API Reference

Complete reference for all SDK methods.

Initialization

`priv.init(config)`

Initialize the SDK with your configuration. Must be called before any other methods.

import { priv } from '@priv/sdk';

priv.init({
  apiKey: 'pk_your_api_key',
  endpoint: 'https://api.priv.io/v1',
  debug: true,
});

Parameters:

Name	Type	Required	Description
`config.apiKey`	`string`	Yes	Your PRIV API key
`config.endpoint`	`string`	Yes	Analytics endpoint URL
`config.debug`	`boolean`	No	Enable debug logging
`config.flushInterval`	`number`	No	Flush interval in ms (default: 5000)
`config.flushAt`	`number`	No	Events before auto-flush (default: 10)
`config.autoTrackPageViews`	`boolean`	No	Auto-track pages (default: true)
`config.autoTrackClicks`	`boolean`	No	Auto-track clicks (default: false)
`config.autoTrackScroll`	`boolean`	No	Auto-track scroll (default: false)

Returns: void

See Configuration for full details.

Tracking Methods

`priv.track(event, properties?)`

Track a custom event with optional properties.

// Basic tracking
priv.track('button_click');

// With properties
priv.track('purchase', {
  product_id: 'prod_123',
  price: 99.99,
  currency: 'USD',
  quantity: 1,
});

// Track form submission
priv.track('form_submitted', {
  form_id: 'signup',
  fields_filled: 5,
  time_spent: 30,
});

Parameters:

Name	Type	Required	Description
`event`	`string`	Yes	Event name (e.g., 'button_click')
`properties`	`EventProperties`	No	Additional event data

Properties Type:

type EventProperties = Record<string, string | number | boolean | null | undefined>;

Returns: void

Best Practices:

Use snake_case for event names
Keep property values simple (strings, numbers, booleans)
Use consistent naming across your app

`priv.page(name?, properties?)`

Track a page view with optional name and properties.

// Auto-capture page details
priv.page();

// Named page
priv.page('Dashboard');

// With properties
priv.page('Product Page', {
  product_id: 'prod_123',
  category: 'electronics',
});

Parameters:

Name	Type	Required	Description
`name`	`string`	No	Page name (defaults to document title)
`properties`	`EventProperties`	No	Additional page data

Auto-captured Properties:

The SDK automatically captures:

url - Full page URL
path - URL pathname
referrer - Document referrer
title - Document title

Returns: void

Identity Methods

`priv.identify(userId, traits?)`

Identify a user and associate them with their events.

// Basic identification
priv.identify('user_123');

// With traits
priv.identify('user_123', {
  email: 'user@example.com',
  name: 'John Doe',
  plan: 'pro',
  company: 'Acme Inc',
  created_at: '2024-01-15',
});

Parameters:

Name	Type	Required	Description
`userId`	`string`	Yes	Unique user identifier
`traits`	`UserTraits`	No	User attributes

Traits Type:

type UserTraits = Record<string, string | number | boolean | null | undefined>;

Returns: void

Important: Call identify() after login and before tracking events to ensure all events are associated with the user.

`priv.reset()`

Clear the current user identity. Call this on logout.

// On user logout
function handleLogout() {
  // Clear session
  authService.logout();

  // Reset analytics identity
  priv.reset();
}

Returns: void

After calling reset():

User ID is cleared
A new anonymous ID is generated
New session is started

`priv.setConsent(granted)`

Set the user's GDPR consent status. Tracking only occurs when consent is granted.

// After user accepts cookies
priv.setConsent(true);

// After user rejects tracking
priv.setConsent(false);

Parameters:

Name	Type	Required	Description
`granted`	`boolean`	Yes	Whether consent is granted

Returns: void

GDPR Compliance:

The SDK is designed for GDPR compliance:

Initialize the SDK (no tracking yet)
Show consent banner to user
Call setConsent(true) when user accepts
Tracking begins

// Initialize SDK (no tracking yet)
priv.init({ apiKey: 'pk_xxx', endpoint: '...' });

// Show your consent banner...

// When user accepts:
onConsentAccepted(() => {
  priv.setConsent(true);
  priv.track('consent_granted');
});

// When user rejects:
onConsentRejected(() => {
  priv.setConsent(false);
});

`priv.isTracking()`

Check if tracking is currently active.

if (priv.isTracking()) {
  console.log('User has consented, tracking is active');
} else {
  console.log('No consent or SDK not initialized');
}

Returns: boolean

Returns true if:

SDK is initialized
Consent has been granted via setConsent(true)

Utility Methods

`priv.getAnonId()`

Get the anonymous ID for the current user/device.

const anonymousId = priv.getAnonId();
console.log('Anonymous ID:', anonymousId);
// Output: "anon_a7b8c9d0e1f2..."

Returns: string

The anonymous ID:

Is generated on first SDK initialization
Persists across page loads (stored in localStorage)
Is included with all events
Allows event correlation before user identification

`priv.shutdown()`

Shutdown the SDK and flush any pending events.

// Before page unload or app close
priv.shutdown();

Returns: void

Use this:

Before page unload to ensure events are sent
When unmounting your app
For cleanup in single-page applications

// React example
useEffect(() => {
  priv.init({ ... });

  return () => {
    priv.shutdown();
  };
}, []);

TypeScript Types

import type {
  PrivConfig,
  EventProperties,
  UserTraits,
  TrackEvent,
  IdentifyEvent,
  PageEvent,
  PrivEvent,
  ConsentState,

  endpoint: string;
  debug?: boolean;
  flushInterval?: number;
  flushAt?: number;
  autoTrackPageViews?: boolean;
  autoTrackClicks?: boolean;
  autoTrackScroll?: boolean;
}

/** Event properties - flexible key-value pairs */
type EventProperties = Record<string, string | number | boolean | null | undefined>;

/** User traits for identification */
type UserTraits = Record<string, string | number | boolean | null | undefined>;

/** Track event payload */
interface TrackEvent {
  type: 'track';
  event: string;
  properties: EventProperties;
  timestamp: string;
  anonymousId: string;
  userId?: string;
  sessionId: string;
}

/** Identify event payload */
interface IdentifyEvent {
  type: 'identify';
  traits: UserTraits;
  timestamp: string;
  anonymousId: string;
  userId?: string;
  sessionId: string;
}

/** Page view event payload */
interface PageEvent {
  type: 'page';
  name: string;
  properties: EventProperties & {
    url: string;
    path: string;
    referrer: string;
    title: string;
  };
  timestamp: string;
  anonymousId: string;
  userId?: string;
  sessionId: string;
}

/** Consent status */
interface ConsentState {
  granted: boolean;
  timestamp: string;
}

Complete Example

import { priv } from '@priv/sdk';
import type { PrivConfig, EventProperties } from '@priv/sdk';

// 1. Configure and initialize
const config: PrivConfig = {
  apiKey: process.env.NEXT_PUBLIC_PRIV_KEY!,
  endpoint: 'https://api.priv.io/v1',
  debug: process.env.NODE_ENV === 'development',
  autoTrackPageViews: true,
};

priv.init(config);

// 2. Handle consent
function handleConsentDecision(accepted: boolean) {
  priv.setConsent(accepted);

  if (accepted) {
    priv.track('consent_accepted');
  }
}

// 3. Identify user on login
function handleLogin(user: { id: string; email: string; plan: string }) {
  priv.identify(user.id, {
    email: user.email,
    plan: user.plan,
  });

  priv.track('user_logged_in', {
    method: 'email',
  });
}

// 4. Track events throughout your app
function handlePurchase(product: { id: string; price: number }) {
  const properties: EventProperties = {
    product_id: product.id,
    price: product.price,
    currency: 'USD',
  };

  priv.track('purchase_completed', properties);
}

// 5. Handle logout
function handleLogout() {
  priv.track('user_logged_out');
  priv.reset();
}

// 6. Cleanup on app close
window.addEventListener('beforeunload', () => {
  priv.shutdown();
});
