Overview

Schema is a framework to maintain your data, organize, and structure it. It enforces rules to maintain data integrity so that you can avoid data quality issues later. Schema standardizes your data before you even begin using it. Since bad data leads to a high cost in effort and money, you can save a lot of manual effort on tracking your data in the long run.

To preserve data sanity, the schema table stores event and user properties in a pre-defined order. It ensures better output because it enforces standardization of the incoming data and avoids duplication or corruption of data. Better input leads to a better outcome in your campaigns and journeys. It also provides more accurate insights into your data analytics.

Events

You can see your events under Settings > Schema Events. On this page, you can view all the events you are working with, along with editing or discarding to searching and filtering them.

The Events schema has four parts:

• Custom events
• System events
• Conversion event
• Qualifying event

Custom Events

Custom events are events that you can define, edit, remove, and so on. These are your app events that you can fully control.

1. Navigate to Settings > Schema > Events.
2. Click the Custom events tab.

If you have already defined your events, they are all present on this tab.

Add Event

You can add an event from the Custom events tab.

1. Navigate to Settings > Schema Events > Custom events.
2. Click the +Event button to add an event.
3. Add the event name. This name must be unique in the schema.

For more information, refer to Event Property.

Edit Event

The name cannot be changed after the event is published.

1. Click the edit icon on the event row.
2. Edit the event name.
3. Click the checkmark.

Set Data Retention Policy

The data retention policy (DRP) retains an event for the specified time before discarding it automatically. Your subscription plan will decide the default DRP limit.

1. Navigate to Settings > Schema > Events.
2. From the System Events tab, click the ellipsis on the event row and click Set DRP.
3. Select Custom, then enter your specific time limit.

📘

CleverTap Basic Plan Limit

The default DRP for CleverTap Basic Plan users is one year, which cannot be changed.

4. Click Save.

Remove Event

You must be careful before removing an event. If you ever need to remove an event from the schema, remove it from the event row on the Events page. You can only remove an inactive event from your schema; however, the effects are minimal because the event is not active. This action does not drop another event coming in with the same name.

1. Click the ellipsis menu on the event row.
2. Click Remove.

After an event is removed:

• The entire event row is removed from the schema.
• If an event comes in with the same name, it is considered an undefined event.

Discard Event

You can discard an active event from the schema. You can still see the event row in the schema; however, it will be marked as discarded.

❗️

Caution When Discarding an Event

You can only discard an active event. Exercise extreme caution when discarding an event because this action cannot be undone. This action has an impact on your schema because it purges all data for the discarded event. It also drops any future incoming event with the same name.

1. Click the ellipsis menu on the event row.
2. Click Discard.

Define Event

The events that are passed to CleverTap but not defined are marked as undefined events. You can define these events from the event row. Defining an event marks it as a recognized event in the schema, and therefore, when the event is received, this will not cause any error.

1. Click the ellipsis menu on the event row.
2. Select Define Event, and a new window displays.
3. Click Define & Save.

Publish Schema/Events

To publish the events, perform the following:

1. Check that you have all the required events.
2. Click the Publish Events button.

📘

Effect of Changing the Data Type of an Event or User Property

• If you change the user or event property's data type, then all the incoming data will be validated as per the schema definition once you publish the changes.
• The values already present in the old data type will not change in the new data type.
• For the users who already have the value of the user/event property in the old data type, you will have to again pass the user/event property with the value that will have a new data type.

Add Event Property

To add an event property:

1. Click the number of properties shown in the Custom events tab
2. Click +Property, then click Add new.
   You can also add an event property from the catalog by clicking Add from catalog. For more information, refer to Add Columns from a Catalog.

Remove Event Property

You can remove an unpublished event property.

After an event property is removed:

• The entire event property row is removed from the schema.

2. Click Discard, and a new window displays.
3. Click Discard again.

System Events

System events are tracked automatically. CleverTap offers the capability to configure system events, enabling businesses to monitor and analyze user actions in their applications. However, some businesses may not have an immediate need for certain system events, resulting in potentially avoidable expenses. CleverTap allows businesses to configure those unused system events, providing a seamless process to address this issue.

Configure System Events

To configure the tracking of system events:

1. Navigate to Settings > Schema > Events from the CleverTap dashboard.
2. Select the event that you want to configure from the System events tab.
3. Click the icon and select Enable/Disable from the list.

Currently, you can enable or disable tracking for the following events from the CleverTap dashboard:

Push Impression

The Push Impression event is tracked when a push notification sent from CleverTap is delivered to a user’s device. After the toggle for Push Impressions is turned on, the CleverTap SDK starts recording an event whenever a push notification sent via CleverTap is delivered to the user’s device.

The Push Impression event has its own event properties and the users can configure these non-required event properties to optimize the cost.

To do so:

1. Navigate to Settings > Schema > Events from the CleverTap dashboard.
2. Select the Push Impressions event from the System events tab.
3. Click the icon and select Setup push impressions from the list.
4. Turn ON the Mobile Push toggle and click Save. The Push impressions tracking enables message displays on the screen.

Disable Event Property Tracking

The users can disable the tracking of some of the Push Impression event properties from the CleverTap dashboard. However, there are a few Push Impression event properties for which you do not have the option to disable the tracking. These are listed as follows:

Property	Property Description	Configurable
wzrk_push_amp	Push amplification flag	No
wzrk_pn	The flag to check if the Push is from CleverTap or not.	No
CT Source	CleverTap Source	No
wzrk_id	The ID of the campaign.	No
wzrk_pid	Unique push notification ID	No
wzrk_pivot	Variant	No
wzrk_acct_id	CleverTap Account ID	No
CT App Version	CleverTap App Version	No
wzrk_dt	Delivery type	No
wzrk_acts	CTA button	No
wzrk_pn_h	RenderMax health state	No

To disable the tracking of Push Impression event properties:

1. From the System events tab, click the Properties hyperlink. The Push Impressions properties list opens.

2. Select the configurable property, click the icon, and select Disable Property from the list. The Enable property tracking popup opens.

3. Click Disable to confirm your action. The Property tracking successfully disabled message displays on the screen. The status of the event property changes to Active. Once disabled, if you want to enable the tracking later, you can do so by clicking the icon and selecting Enable Property from the list.

📘

Key Points to Remember

The following are some of the points to consider when configuring the Push Impressions event:

• The event property tracking feature is not available for required properties.
• The Status is always Active for mandatory properties.
• The tracking of configurable properties is enabled by default for new (new users of CleverTap dashboard) or returning users (existing users who turned off push impression feature) of Push Impression feature.
• For existing users, the tracking of event properties remains as is, however, they have the additional capability to enable/disable tracking for the same.

Web Session Started

This is a web entry event similar to the App launched event. This event refers to the event triggered when a user starts a session or engages with your website. This event will be recorded in two cases:

• When a user opens a webpage.
• When a user reloads the browser after 20 minutes of inactivity.

📘

Default Behavior

This event is disabled by default for all customers and can be configured by the customers. When enabled, it captures the unique visitors to the website in a particular session.

UTM Visited

The UTM Visited event is tracked when a user clicks on a link from a marketing campaign that has a UTM parameter defined on it. This event is also tracked when a CleverTap-integrated attribution platform, such as AppsFlyer or Branch, sends this information to CleverTap. This event is recorded for your marketing campaigns from external sources, such as Google Ads or Facebook.

📘

Deault Behavior

The UTM Visited tracking is ON for new customers by default. For existing customers, the tracking of UTM Visited remains as is. However, they have the capability to enable or disable the same.

📘

Configuring Other System Events

For the remaining system events, you can only change the DRP.

Conversion Event

The conversion event helps track conversion.

To set a conversion event:

1. Navigate to Settings > Schema > Events.
2. Click the Conversion event tab.

To track revenue, set the user conversion event and revenue property. This property must be a numeric value.

Qualifying Event

To set a qualifying event:

1. Navigate to Settings > Schema > Events.
2. Click the Qualifying event tab.

This event qualifies users as active if they have performed the event at least once in the defined time.

Currently, the active % tab uses the qualifying event on the Trends page.
