Integrate InMobi with mediation

This guide shows you how to use the Google Mobile Ads SDK to load and display ads from InMobi using mediation, covering both waterfall and bidding integrations. It covers how to add InMobi to an ad unit's mediation configuration, and how to integrate the InMobi SDK and adapter into a Flutter app.

Step 1: Set up configurations in InMobi UI

Sign up for an InMobi account. When creating an account, leave the Use InMobi SSP with Google Open Bidding option unchecked.

Once your account is verified, log in.

Add an app

To add your app to the InMobi dashboard, click Inventory > Inventory Settings.

Click Add Inventory and select the Mobile App channel from the drop-down menu.

Start typing your published app store URL in the search bar and select the app from the auto-populated results. Click Continue.

If your app in not published, click Link manually and enter the required details. Click Continue.

Review the App & Website Compliance settings and then click Save and Create Placements.

Placements

After you set up your inventory, the system redirects you to the placement creation workflow.

Note: If the system does not redirect you to the placement creation workflow, go to Inventory > Inventory Settings. Then, search for the app or website you would like to create a placement for. Click Add a placement.

Bidding

Note: Contact your account manager to get access for configuring bidding in the InMobi dashboard.

Select the type of ad unit. The enter a Placement Name, select On and Google Open Bidding for Audience Bidding and Partner respectively, and fill out the rest of the form. Click Create Placement when done.

Waterfall

Select the type of ad unit. Then enter a Placement Name, select Off for Audience Bidding, and fill out the rest of the form. Click Create Placement when done.

Once the placement is created, its details are shown. Take note of the Placement ID, which will be used for setting up your AdMob ad unit.

Note: The InMobi Placement ID is present under the placement name.

Account ID

Your InMobi account ID is available under Finance > Payment Settings > Payment Information.

Locate InMobi Reporting API Key

Bidding

This step isn't required for bidding integrations.

Waterfall

Go to My Account > Account Settings. Navigate to the API Key tab and click Generate API Key.

Select the email of the user the key is required for and click Generate API Key. A file containing the API key and username/login name will be generated.

Only the publisher administrator of the account will be able to generate an API key for all users. If you have forgotten the previously generated API key, reset your API key by hovering over your mail on the API Key tab.

Turn on test mode

Enable Test Mode for your placement on all live impressions or certain test devices only.

Note: Test mode is turned Off by default for all placements. However, test mode can be enabled for placements across all app instances or only for devices you specify.

Step 2: Set up InMobi demand in AdMob UI

Configure mediation settings for your ad unit

Android

For instructions, see step 2 in the guide for Android.

iOS

For instructions, see step 2 in the guide for iOS.

Add InMobi to GDPR and US state regulations ad partners list

Important: Verify that you have Account Management permission to complete the configuration for EU Consent and GDPR, CPRA, and User Messaging Platform. See Manage user access to your account for details.

Follow the steps in GDPR settings and US state regulations settings to add InMobi to the GDPR and US state regulations ad partners list in the AdMob UI.

Step 3: Import the InMobi SDK and adapter

Note: Failure to integrate the compatible InMobi and Google Mobile Ads SDK versions might lead to build issues.

Integration through pub.dev

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

dependencies:
  gma_mediation_inmobi: ^1.0.0

Manual Integration

Download the latest version of Google Mobile Ads mediation plugin for InMobi, 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_inmobi:
    path: path/to/local/package

Step 4: Implement privacy settings on InMobi SDK

EU consent and GDPR

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 InMobi does not support passing consent information to the InMobi 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 InMobi does not support passing consent information to the InMobi SDK.

Step 5: Add required additional code

Android

No additional code is required InMobi integration.

iOS

SKAdNetwork integration

Follow InMobi'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 AdMob and enable test mode in InMobi UI.

Important: Disable test mode for AdMob and InMobi before releasing your app.

Verify test ads

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

Optional steps

Android

Permissions

For optimal performance, InMobi recommends adding the following optional permissions to your app's AndroidManifest.xml file.

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />

You may optionally add these permissions to the Plugins/Android/GoogleMobileAdsInMobiMediation/AndroidManifest.xml file.

iOS

No additional steps required for iOS integration.

Error codes

If the adapter fails to receive an ad from InMobi, publishers can check the underlying error from the ad response using ResponseInfo under the following classes:

Android

com.google.ads.mediation.inmobi.InMobiAdapter
com.google.ads.mediation.inmobi.InMobiMediationAdapter

iOS

GADMAdapterInMobi
GADMediationAdapterInMobi

Here are the codes and accompanying messages thrown by the InMobi adapter when an ad fails to load:

Android

Error code	Reason
0-99	InMobi SDK Errors. See code for more details.
100	InMobi server parameters configured in the AdMob UI are missing/invalid.
101	Failed to initialize the InMobi SDK.
102	The requested ad size does not match an InMobi supported banner size.
103	Ad request is not a unified native ad request.
104	Attempted to request an InMobi ad without initializing the InMobi SDK. This should in theory never happen since the adapter initializes the InMobi SDK prior to requesting InMobi ads.
105	InMobi's ad is not yet ready to be shown.
106	InMobi failed to display an ad.
107	InMobi returned a native ad that is missing a required asset.

Error code	Reason
101	InMobi server parameters configured in the AdMob UI are missing/invalid.
102	InMobi Adapter does not support the ad format being requested.
103	An InMobi ad is already loaded for this network configuration.
