Use the Relay library

Coveo Relay is a compact client library designed for transmitting analytics events to Coveo’s Event service. It plays a pivotal role in Coveo Usage Analytics (Coveo UA), enabling the tracking of user interactions with your search interfaces. This tracking is crucial for powering reports and training Coveo Machine Learning (Coveo ML) models.

Under the hood, Relay sends events to Coveo’s Event API. To perform event validation, refer to the Coveo Explorer extension. Relay integrates with this extension for seamless event validation.

Using Relay for sending events to the Event API is highly recommended over direct interactions with the API, as the library handles many complexities of event transmission.

The initialization options offered by Relay let you authenticate requests and direct them to the correct endpoint. Once set up, Relay actively manages various aspects of generic event logging, including enriching events with browser-specific details like user agent and local time. It also maintains a unique client identifier for each browser and device combination.

Relay allows you to focus on core implementation aspects, ensuring events are triggered by the right user interactions and carry the correct payload. Compared to the older coveoua library, Relay is more lightweight and offers integration with Explorer, providing real-time event validation and enhancing the overall Event Protocol experience.
