Use Qubit Explorer to validate your setup

In this article...

We'll show you how to use the Qubit Explorer to validate your setup.

Getting started

The Qubit Explorer, provides a real-time insight into the accuracy, completeness, and overall quality of the data being triggered on a page and is our recommended tool for taking your first steps in validating your QProtocol setup.

TIP: Qubit Explorer can also be used to preview your experiences and test your segments.

For developers

The tool will be of particular interest to those developers looking for a window into what events are being emitted on a page and the results of the checks we perform on those events to ensure they are emitted according to our event schemas.

The Explorer provides a clear indication of the causes of any errors and pinpoints the precise location in your QProtocol implementation for the page:


For marketers and strategists

For marketers and strategists, the tool provides an effective means of verifying what data is being generated on a page and that the data emitted is aligned with the defined business goals for that page.

TIP: If your focus is on a particular feature, rather than the page itself, we recommend using the option Enable events per session. Enabling this option will aggregate the events in the Explorer for a session. This option is explained in detail in Enabling events for a session.

INFO: It is worth pointing out that the Explorer only reports those errors that relate to events triggered by your navigation around a page and through your site. For a more in-depth view of errors generated by actual visitor activity on your page and over different time periods, we recommended using the Validation Dashboard.

Starting Qubit Explorer

To start Qubit Explorer, select Experiences from the side menu and select Launch Explorer:

launch the explorer

Alternatively, open an experience from one of your lists and select grey eye in the top-right hand corner of the page. Once your site has loaded, you will see an on-page prompt:


Select this to open the Explorer and then select Events:


TIP: You can also start the explorer directly on your site by appending ?qubit_explorer to your site's URL, e.g.

WARNING: Users that have added third-party privacy or security-related browser extensions, such as Ghostery, may experience difficulties in opening the explorer. See Using Qubit Explorer with privacy and security-related browser extensions for resolution steps.

Viewing events

So, we've opened the Explorer and we can now see a list of events triggered on the page. For each event, we report the event name, a count showing how many times the event was emitted on the page, and a status:

event status

  • Rejected - We reject any event emitted before the first view event on a page, for example, ecView, egView, trView. Rejected events are not collected by Qubit
  • Received with errors - This means that the event has been checked and validated by Qubit's systems, but has returned errors. Depending on the type of error, the event will be rejected as an invalid event. The data in an invalid event is collected by Qubit but it is not processed and is therefore not available for use in the Qubit platform
  • Received - This means that the event has been checked and validated by Qubit's systems and has not returned errors. It is a valid event. The data generated by the event is collected and processed by Qubit and will be available for use in the Qubit platform

A focus on event validity

Why is it important that QP events are valid? Even though valid and invalid events are collected and stored in BigQuery, only valid events are processed. Invalid events by comparison are not processed and the data within the event is not available for use in the Qubit platform. Invalid events therefore represent lost data.

Lost data has downstream consequences that can potentially affect segment metrics, reporting against experience goals and the likely impact of an experience, and your wider ability to influence your customers with personalized experiences.

Troubleshooting event validity is therefore a crucial part of setting up Qubit. Beyond using the Validation Dashboard to help you in this task, we highly recommend paying particular attention to our setup guides and the field-level requirements for each event.

Troubleshooting rejected events and events received with errors

Rejected events

Any event emitted before the first view event on a page is rejected. Therefore, the first place to start when resolving rejected events is to make sure that the first event emitted on a page is a view event, for example ecView, egView, trView.

To view the rejection reason, select the event from the list shown:


Events received with errors

To help you resolve events received with errors, we always indicate the root cause. You can view this by selecting the event and then placing your cursor over the highlighted line number. In the following example, we see that the root cause is that the value for currency field is missing:

event received with errors

Where the line number is highlighted in orange, the error is non-critical and will not result in the event being validated as invalid:

orange highlighting

Where the line number is highlighted in red, the error is critical and will result in the event being validated as invalid:

red highlighting

Refer to the following table for an explanation of issue types:

Issue type



Data quality

Depends on the event, but can include:

-event field containing an invalid value

-event contains required and valid data points but contextual issues have been found that will affect the quality of the generated data

product.productId and product.sku are identical

Corresponding ecBasketSummary event is missing

Corresponding ecBasketItem event is missing

Schema validation

Invalid field type

Invalid field type for entrySuccess field

Expected type is boolean but was string

Missing information

The event contains the required data points but 1 or more of those data points is missing value that is required by one of more of Qubit’s products

product.description is null

basket.quantity is null


The event contains the required data points and valid values but has been customized in a non-standard implementation

Custom properties extended beyond the expected schema

Minimizing the Explorer window

To give you a better view of your site, you can minimize the Explorer window by selecting minimize

Filtering events

Particularly useful those users interested in validating their QProtocol implementation against a Qubit product or implementation level, filters enable you to concentrate on those events that really matter to you.

For example, you might wish to validate against the events required for a particular product such as Recommendations or Social proof. Alternatively, you might wish to validate against an implementation level, such as Best practice.

By default, the Explorer will show all events emitted on the page. To change this, make a selection from the combo box provided:


The filters available to you will vary according to vertical and will be based on your Qubit setup. When you select a filter, the events panel is updated and will show the QProtocol events emitted on the page that are associated with that filter.

Refer to the following table, which shows the filters and events included in each filter for the eCommerce vertical as an example:



Events included


The absolute minimum events in a QP setup

View event and transaction event, ecView ecBasketTransactionSummary


The events required to set up Qubit Aura

ecView, ecProduct, ecBasketItemTransaction, ecBasketTransactionSummary

Best practice

Our recommended events by vertical, for example, see:
Setup for eCommerce
Setup for eGaming

ecBasketSummary, ecView, ecUser, ecBasketItemTransaction, ecBasketItem, ecProduct, ecBasketTransactionSummary, ecBasketItemAction


Our recommended events for the Recommendations Programmatic Experience

ecView, ecProduct, ecBasketTransactionSummary, ecBasketItemAction

Abandonment recovery

Our recommended events for the Abandonment recovery Programmatic Experience

ecView, ecUser, ecProduct, ecBasketTransactionSummary

Social proof

Our recommended events for the Social proof Programmatic Experience

ecView, ecUser, ecProduct, ecBasketTransactionSummary, ecBasketItemTransaction

Expected events

To help you analyze and resolve any gaps in your QProtocol implementation, when you select a product, we will also show the events that are expected for that product.

These are events represent the required data points for the product to function correctly and for data completeness, as reported in our setup guides:

Clearing the events in the Explorer

To clear the events from the Explorer, select Reset. You can now refresh the page or continue with your navigation to re-populate the Explorer with events.

Enabling events for a session

By default, when you navigate to a new page or refresh a page, the events emitted on the previous view are cleared. This gives you a clean view of the events emitted on each page. Because some experiences and features span multiple pages, we have provided the option to view the events emitted on each page in your session.

To enable this option, select grey cog and Enable events per session.

Enabling console logs

For more advanced event debugging, you can enable console logs to write event errors to your browser's console.

To do this, select grey cog and Enable console logs. Let's take a look at an example:

console error

In the above example, we write the 3 errors reported in the Explorer to the console. We can then inspect each of these errors. Let's take a look at the ecBasketSummary event error:

ecBasketSummary error

Here we can see in even more detail the root cause of the error, including the QProtocol path:

{issueId: "basketQuantityAbsent", description: "basket.quantity is null", type: "Missing information", qpPath: "basket.quantity"}

Using Qubit Explorer with Ghostery

Some third-party privacy or security-related browser extensions, such as Ghostery, may prevent Qubit Explorer from loading correctly in the browser.

If you have enabled the option Enhanced Anti-Tracking, Ghostery will trigger a re-authentication with Qubit and will prevent you from logging in. You can avoid this by disabling this option in the Simple View:
