Banner Integration for Unity

Banners are a rectangular, system-initiated ads that can be either static or animated, and are served in a designated area around your live app content. 

Before you start Make sure that you have correctly integrated the ironSource Unity Plugin into your application. Integration is outlined here.

Step 1. Load Banner Ad

To load a Banner ad, call the following method:

  • Load the Banner view by calling this method (in this example it’s the BANNER banner size):
    IronSource.Agent.loadBanner(IronSourceBannerSize.BANNER, IronSourceBannerPosition.BOTTOM);
    See table below for details about our supported standard banner sizes:
    IronSourceBannerSize Description Dimensions (WxH) (points in iOS, dp in Android)
    BANNER Standard Banner 320 x 50
    LARGE Large Banner 320 x 90
    RECTANGLE Medium Rectangular Banner 300 x 250
    Smart Banner
    (Adjusted for both mobile and tablet)
    If (iPhone) 320 x 50
    If (iPad) 728 x 90
    If (screen width ≤ 720) 320 x 50
    If (screen width > 720) 728 x 90

    See table below for details about our supported standard banner positions:

    IronSourceBannerPosition Description
    TOP Banner will be positioned at the top center of the screen
    BOTTOM Banner will be positioned at the bottom center of the screen
  • Another option is initiating the banner with Custom size, using this signature (WxH) (points in iOS, dp in Android):
    IronSource.Agent.loadBanner(new IronSourceBannerSize(320, 50), IronSourceBannerPosition.BOTTOM);

You will receive the onBannerAdLoadedEvent and the banner will show on your app.

Hide & Display Banner – Optional

In order to provide maximum flexibility in the ad experience, you now have the ability to hide and present banners on your app.

Unlike with the Android and iOS native implementations, when banner is loaded for the first time in Unity, it will show itself, and there won’t be a need to call displayBanner().

Once you’ve loaded and served a banner, you can choose to hide this banner and re-show it at a later point in your app.

To hide the banner, call this function:


To then show this same banner again, call this function:


    Step 2. Implement the Banner Events

    The ironSource Unity Plugin fires several events to inform you of ad availability and activity. Under IronSource/Assets/Prefabs, you’ll find the IronSourceEventsPrefab. Add it to your project to receive these events.

    public class VideoScript : MonoBehaviour {
      void Start() 
        IronSourceEvents.onBannerAdLoadedEvent += BannerAdLoadedEvent;
        IronSourceEvents.onBannerAdLoadFailedEvent += BannerAdLoadFailedEvent;        
        IronSourceEvents.onBannerAdClickedEvent += BannerAdClickedEvent; 
        IronSourceEvents.onBannerAdScreenPresentedEvent += BannerAdScreenPresentedEvent; 
        IronSourceEvents.onBannerAdScreenDismissedEvent += BannerAdScreenDismissedEvent;
        IronSourceEvents.onBannerAdLeftApplicationEvent += BannerAdLeftApplicationEvent;
    //Invoked once the banner has loaded
    void BannerAdLoadedEvent() {
    //Invoked when the banner loading process has failed.
    //@param description - string - contains information about the failure.
    void BannerAdLoadFailedEvent (IronSourceError error) {
    // Invoked when end user clicks on the banner ad
    void BannerAdClickedEvent () {
    //Notifies the presentation of a full screen content following user click
    void BannerAdScreenPresentedEvent () {
    //Notifies the presented screen has been dismissed
    void BannerAdScreenDismissedEvent() {
    //Invoked when the user leaves the app
    void BannerAdLeftApplicationEvent() {

    Step 3. Additional Load Settings

    We support placements, as well as capping and pacing for Banners on the ironSource dashboard. Learn how to set up placements, capping and pacing for Banners to optimize your app’s user experience here.

    If you’ve set up placements for your Banner, call the following method to serve a Banner ad in a specific location:

    IronSource.Agent.loadBanner(IronSourceBannerSize.BANNER, IronSourceBannerPosition.BOTTOM, (string) "YOUR_PLACEMENT_NAME");

    Note:  Note: SDK will not show more than one banner at a time.

    Step 4. Destroy the Banner Ad

    To destroy a banner, call the following method:


    A destroyed banner can no longer be loaded. If you want to serve it again, you must initiate it again.

    Step 5.  Integrate a Banner Provider

    Next, integrate the ad network adapters to serve Banners through ironSource Mediation.

    You can find the supported networks below, and bannerSize behaviour for each network, as defined for relevant platform: 

    iOS Banner Support 

    Android Banner Support 


    You are now all set up to serve Banners in your application. Verify your integration with our Integration Helper.
