Reference

The client ID is a unique value generated by the coveo.analytics.js library that identifies a browser client on a Coveo-powered search page. It replaces an earlier value, the visitor ID, which is now deprecated.

The client ID is used as a proxy for an anonymous user, where a user ID isn’t available or isn’t supplied by the user. The combination of a client ID and a user ID helps Coveo track the number of unique visitors to your site. The client ID doesn’t directly identify a human user, but rather, the user’s browser, and multiple users may use that browser.

By default, the client ID is supplied to Coveo Usage Analytics (Coveo UA) and is kept in a first-party cookie as well as the local storage of the browser. See Local storage and cookies for details.

Note

In the local storage, you may still see the visitorID value instead of the clientID.

Advantages of using the client ID

While the client ID bears some similarities to the visitor ID, such as their longevity as well as their usefulness for gathering UA events, the client ID is preferred for several reasons.

For instance, it doesn’t rely on third-party cookies, which is an advantage since more and more browsers are blocking them.

Another reason to use the client ID is because it’s generated client-side, which gives front-end control of the ID generation. This resolves race condition issues experienced with the visitor ID. These issues occur when there are multiple analytics scripts since the visitor ID is generated by Coveo UA. Furthermore, multiple visitor IDs can refer to the same anonymous user; while it’s possible to match them, it’s a time-consuming process.

Notes

When both the client ID and the visitor ID are present, Coveo UA selects the client ID to resolve the visit associated with an event. Furthermore, when the client ID is present, Coveo UA doesn’t return a cookie containing the visitor ID value.
When sending an event, if there’s no ID provided, Coveo UA generates a visitor ID. The generated ID is returned in the response (see What if a client ID isn’t sent?).

Does my implementation pass the client ID?

To ensure that the client ID is being passed, it’s essential that the version of the Coveo JavaScript Search Framework used by your Coveo implementation is either the January 2021 version or a newer one. This is because as of January 2021, we implemented a mechanism for clients to send the client ID through the UA Write API to track user visits.

Note

If you aren’t using the Coveo UA library, you can still send the client ID by adding it to the payload on the call to the UA Write API.

We recommend that you first verify which version of the JavaScript Search Framework you’re currently using. You can identify the version from a search interface or the distribution files.

If you’re using a version older than the January 2021 version, you must then upgrade to a newer one. We recommend upgrading to the latest version.
If you’re using the January 2021 version (or newer), then you don’t need to do anything further except test the client ID to ensure that it’s functioning properly.

Note

All Coveo Headless and Atomic integrations use the correct version of the library, therefore the client ID is sent.

The following table lists the applicable version upgrades for different Coveo integrations:

Integration Upgrade

Integration	Upgrade
Coveo for Salesforce	Upgrade to 4.13 (or higher).
Coveo for Sitecore	If you track view events, you have two options: Upgrade to 5.0.943.3 and manually upgrade the `coveoua.js` file to v2. Upgrade to 5.0.1227.1 (or higher)
If you don’t track view events, upgrade to 5.0.943.3 (or higher).
Coveo for ServiceNow	Upgrade to 21.2.51 (or higher).
Coveo for Zendesk	Upgrade all search pages to 2.10083 (or higher).
Custom web (with `coveoua.js`) or React Native (with `react-native.es.js`)	Upgrade `coveoua.js` to the February 2020 version 2.0.0 (or higher).

Coveo for Salesforce

Upgrade to 4.13 (or higher).

Coveo for Sitecore

If you track view events, you have two options:

Upgrade to 5.0.943.3 and manually upgrade the coveoua.js file to v2.
Upgrade to 5.0.1227.1 (or higher)

If you don’t track view events, upgrade to 5.0.943.3 (or higher).

Coveo for ServiceNow

Upgrade to 21.2.51 (or higher).

Coveo for Zendesk

Upgrade all search pages to 2.10083 (or higher).

Custom web (with coveoua.js) or React Native (with react-native.es.js)

Upgrade coveoua.js to the February 2020 version 2.0.0 (or higher).

Note

Although you can upgrade to the January 2021 version, we recommend upgrading to the latest version available to ensure optimal performance.

If you have a custom integration, in addition to using a newer JSUI version, you must also ensure that the entirety of your integration is up to date. For example, if you’re using a combination that includes the Collect endpoint, ensure that the client ID is being sent to both the Coveo UA and the Collect endpoints. Also ensure that you’ve removed the visitor ID tracking mechanism. Otherwise, visits will consequently be split in two and this will affect reporting accuracy.

Test the client ID

There are several ways to verify that your Coveo implementation is passing the client ID:

You can access the Visit Browser.
You can create a custom dashboard.
You can use your browser’s developer tools.

Visit Browser

You can use the Visit Browser (platform-ca | platform-eu | platform-au) in the Coveo Administration Console by sorting through events. For example:

Custom dashboard

You can create a Client ID verification dashboard.

On the Reports (platform-ca | platform-eu | platform-au) page, add a blank dashboard.
In the upper-right corner of the window, click , and then select Paste JSON configuration.
In the Import a Report Configuration panel that appears, paste this JSON configuration, and then click Import and save.
Adjust the date range to specify the date your upgrade was completed.
Inspect the report to ensure that the All events and Events sending a Client ID cards are identical, with the same events and event counts, and that the Events leveraging a third-party cookie card is empty.

Developer tools

Use your browser’s developer tools to view the client ID.

Open a Coveo-powered search page.
Open your web browser’s developer tools.
Note

The examples in this article use the Google Chrome developer tools. For browser-specific information, see:

Google Chrome

Mozilla Firefox

Safari
Select the Network tab.
On the search page, perform a query to trigger an event.
Back in the developer tools window, under the Name column, click the latest call to Coveo UA.
Select the Payload tab. Then, under the Request Payload section, expand the actionCause to view the client ID. For example:

Reference

To test whether your search interface sends your client ID, paste this code into the Import a Report Configuration panel when creating the Client ID verification dashboard.
