Handle onboarding events in Capacitor SDK

Onboardings configured with the builder generate events your app can respond to. Use the setEventHandlers method to handle these events for standalone screen presentation.

Before you start, ensure that:

1. You have created an onboarding.
2. You have added the onboarding to a placement.

Set up event handlers

To handle events for onboardings, use the view.setEventHandlers method:

import { adapty, createOnboardingView } from '@adapty/capacitor';

try {
  const view = await createOnboardingView(onboarding);
  
  view.setEventHandlers({
    onAnalytics(event, meta) {
      console.log('Analytics event:', event);
    },
    onClose(actionId, meta) {
      console.log('Onboarding closed:', actionId);
      return true; // Allow the onboarding to close
    },
    onCustom(actionId, meta) {
      console.log('Custom action:', actionId);
      return false; // Don't close the onboarding
    },
    onPaywall(actionId, meta) {
      console.log('Paywall action:', actionId);
    },
    onStateUpdated(action, meta) {
      console.log('State updated:', action);
    },
    onFinishedLoading(meta) {
      console.log('Onboarding finished loading');
    },
    onError(error) {
      console.error('Onboarding error:', error);
    },
  });
  
  await view.present();
} catch (error) {
  console.error('Failed to present onboarding:', error);
}

Event types

The following sections describe the different types of events you can handle.

Handle custom actions

In the builder, you can add a custom action to a button and assign it an ID.

Then, you can use this ID in your code and handle it as a custom action. For example, if a user taps a custom button, like Login or Allow notifications, the event handler will be triggered with the actionId parameter that matches the Action ID from the builder. You can create your own IDs, like "allowNotifications".

view.setEventHandlers({
  onCustom(actionId, meta) {
    switch (actionId) {
      case 'login':
        console.log('Login action triggered');
        break;
      case 'allow_notifications':
        console.log('Allow notifications action triggered');
        break;
    }
    return false; // Don't close the onboarding
  },
});

{
  "actionId": "allow_notifications",
  "meta": {
    "onboardingId": "onboarding_123",
    "screenClientId": "profile_screen",
    "screenIndex": 0,
    "screensTotal": 3
  }
}

Finishing loading onboarding

When an onboarding finishes loading, this event will be triggered:

view.setEventHandlers({
  onFinishedLoading(meta) {
    console.log('Onboarding loaded:', meta.onboardingId);
  },
});

Event example (Click to expand)

{
    "meta": {
        "onboarding_id": "onboarding_123",
        "screen_cid": "welcome_screen",
        "screen_index": 0,
        "total_screens": 4
    }
}

Closing onboarding

Onboarding is considered closed when a user taps a button with the Close action assigned.

important

Note that you need to manage what happens when a user closes the onboarding. For instance, you need to stop displaying the onboarding itself.

view.setEventHandlers({
  onClose(actionId, meta) {
    console.log('Onboarding closed:', actionId);
    return true; // Allow the onboarding to close
  },
});

Event example (Click to expand)

{
  "action_id": "close_button",
  "meta": {
    "onboarding_id": "onboarding_123",
    "screen_cid": "final_screen",
    "screen_index": 3,
    "total_screens": 4
  }
}

Opening a paywall

tip

Handle this event to open a paywall if you want to open it inside the onboarding. If you want to open a paywall after it is closed, there is a more straightforward way to do it – handle the close action and open a paywall without relying on the event data.

If a user clicks a button that opens a paywall, you will get a button action ID that you set up manually. The most seamless way to work with paywalls in onboardings is to make the action ID equal to a paywall placement ID:

view.setEventHandlers({
  onPaywall(actionId, meta) {
    console.log('Paywall action triggered:', actionId);
    // Implement your paywall opening logic here
  },
});

Event example (Click to expand)

{
    "action_id": "premium_offer_1",
    "meta": {
        "onboarding_id": "onboarding_123",
        "screen_cid": "pricing_screen",
        "screen_index": 2,
        "total_screens": 4
    }
}

Tracking navigation

You receive an analytics event when various navigation-related events occur during the onboarding flow:

view.setEventHandlers({
  onAnalytics(event, meta) {
    console.log('Analytics event:', event.type, meta.onboardingId);
  },
});

The event object can be one of the following types:

Type	Description
onboardingStarted	When the onboarding has been loaded
screenPresented	When any screen is shown
screenCompleted	When a screen is completed. Includes optional elementId (identifier of the completed element) and optional reply (response from the user). Triggered when users perform any action to exit the screen.
secondScreenPresented	When the second screen is shown
userEmailCollected	Triggered when the user's email is collected via the input field
onboardingCompleted	Triggered when a user reaches a screen with the final ID. If you need this event, assign the final ID to the last screen.
unknown	For any unrecognized event type. Includes name (the name of the unknown event) and meta (additional metadata)

Each event includes meta information containing:

Field	Description
onboardingId	Unique identifier of the onboarding flow
screenClientId	Identifier of the current screen
screenIndex	Current screen's position in the flow
screensTotal	Total number of screens in the flow
