Add Fyber to GDPR and US state regulations ad partners list

Follow the steps in GDPR settings and US state regulations settings to add Fyber to the GDPR and US state regulations ad partners list in the Ad Manager UI.

Step 3: Import the DT Exchange SDK and adapter

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:

dependencies:
  gma_mediation_dtexchange: ^1.0.0

Manual Integration

Download the latest version of Google Mobile Ads mediation plugin for DT Exchange, 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:

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

Step 4: Implement privacy settings on DT Exchange SDK

Under the Google EU User Consent Policy, you must ensure that certain disclosures are given to, and consents obtained from, users in the European Economic Area (EEA) regarding the use of device identifiers and personal data. This policy reflects the requirements of the EU ePrivacy Directive and the General Data Protection Regulation (GDPR). When seeking consent, you must identify each ad network in your mediation chain that may collect, receive, or use personal data and provide information about each network's use. Google currently is unable to pass the user's consent choice to such networks automatically.

The Google Mobile Ads mediation plugin for DT Exchange does not support passing consent information to the DT Exchange SDK.

US states privacy laws

U.S. states privacy laws 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 via a prominent "Do Not Sell My Personal Information" link on the "selling" party's homepage. The U.S. states privacy laws compliance guide offers the ability to enable restricted data processing 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 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 for Ad Manager.

Verify test ads

To verify that you are receiving test ads from DT Exchange, enable single ad source testing in ad inspector using the DT Exchange (Waterfall) ad source(s).
