This guide shows you how to use Google Mobile Ads Flutter Plugin to load and display
ads from DT Exchange using
[mediation](https://developers.google.com/ad-manager/mobile-ads-sdk/flutter/mediation.md.txt), covering waterfall integrations. It covers how
to add DT Exchange to an ad unit's
mediation configuration, and how to integrate the
DT Exchange SDK and adapter into a
Flutter app.

## Supported integrations and ad formats

The Flutter mediation adapter for
DT Exchange has the following
capabilities:

| Integration ||
|---|---|
| Bidding | Yes |
| Waterfall | Yes |
| App Open |   |
| Banner | Yes |

- ![User Profile](https://developers.google.com/static/admob/images/mediation/dtexchange/DTExchange-User-Profile.png)

### Update your app-ads.txt

- [Authorized Sellers for Apps app-ads.txt](https://iabtechlab.com/wp-content/uploads/2019/03/app-ads.txt-v1.0-final-.pdf) is an IAB Tech Lab initiative that helps ensure your app ad inventory is only sold through channels you've identified as authorized. To prevent a significant loss in ad revenue, you'll need to implement an `app-ads.txt` file. If you haven't done so already, [create an app-ads.txt file for Ad Manager](https://support.google.com/admanager/answer/7544382).
- To implement `app-ads.txt` for DT Exchange, [Add DT to your app-ads.txt file](https://developer.digitalturbine.com/hc/en-us/articles/360009975198-app-ads-txt#01FN8J1SFM3HS6YBNZTG07HYYE).

## Step 2: Set up DT Exchange demand in Ad Manager UI

### Configure mediation settings for your ad unit

### Android

For instructions, see step 2 in the guide for

[Android](https://developers.google.com/ad-manager/mobile-ads-sdk/android/mediation/dt-exchange.md.txt#step-2).

### iOS

For instructions, see step 2 in the guide for

[iOS](https://developers.google.com/ad-manager/mobile-ads-sdk/ios/mediation/dt-exchange.md.txt#step-2).

### Add DT Exchange to GDPR and US state regulations ad partners list

- Follow the steps in [European regulations settings](https://support.google.com/admanager/answer/10113006#adding_ad_partners_to_published_gdpr_messages) and [US state regulations settings](https://support.google.com/admanager/answer/14117973) to add **DT Exchange (Fyber Monetization)** to the European and US state regulations ad partners list in the Ad Manager UI.

## Step 3: Import the DT Exchange SDK and adapter

> [!NOTE]
> **Note:** Failure to integrate the compatible DT Exchange and Google Mobile Ads Flutter Plugin versions might lead to build issues.

### Integration through pub.dev

- Add the following dependency with the latest versions of the DT Exchange SDK and adapter in your package's `pubspec.yaml` file:

```yaml
dependencies:
  gma_mediation_dtexchange: ^1.4.0
```

### Manual Integration

- Download the latest version of Google Mobile Ads mediation plugin for [DT Exchange](https://pub.dev/packages/gma_mediation_dtexchange/versions), extract the downloaded file, and add the extracted plugin folder (and its contents) to your Flutter project. Then, reference the plugin in your `pubspec.yaml` file by adding the following dependency:

```yaml
dependencies:
  gma_mediation_dtexchange:
    path: path/to/local/package
```

## Step 4: Implement privacy settings on DT Exchange SDK

### EU consent and GDPR

- To [comply with
  the Google EU User Consent Policy](https://www.google.com/about/company/consentstaging.html), you must make certain disclosures to your users in the European Economic Area (EEA), the UK, and Switzerland, and obtain their consent for the use of cookies or other local storage where legally required, and for the collection, sharing, and use of personal data for ads personalization. This policy reflects the requirements of the EU ePrivacy Directive and the General Data Protection Regulation (GDPR). You are responsible for verifying that consent is propagated to each ad source in your mediation chain.
- DT Exchange Flutter adapter version 1.1.0 and later supports passing GDPR consent signals from consent management platforms that integrate with IAB's Transparency and Consent Framework (TCF) to DT Exchange SDK. For more information, see [Android](https://docs.digitalturbine.com/dt-exchange/sdk-configuration/integrating-the-android-sdk#gdpr) and [iOS](https://docs.digitalturbine.com/dt-exchange/sdk-configuration/integrating-the-ios-sdk#h_01j64gft6cdgx97eyg11t7dfyf) GDPR documentation.

### US states privacy laws

- [US states privacy laws](https://support.google.com/admanager/answer/9561023) require giving users the right to opt out of the "sale" of their "personal information" (as the law defines those terms), with the opt-out offered through a prominent "Do Not Sell My Personal Information" link on the "selling" party's homepage. The [US states privacy
  laws compliance guide](https://developers.google.com/ad-manager/mobile-ads-sdk/flutter/privacy/us-states) offers the ability to enable [restricted data processing](https://privacy.google.com/businesses/rdp/) for Google ad serving, but Google is unable to apply this setting to each ad network in your mediation chain. Therefore, you must identify each ad network in your mediation chain that may participate in the sale of personal information and follow guidance from each of those networks to ensure compliance.
- The Google Mobile Ads mediation plugin for DT Exchange does not support passing consent information to the DT Exchange SDK.

## Step 5: Add required code

### Android

No additional code is required for
DT Exchange integration.

### iOS

### SKAdNetwork integration

Follow [DT Exchange's
documentation](https://developer.digitalturbine.com/hc/en-us/articles/360011979758-Marketplace-Publisher-info-plist-iOS-14-SKAdNetwork-Checklist-)
to add the SKAdNetwork identifiers to your project's `Info.plist` file.

## Step 6: Test your implementation

### Enable test ads

- Make sure you [register your test device](https://developers.google.com/ad-manager/mobile-ads-sdk/flutter/test-ads.md.txt#enable_test_devices) for Ad Manager.

> [!IMPORTANT]
> **Important:** Disable test mode for Ad Manager and DT Exchange before releasing your app.

### Verify test ads

- To verify that you are receiving test ads from DT Exchange, enable [single ad source testing](https://developers.google.com/ad-manager/mobile-ads-sdk/flutter/ad-inspector.md.txt#single_ad_source_testing) in ad inspector using the **DT Exchange (Bidding) and DT Exchange (Waterfall)** ad source(s).

## Error codes

- If the adapter fails to receive an ad from DT Exchange, publishers can check the underlying error from the ad response using [`ResponseInfo`](https://developers.google.com/ad-manager/mobile-ads-sdk/flutter/response-info.md.txt) under the following class:

### Android

```java
com.google.ads.mediation.fyber.FyberMediationAdapter
```

### iOS

```objective-c
GADMediationAdapterFyber
```
- Here are the codes and accompanying messages thrown by the DT Exchange adapter when an ad fails to load:

### Android

| Error code | Reason |
|---|---|
| 101 | DT Exchange server parameters configured in the Ad Manager UI are missing/invalid. |
| 103 | The requested ad size does not match a DT Exchange supported banner size. |
