": "17.0", "device_model": "iPhone 14 Pro", "device_manufacturer": "Apple", "device_name": "Yos's iPhone", "device_type": "mobile", "app_name": "MyDeFiApp", "app_version": "2.1.0", "app_build": "42", "app_bundle_id": "com.example.mydefiapp", "network_wifi": true, "network_cellular": false, "screen_width": 393, "screen_height": 852, "screen_density": 3 }, "properties": { "name": "Wallet", "category": "Main" } } ```
