### Best Practices: Naming Conventions (HEYO SDK)

Source: https://heyo.so/docs/advanced-api-usage/tags-and-custom-fields

This example demonstrates clear and descriptive naming conventions for tags and custom fields using the HEYO SDK. It shows preferred usage like 'trial-user' and 'subscription-plan', contrasting with abbreviations that reduce clarity.

```javascript
// ✅ Good
HEYO.addTag('trial-user');
HEYO.setField('subscription-plan', 'pro');

// ❌ Avoid abbreviations
HEYO.addTag('trl');
HEYO.setField('sub-pln', 'pro');
```

--------------------------------

### Real-World Example: SaaS Application

Source: https://heyo.so/docs/advanced-api-usage/tags-and-custom-fields

Tracks subscription and usage details for SaaS applications by setting custom fields and tags related to the user's plan, payment status, and trial information.

```javascript
// User subscription info
HEYO.setField('plan', user.subscription.plan); // "starter", "pro", "enterprise"
HEYO.setField('mrr', user.subscription.mrr);
HEYO.setField('trial-ends', user.subscription.trialEndsAt);
HEYO.setField('is-paying', user.subscription.isActive);

// Tags for quick filtering
HEYO.addTag(user.subscription.plan); // "starter", "pro", etc.
if (user.subscription.isActive) HEYO.addTag('paying-customer');
if (user.subscription.isTrial) HEYO.addTag('trial-user');
```

--------------------------------

### Real-World Example: E-Commerce Store

Source: https://heyo.so/docs/advanced-api-usage/tags-and-custom-fields

Tracks customer value and status by identifying the user and setting relevant tags and custom fields. This snippet illustrates a common use case for e-commerce businesses.

```javascript
// After user logs in
HEYO.identify({
    userId: user.id,
    email: user.email,
    name: user.name,
});

// Add relevant tags
HEYO.addTag('customer');
if (user.orders.length > 0) HEYO.addTag('has-purchased');
if (user.totalSpent > 1000) HEYO.addTag('high-value');

// Set custom fields
HEYO.setField('total-spent', user.totalSpent);
HEYO.setField('order-count', user.orders.length);
HEYO.setField('last-purchase', user.lastOrderDate);
HEYO.setField('is-vip', user.isVIP);
```

--------------------------------

### Best Practices: Keep It Simple (HEYO SDK)

Source: https://heyo.so/docs/advanced-api-usage/tags-and-custom-fields

This code illustrates the principle of keeping tag and field usage simple with the HEYO SDK. It shows the 'good' example of using essential information like 'paying-customer', 'plan', and 'mrr', while highlighting the 'too much' example of excessive, redundant tagging.

```javascript
// ✅ Good - essential info
HEYO.addTag('paying-customer');
HEYO.setField('plan', 'pro');
HEYO.setField('mrr', 99);

// ❌ Too much - overwhelming
HEYO.addTag('customer');
HEYO.addTag('paying');
HEYO.addTag('active');
HEYO.addTag('verified');
HEYO.addTag('engaged');
// ... 20 more tags
```

--------------------------------

### Add Heyo Script Tag to Website

Source: https://heyo.so/docs/getting-started/introduction

Integrates the Heyo live-chat widget into your website by adding a script tag before the closing </head> tag. This is the simplest way to get started.

```html
<script src="https://heyo.so/embed/script" defer async></script>

```

--------------------------------

### Best Practices: Using Tags for Categories (HEYO SDK)

Source: https://heyo.so/docs/advanced-api-usage/tags-and-custom-fields

This example illustrates the best practice of using tags for simple categorization with the HEYO SDK. It shows adding tags like 'premium', 'active', and 'verified' for clear segmentation, contrasting it with avoiding complex state information in tags.

```javascript
// ✅ Good - simple categories
HEYO.addTag('premium');
HEYO.addTag('active');
HEYO.addTag('verified');

// ❌ Avoid - complex state better in fields
HEYO.addTag('plan-premium-monthly-299'); // Use custom field instead
```

--------------------------------

### Get Current Agent Status and React

Source: https://heyo.so/docs/advanced-api-usage/agent-status-and-events

Retrieves the current agent status and uses a switch statement to perform different actions based on whether the agent is 'online', 'away', or 'offline'. This is useful for tailoring user experiences based on real-time availability.

```javascript
const status = HEYO.getAgentStatus();

switch (status) {
    case 'online':
        console.log('Agent is available to chat');
        break;
    case 'away':
        console.log('Agent is away but may return soon');
        break;
    case 'offline':
        console.log('Agent is offline');
        break;
}
```

--------------------------------

### Show Heyo Widget After User Scrolls with JavaScript

Source: https://heyo.so/docs/getting-started/basic-api-usage

Trigger the Heyo chat widget to appear after a user scrolls a certain distance down the page. This example adds a scroll event listener that calls `HEYO.show()` when the vertical scroll position exceeds 500 pixels.

```javascript
window.addEventListener('scroll', () => {
    if (window.scrollY > 500) {
        HEYO.show();
    }
});
```

--------------------------------

### Conditional Heyo Widget Styling Per Page

Source: https://heyo.so/docs/advanced-api-usage/customizing-appearance

Dynamically change the Heyo widget's appearance based on the current page URL. This allows for different styles on the landing page versus the dashboard, for example.

```javascript
// Landing page - prominent agent card
if (window.location.pathname === '/') {
    HEYO.configure({
        widgetStyle: 'agent-card',
        widgetSize: 'large',
        widgetPosition: 'right',
    });
}

// Dashboard - minimal bubble
if (window.location.pathname.includes('/dashboard')) {
    HEYO.configure({
        widgetStyle: 'bubble',
        widgetSize: 'small',
        widgetPosition: 'left',
    });
}
```

--------------------------------

### Track Onboarding Progress with HEYO SDK

Source: https://heyo.so/docs/advanced-api-usage/tags-and-custom-fields

This snippet demonstrates how to track user progress through an onboarding flow using the HEYO SDK. It involves setting fields for onboarding state and completion, and managing tags to indicate progress status.

```javascript
// Onboarding state
HEYO.setField('onboarding-step', 'profile-setup');
HEYO.setField('onboarding-started', '2025-01-15');
HEYO.setField('completed-steps', 3);

// Tags for each milestone
HEYO.addTag('onboarding-in-progress');

// When user completes onboarding
HEYO.removeTag('onboarding-in-progress');
HEYO.addTag('onboarding-complete');
HEYO.setField('onboarding-step', 'complete');
HEYO.setField('onboarding-completed', '2025-01-20');
```

--------------------------------

### Initialize Heyo Widget with JS SDK Options

Source: https://heyo.so/docs/advanced-api-usage/initialization-options

Initialize the Heyo widget using the JS SDK and pass various configuration options. Supported options include projectId, hidden, and logs. This method is suitable for dynamic configuration within your JavaScript application.

```javascript
import { HEYO } from '@heyo.so/js'; // or: import HEYO from '@heyo.so/js'

HEYO.init({
    projectId: 'YOUR_PROJECT_ID',
    hidden: true,
});

```

```javascript
HEYO.init({
    projectId: '665b12a3b4c5d6e7f8g9h0i1',
});

```

```javascript
HEYO.init({
    projectId: 'YOUR_PROJECT_ID',
    hidden: true,
});

// Show it later when needed
setTimeout(() => {
    HEYO.show();
}, 5000);

```

```javascript
HEYO.init({
    projectId: 'YOUR_PROJECT_ID',
    logs: 'debug', // Options: 'debug', 'minimal', 'none'
});

```

```javascript
// Initialize but keep hidden
HEYO.init({
    projectId: 'YOUR_PROJECT_ID',
    hidden: true,
});

// Check authentication
if (user.isAuthenticated) {
    HEYO.show();
    HEYO.identify({
        userId: user.id,
        email: user.email,
        name: user.name,
    });
}

```

```javascript
const isDevelopment = window.location.hostname === 'localhost';

HEYO.init({
    projectId: isDevelopment ? 'YOUR_PROJECT_ID' : undefined,
    hidden: isDevelopment, // Hide in development
});

```

--------------------------------

### Initialize Heyo Widget with HTML Script Attributes

Source: https://heyo.so/docs/advanced-api-usage/initialization-options

Configure the Heyo widget by setting options as data attributes directly on the HTML script tag. This method is useful for static configuration or when not using a JS SDK. Options like projectId, hidden, and logs can be specified.

```html
<!-- Hidden by default -->
<script src="https://heyo.so/embed/script" defer data-project-id="YOUR_PROJECT_ID" data-hidden="true"></script>

<!-- With debug logging -->
<script src="https://heyo.so/embed/script" defer data-project-id="YOUR_PROJECT_ID" data-logs="debug"></script>

<!-- Multiple options -->
<script src="https://heyo.so/embed/script" defer data-project-id="YOUR_PROJECT_ID" data-hidden="true" data-logs="none"></script>

```

--------------------------------

### Best Practices: Using Custom Fields for Data (HEYO SDK)

Source: https://heyo.so/docs/advanced-api-usage/tags-and-custom-fields

This snippet highlights the recommended approach of using custom fields for specific data points with the HEYO SDK. It shows setting structured data like 'plan', 'billing-cycle', and 'price', and advises against using fields for simple boolean states better represented by tags.

```javascript
// ✅ Good - structured data
HEYO.setField('plan', 'premium');
HEYO.setField('billing-cycle', 'monthly');
HEYO.setField('price', 299);

// ❌ Avoid - boolean states better as tags
HEYO.setField('is-premium', true); // Use tag instead
```

--------------------------------

### Qualify Leads with HEYO SDK

Source: https://heyo.so/docs/advanced-api-usage/tags-and-custom-fields

This code illustrates how to qualify leads using the HEYO SDK by tracking user engagement metrics and adding specific tags based on user actions. It sets fields for page views and time on site, and adds tags like 'qualified-lead', 'hot-lead', and 'enterprise-prospect'.

```javascript
// Track engagement
HEYO.setField('page-views', sessionStorage.pageViewCount);
HEYO.setField('time-on-site', calculateTimeOnSite());
HEYO.setField('last-visit', new Date().toISOString());

// Qualify leads
if (user.downloadedWhitepaper) HEYO.addTag('qualified-lead');
if (user.requestedDemo) HEYO.addTag('hot-lead');
if (user.company.size > 50) HEYO.addTag('enterprise-prospect');
```

--------------------------------

### Set All Tags for Visitors

Source: https://heyo.so/docs/advanced-api-usage/tags-and-custom-fields

Replaces all existing tags on a visitor's profile with a new set of tags. This is useful for comprehensively updating a visitor's categorization.

```javascript
HEYO.setTags(['premium', 'active', 'verified']);
```

--------------------------------

### Execute code when Heyo widget is ready

Source: https://heyo.so/docs/advanced-api-usage/widget-events

The onReady() callback executes code once the Heyo widget is fully loaded and initialized. If the widget is already ready when onReady() is called, the callback runs immediately; otherwise, it's queued. This is useful for actions that depend on the widget's initialization.

```javascript
HEYO.onReady(() => {
    console.log('Widget is ready!');
});
```

```javascript
HEYO.onReady(() => {
    console.log('Heyo widget loaded successfully');
    analytics.track('chat_widget_loaded');
});
```

```javascript
async function initializeChat() {
    const user = await fetchCurrentUser();
    
    HEYO.onReady(() => {
        if (user) {
            HEYO.identify({
                userId: user.id,
                email: user.email,
                name: user.name,
            });
        }
    });
}

initializeChat();
```

```javascript
HEYO.onReady(() => {
    Sentry.addBreadcrumb({
        category: 'chat',
        message: 'Chat widget initialized',
        level: 'info',
    });
});
```

--------------------------------

### Directly call widget methods without onReady

Source: https://heyo.so/docs/advanced-api-usage/widget-events

For most widget methods like identify(), open(), and configure(), explicit use of onReady() is unnecessary. The Heyo SDK automatically queues these calls until the widget is ready, allowing them to be invoked directly after script loading.

```javascript
// ✅ Just call them directly - they're automatically queued
HEYO.identify({ userId: '123' });
HEYO.open();
HEYO.configure({ widgetColor: '#10b981' });
```

--------------------------------

### HEYO.identify() - Basic Identification

Source: https://heyo.so/docs/advanced-api-usage/identifying-users

Identify users by providing their unique ID, email, and name. This helps in linking conversations and providing context to your support team.

```APIDOC
## HEYO.identify()

### Description
Identifies a user and links their conversations to their profile. This allows support teams to see user information and conversation history.

### Method
`HEYO.identify(userData)`

### Parameters
#### Request Body

- Invalid data types for email or name might be ignored or cause unexpected behavior.
```

--------------------------------

### Set Custom Fields for Smart Value Display

Source: https://heyo.so/docs/advanced-api-usage/tags-and-custom-fields

Shows how setting custom fields with specific formats like URLs, emails, dates, booleans, and large numbers results in smart, formatted display in the dashboard.

```javascript
// URLs:
HEYO.setField('website', 'https://example.com');

// Emails:
HEYO.setField('support-email', 'help@acme.com');

// Dates:
HEYO.setField('trial-ends', '2025-02-15');
HEYO.setField('signup-date', '2025-01-15T10:30:00Z');

// Booleans:
HEYO.setField('is-premium', true);
HEYO.setField('trial-expired', false);

// Large Numbers:
HEYO.setField('total-revenue', 125000);
```

--------------------------------

### Set Custom Fields with Supported Value Types

HEYO.setField('plan', 'premium');
HEYO.setField('subscription-id', 'sub_1A2B3C');

// Numbers:
HEYO.setField('account-balance', 1500);
HEYO.setField('total-purchases', 42);

// Booleans:
HEYO.setField('is-verified', true);
HEYO.setField('newsletter-subscribed', false);
```

--------------------------------

### Set Custom Fields for Visitors

Source: https://heyo.so/docs/advanced-api-usage/tags-and-custom-fields

Adds or updates custom key-value data for a visitor. Supports string, number, and boolean types. Field keys are normalized to kebab-case and values are displayed with smart formatting in the dashboard.

```javascript
HEYO.setField('plan', 'premium');
HEYO.setField('signup-date', '2025-01-15');
HEYO.setField('is-subscribed', true);
HEYO.setField('monthly-revenue', 299);
```

--------------------------------

### Prompt Users Before Opening Offline Chat (JavaScript)

Source: https://heyo.so/docs/advanced-api-usage/agent-status-and-events

Attaches an event listener to a chat button. When clicked, it checks agent status. If offline, it prompts the user to confirm if they want to leave a message before forcing the chat open. If online, it opens the chat directly.

```javascript
const chatButton = document.getElementById('chat-button');

chatButton.onclick = () => {
    const status = HEYO.getAgentStatus();
    
    if (status === 'offline') {
        const confirmed = confirm(
            'Our agents are currently offline. Would you like to leave a message?'
        );
        
        if (confirmed) {
            HEYO.open({ force: true });
        }
    } else {
        HEYO.open();
    }
};
```

--------------------------------

### Add Tags to Visitors

Source: https://heyo.so/docs/advanced-api-usage/tags-and-custom-fields

Adds one or more tags to a visitor's profile for categorization. Tags are automatically normalized to kebab-case. This function is useful for segmenting users based on their status or attributes.

```javascript
HEYO.addTag('vip');
HEYO.addTag('paid-user');
HEYO.addTag('onboarding-complete');
```

--------------------------------

### Show and Hide Entire Widget with JavaScript

Source: https://heyo.so/docs/getting-started/basic-api-usage

Control the overall visibility of the Heyo chat widget on the page. The `show()` and `hide()` functions are part of the global `HEYO` object. `HEYO.show({ force: true })` can be used to display the widget even when agents are offline.

```javascript
HEYO.hide(); // Hide the widget completely
HEYO.show(); // Show the widget
HEYO.show({ force: true }); // Show even when agents are offline
```

--------------------------------

### Identify User with Heyo SDK (JavaScript)

Source: https://heyo.so/docs/advanced-api-usage/identifying-users

Identifies a user by providing their email, name, and a unique userId. This allows Heyo to link conversations and user information to your dashboard for personalized support.

```javascript
HEYO.identify({
    email: 'john@example.com',
    name: 'John Doe',
    userId: '12345',
});
```

```javascript
HEYO.identify({
    email: 'sarah@company.com',
    name: 'Sarah Wilson',
    userId: 'user_789',
});
```

```javascript
// When your authentication completes
auth.onLogin((user) => {
    HEYO.identify({
        email: user.email,
        name: user.displayName,
        userId: user.id,
    });
});
```

--------------------------------

### Check Chat Status with JavaScript

Source: https://heyo.so/docs/getting-started/basic-api-usage

Determine if the Heyo chat window is currently open. The `isOpen()` function returns a boolean value, which can be used in conditional logic. This is useful for logging or triggering other actions based on the chat's state.

```javascript
const isChatOpen = HEYO.isOpen();

if (isChatOpen) console.log('Chat is open');
else console.log('Chat is closed');
```

--------------------------------

### Agent Status API

Source: https://heyo.so/docs/advanced-api-usage/agent-status-and-events

This section covers methods for retrieving the current agent status and subscribing to status change events.

```APIDOC
## Agent Status API

### Description

const status = HEYO.getAgentStatus();

switch (status) {
    case 'online':
        console.log('Agent is available to chat');
        break;
    case 'away':
        console.log('Agent is away but may return soon');
        break;
    case 'offline':
        console.log('Agent is offline');
        break;
}
```

```
```

--------------------------------

### Force Show/Open Widget When Offline

Source: https://heyo.so/docs/advanced-api-usage/agent-status-and-events

Overrides the 'hide when offline' behavior to force the widget to show or open even when all agents are offline. This is useful for allowing users to leave messages when no agents are immediately available.

```javascript
// Show the widget even if hideWhenOffline is enabled and all agents are offline
HEYO.show({ force: true });

// Open the chat even if hideWhenOffline is enabled and all agents are offline
HEYO.open({ force: true });
```

--------------------------------

### Check Status Before Opening Chat (JavaScript)

Source: https://heyo.so/docs/advanced-api-usage/agent-status-and-events

Checks the current agent status before attempting to open the chat. If agents are offline, it alerts the user and then forces the chat open to allow message submission. Otherwise, it opens the chat normally.

```javascript
const status = HEYO.getAgentStatus();

if (status === 'online') {
    HEYO.open();
} else {
    alert('Our support team is currently offline. Please leave a message!');
    HEYO.open({ force: true }); // Open anyway to leave a message
}
```

--------------------------------

### Listen for Agent Status Changes

Source: https://heyo.so/docs/advanced-api-usage/agent-status-and-events

Subscribes to real-time updates for agent status changes using the `onAgentStatusChange` callback. This function is executed whenever an agent's status transitions, allowing your application to react dynamically.

```javascript
HEYO.onAgentStatusChange((status) => {
    console.log('Agent is now:', status);
});
```

--------------------------------

### Control Heyo Chat from HTML Button

Source: https://heyo.so/docs/getting-started/basic-api-usage

Integrate Heyo chat functionality directly into HTML elements, such as a button. The `onclick` event handler can call `HEYO.open()` to launch the chat window when the button is clicked.

```html
<button onclick="HEYO.open()">Contact Support</button>
```

--------------------------------

### Open, Close, and Toggle Chat Window with JavaScript

Source: https://heyo.so/docs/getting-started/basic-api-usage

Control the expanded or collapsed state of the Heyo chat window. These functions are available on the global `HEYO` object and work with both the HTML script tag and the JS SDK. An optional parameter `{ force: true }` can override the 'Hide when offline' setting.

```javascript
HEYO.open(); // Open the chat window
HEYO.close(); // Close the chat window
HEYO.toggle(); // Toggle between open and closed

// Override the "hide when offline" setting and show the widget anyway
HEYO.open({ force: true });
```

--------------------------------

### HEYO.logout() - Manual Logout

Source: https://heyo.so/docs/advanced-api-usage/identifying-users

Explicitly clear the current user session using the logout() method, typically called when a user logs out of your application.

```APIDOC
## HEYO.logout()

### Description
Clears the current user session, resets the widget state, and logs the user out from Heyo tracking. This is useful when a user explicitly logs out of your application.

### Method
`HEYO.logout()`

### Parameters
This method does not accept any parameters.

### Request Example
```javascript
HEYO.logout();
```

### Response
This method does not return a response. It clears session cookies and resets the widget state locally.
```

--------------------------------

### Widget Visibility Control

Source: https://heyo.so/docs/advanced-api-usage/agent-status-and-events

Control the visibility of the Heyo widget based on agent online status and override default behavior.

```APIDOC
## Widget Visibility Control

### Description
Manage the Heyo widget's visibility, particularly when agents are offline. By default, the widget can be configured to hide when all agents are offline. You can also force the widget to show or open even when agents are offline.

### Hide Widget When Offline

#### Description
When enabled in Project Settings, the widget automatically hides if all agents go offline. It reappears when agents come online only if the user has shown interest (e.g., by calling `HEYO.open()` or `HEYO.show()`).

#### How it works:
- Page loads with all agents offline → widget stays hidden.
- Page loads with agents online → widget shows normally.
- Widget was visible, agents go offline → widget hides.
- Widget was visible before going offline, agents come back online → widget re-appears.
- Widget was never shown, agents come online → widget stays hidden (respects user preference).

### Force Showing/Opening When Offline

#### Description
Override the "hide when offline" behavior to ensure the widget is visible or open even if no agents are available.

#### Methods

##### `show({ force: true })`

- **Description**: Forces the widget to show, even if the 'Hide when offline' setting is enabled and all agents are offline.
- **Example**: `HEYO.show({ force: true });`

##### `open({ force: true })`

- **Description**: Forces the chat to open, even if the 'Hide when offline' setting is enabled and all agents are offline.
- **Example**: `HEYO.open({ force: true });`

#### Use Case
Useful when you want to provide users the option to leave a message even when no agents are available.

### Execute code when agent status changes

Source: https://heyo.so/docs/advanced-api-usage/widget-events

The onAgentStatusChange() callback executes code when the agent's status transitions. It's called immediately with the current status upon registration and subsequently whenever the status changes. The callback receives one of three status values: 'online', 'away', or 'offline'.

```javascript
HEYO.onAgentStatusChange((status) => {
    console.log('Agent status changed to:', status);
    
    if (status === 'online') {
        showNotification('Support is now available!');
    }
});
```

```javascript
const statusIndicator = document.getElementById('support-status');

HEYO.onAgentStatusChange((status) => {
    if (status === 'online') {
        statusIndicator.textContent = '🟢 Chat available';
        statusIndicator.style.color = '#22c55e';
    } else if (status === 'away') {
        statusIndicator.textContent = '🟡 Be right back';
        statusIndicator.style.color = '#f59e0b';
    } else {
        statusIndicator.textContent = '⚫ Leave a message';
        statusIndicator.style.color = '#6b7280';
    }
});
```

```javascript
let hasPrompted = false;

HEYO.onAgentStatusChange((status) => {
    if (status === 'online' && !hasPrompted) {
        hasPrompted = true;
        setTimeout(() => HEYO.open(), 3000);
    }
});
```

```javascript
HEYO.onAgentStatusChange((status) => {
    updateSupportButton(status);
});

HEYO.onAgentStatusChange((status) => {
    analytics.track('agent_status_changed', { status });
});
```
