Features

• Multi-Destination Data Routing - Implements a unified interface to route collected customer data to multiple third-party analytics destinations simultaneously.
• Multi-Destination Event Routing - Routes a single stream of event data to multiple external analytics destinations through a unified interface.
• Page View Tracking - Records page visits and allows the attachment of custom categories and properties to describe the view.
• Behavioral Data Collection - Collects behavioral user interaction events from digital interfaces for distribution to analytics tools.
• Customer Data Management - Identifies unique users and associates them with specific traits and historical identities across sessions.
• Customer Data Platforms - Functions as a customer data platform for gathering user signals and creating a unified behavioral view.
• Third-Party Data Connectors - Provides connectors to import user and event data from cloud applications for distribution to analytics tools.
• User Identification - Links users and their actions to a unique ID and a set of descriptive traits.
• Event Tracking APIs - Provides a tracking API that enables analytics event transmission from any environment capable of making HTTP requests.
• Event Middleware Systems - Uses a sequence of middleware functions to intercept and modify event data before dispatching it to destinations.
• Stream Event Interception - Employs middleware to intercept, modify, or drop event payloads before they reach their final destinations.
• Behavioral Event Collectors - Provides a browser-based tool for recording page views, form submissions, and link clicks.
• User Interaction Event Logging - Logs specific user actions and includes optional properties to provide context for behavioral analysis.
• User Interaction Recording - Logs specific user actions like form submissions and link clicks for behavioral analytics.
• Analytics Integration Libraries - Provides a JavaScript library for collecting user behavior and distributing event data to multiple analytics destinations.
• Cross-Subdomain Identity Tracking - Tracks unique users across subdomains by storing anonymous identifiers on the top-level domain.
• Web Analytics Integrations - Integrates web applications with analytics services to track user behavior and page views.
• Reverse ETL - Synchronizes processed data from cloud warehouses back into operational marketing and analytics tools.
• Marketing Analytics - Tracks marketing campaign effectiveness by extracting UTM parameters from URLs and recording page views.
• Link Interaction Tracking - Logs clicks on hyperlinks and delays page navigation to ensure analytics data is transmitted.
• Integration Filtering - Provides the ability to enable or disable specific third-party tool integrations for individual event calls.
• Fetch Keepalive Deliveries - Utilizes the browser fetch keepalive flag to ensure analytics data delivery during page unloads and redirects.
• Cross-Subdomain Session Sharing - Maintains consistent user identity across subdomains by storing anonymous IDs on the top-level domain.
• Identity Aliasing - Combines separate user identities into a single profile to maintain a consistent behavioral history.
• Request Batching - Groups multiple individual event calls into a single HTTP request to reduce network overhead.
• Client-Side Persistence - Implements a local storage-based retry queue with exponential backoff to prevent data loss during network outages.
• Submission Tracking - Binds tracking calls to form submissions and delays redirection until the event is successfully delivered.
• Async Request Completion - Uses the browser keepalive flag to guarantee analytics data transmission completes during hard page redirects.
• Persistent Retry Queues - Persists failed network requests in the browser's local storage and attempts redelivery with exponential backoff.
• UTM Parameter Parsing - Automatically reads marketing campaign data from URL query strings and attaches it to event payloads.
• HTTP Middleware Pipelines - Implements a middleware pipeline to modify event payloads and add custom headers before API transmission.
