API Methods

Once initialized, the Matomo tracker returns an object with the following methods:

trackEvent(category, action, name?, value?)

Tracks a custom event.

Parameters:

• category (string): The category of the event
• action (string): The action of the event
• name (string, optional): The name of the event
• value (number, optional): The value of the event

Example:

// Track a button click
matomo.trackEvent('Navigation', 'Click', 'Header Logo');

// Track with a value
matomo.trackEvent('Purchase', 'Complete', 'Premium Plan', 99.99);

trackPageView(url?, props?)

Tracks a page view in a single-page application.

Parameters:

• url (string, optional): The URL of the page to track. Defaults to window.location.href
• props (object, optional): Additional properties for the page view
  • deleteCustomVariables (boolean): Whether to delete custom variables. Default: true
  • documentTitle (string): Custom document title. Default: document.title

Example:

// Track current page
matomo.trackPageView();

Example:

Example:

// Set custom dimension
matomo.push(['setCustomDimension', 1, 'Premium User']);

// Track site search
