[Opensend SDK](https://help.opensend.com/getting-started?hsLang=en#opensend-sdk) # Frequently Asked Questions ## Common questions and answers about the OIR SDK.   ### General Questions #### What is the OIR SDK? The OIR SDK is a lightweight JavaScript tracking SDK designed for modern browsers. It provides event tracking, user identification, and cross-tab synchronization. #### Which browsers are supported? - Chrome 80+ - Firefox 75+ - Safari 13+ - Edge 80+ #### How do I install the SDK? The SDK can be installed via CDN. See the [Installation Guide](https://help.opensend.com/opensend-sdk/installation-guide?hsLang=en) for details. #### Is the SDK GDPR/CCPA compliant? Yes, the SDK is designed with privacy in mind: - No PII collection by default - Configurable data collection levels - Secure cookie handling --- ### Configuration Questions #### What configuration is required? The minimum required configuration: - `oirid`: Your publisher ID (from your account manager) - `oirtyp`: Pixel type identifier #### Can I configure the SDK after initialization? Yes, use the `cfg()` method: ``` window._oirtrk.cfg({ oirid: 'YOUR_INTEGRATION_ID', oirtyp: 'YOUR_INTEGRATION_TYPE',}); ```   #### What is brandedLinkDomain? The `brandedLinkDomain` option enables first-party tracking using your own domain. See [Configuration Guide](https://help.opensend.com/opensend-sdk/configuration-guide?hsLang=en) for setup instructions. --- ### Event Tracking Questions #### How do I track events? Use the `push()` method: ``` _oirtrk.push([ 'event', { event: 'event_name', // event properties },]); ```   #### Can I queue events before the SDK loads? Yes, events are queued automatically: ``` window._oirtrk = window._oirtrk || [];_oirtrk.push(['event', { event: 'early_event' }]);// SDK loads later and processes queued events ```   #### How do I set global custom data? Use the `set` command: ``` _oirtrk.push(['set', 'sessionId', 'abc123']);// Or multiple values_oirtrk.push(['set', { sessionId: 'abc123', userId: 'user_456' }]); ```   #### What events should I track for e-commerce? See the [E-commerce Events](https://github.com/Intelligence-Labs/tagoir-sdk/blob/develop/docs/user-guides/ecommerce-events.md) guide for the complete list including: - `view_item_list`, `view_item`, `select_item` - `add_to_cart`, `remove_from_cart`, `view_cart` - `begin_checkout`, `add_shipping_info`, `add_payment_info` - `purchase`, `refund` --- ### User Identification Questions #### How are Anonymous IDs generated? Anonymous IDs are generated automatically when the SDK initializes. This browser-based identifier is used to track visitors across sessions and tabs. #### Can I set my own custom ID? Yes, use the global custom data feature to set custom identifiers for your own purposes: ``` _oirtrk.push(['set', 'customId', 'your-custom-id']);_oirtrk.push(['set', 'puid', '12345']); ```   See the [Global Custom Data Guide](https://help.opensend.com/opensend-sdk/global-custom-data?hsLang=en) for more details. #### When should I call identify? Call identify when: - User logs in - User signs up - User provides information during checkout - User updates their profile --- ### Cross-Tab Questions #### How does cross-tab sync work? The SDK automatically coordinates across browser tabs using localStorage. Only one tab performs critical operations, and results are shared. #### Do I need to configure cross-tab sync? No, it works automatically without configuration. #### What happens if localStorage is unavailable? The SDK falls back gracefully to single-tab mode. --- ### Performance Questions #### Does the SDK impact page load? No, the SDK is designed for minimal impact: - Loads asynchronously - Minimal initialization time - Non-blocking event tracking #### How many network requests does the SDK make? One request per event. Events are sent immediately using fetch with keepalive. --- ### Troubleshooting #### Events are not tracking Check: 1. SDK is initialized (`window._oirtrk.cfg()` called) 2. Required configuration set (`oirid` and `oirtyp`) 3. Browser console for errors 4. Network connectivity #### Anonymous ID is not persisting Check: 1. localStorage/cookies are enabled 2. Browser privacy settings 3. Domain configuration #### Cross-tab sync not working Check: 1. localStorage is available 2. Tabs are on the same domain 3. Browser supports required features #### SDK is not loading Check: 1. Script tag is correct 2. CDN is accessible 3. No ad blockers blocking --- ### Getting Help #### Where can I find more documentation? - [Installation Guide](https://help.opensend.com/opensend-sdk/installation-guide?hsLang=en) - [Configuration Guide](https://help.opensend.com/opensend-sdk/configuration-guide?hsLang=en) - [Quick Start Guide](https://help.opensend.com/opensend-sdk/quickstart-guide?hsLang=en) - [Troubleshooting Guide](https://help.opensend.com/opensend-sdk/troubleshooting-guide?hsLang=en) #### How do I report a bug?
