Hooks/callbacks

What are UXWizz callbacks?

The UXWizz callbacks or hooks are a way to tap into the client-side UXWizz tracking functionality and listen to specific events. This is useful, for example, if you want to read or forward some UXWizz tracking data to another service.

Available callbacks

UST.onLoaded()
- Called as soon as the ust.min.js finishes loading.
UST.onTrackingStarted() : false | undefined
- Called when all tracking checks passed, meaning that a new session will be created.
- This is called before the session was created.
- If you want to stop creating this session, return false from this function.
UST.onSessionCreated(clientID: number)
- Called when the UXWizz server create a new session for this client
- clientID: The integer number ID of the session.
- This is called only once per visit for each visitor.
UST.onPageViewCreated(clientID: number, clientPageID: number)
- Called when a new page has loaded and the server responded with the pageview ID.
- clientID: The integer ID of the session.
- clientPageID: The integer ID of the pageview.
- This callback is also called once immediately after onSessionCreated (first pageview).
UST.onDataSent(data: string[])
- Called whenever tracking data (session recording/heatmap data) is sent to the server.
- data: An array of data strings sent to the server. Each data string is in the format c=XXX where c is the data type and XXX is the data value. The data type can be:
  - m - Heatmap movements
    Data value is a Positions string
  - c - Heatmap clicks
    Data value is a Positions string
  - p - Partial recording data
    Data value is a Recording string
  - r - Full recording data (sent when pageview has finished)
    Data value is a Recording string
  - x - Recording type
    Data is an integer
  - w - We have a complete recording
    Data is 1 (or not set)
  - s - Skip updating lastActivity
    Useful for when we want to update data for a user, without automatically refreshing/increasing the user's session duration.
    Data is 1 (or not set)
  - i - clientPageID
    Data value is a number
UST.onTagAdded(tag: string)
- Called when UST.addTag() was called and the server responded.
- tag: The string that has just been added as a tag to the current user.
UST.onEventAdded(eventData: Event)
- Added in version 3.5.0
- Called when UST.addEvent() was called and the server responded.
- eventData: The original eventData passed, also containing clientID and clientPageID
UST.onGDPRAccepted()
- Called when the user accepted the UXWizz tracking consent pop-up.
UST.onGDPRDeclined()
- Called when the user declined the UXWizz tracking consent pop-up.

Usage example

Make sure write the callbacks declarations after the tracking file is included.

Example: Multiple UXWizz callbacks

// <head>
// After ust.min.js include snippet
// ...
// <script>

// Example: User will be recorded
UST.onTrackingStarted = function() {
    console.log('Creating session...!');
}
   
// Example: New session has been created with an unique clientID
UST.onSessionCreated = function(clientID) {
     console.log('New session created for client', clientID);
}

// Example: whenever a tag is added, add the same tag + current pageID
UST.onTagAdded = function(tag) {
    if (tag === 'AddToCart' || tag === 'Converted') {
         UST.addTag(tag + ';' + sessionStorage.clientPageID);
    }
} 

// <script>
// </head>

Example: Dynamically disable tracking the current visitor

// Example: Permanently disable tracking a visitor once they reached checkout
UST.onTrackingStarted = function() {
    if (window.location.path === '/checkout-complete') {
        // Starting with the next page-load disable tracking this user (permanently)
        UST.disableRecord();
        
        // Return `false` to stop tracking this first pageview too
        return false;
    }
}

Example: Track the current user but disable session recording

UST.onTrackingStarted = function() {
     // Disable session recording for specific IPs
     // Note: `ust_myIP` is globally populated ONLY if you have set 
     // some excluded IPs in the tracking settings
     if (['123.456.12.13', '127.0.0.1'].indexOf(ust_myIP) !== -1) {
         UST.settings.enableSessionRecordings =  false; // Disable sending rec data
         UST.fullRec = false; // Disable attaching the full recorder
         UST.nativeSessionRecording = false; // Disable attaching the native recorder
     }
     
     console.log('Creating pageview...!');
}

After the session has been created (onSessionCreated), you can always read the current userTrack clientID and clientPageID from sessionStorage:

sessionStorage.getItem('clientPageID')

sessionStorage.getItem('clientID')

sessionStorage.getItem('token') token - Another unique identifier per session (similar to clientID). This is useful as it's not incremental.

Notes

Positions string (compressed format):

"X1^Y1^count1~X2^Y2^count2"
// For example:
"303^490^1~441^570^1~439^642^1"

Recording string (compressed format)

// This is more complex, looking at the data send or in the ust_records
// Should give you some idea of the format
// Some event names and their shorthand character:
enum PlaybackEventType {
    CLICK = 'c',
    SCROLL = 's',
    MOVEMENT = 'm',
    INACTIVITY = 'i',
    BLUR_INPUT = 'b',
    TEXT_SELECTION = 'a',
    WINDOW_RESIZE = 'r',
}

// For example
"a`body(2)(1)(5)(1)(2)(4)(2)(4)%201%23T%23^body(2)(1)(5)(1)(2)(4)(2)(4)%201%23T%23^8^9~i`80"
"m`966^1016~i`8~s`0^806~s`0^998~m`954^1415~s`0^1000~m`962^1416"
