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.

Bidding

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.

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.

Update your app-ads.txt

Authorized Sellers for Apps app-ads.txt 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, set up an app-ads.txt file for your app.

To implement app-ads.txt for InMobi, Add your personalized code snippet.

Turn on test mode

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

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

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

Step 3: Import the InMobi SDK and adapter

OpenUPM-CLI

If you have OpenUPM-CLI installed, you can install the Google Mobile Ads InMobi Mediation Plugin for Unity to your project by running the following command from your project's root directory:

openupm add com.google.ads.mobile.mediation.inmobi

OpenUPM

In your Unity project editor, select Edit > Project Settings > Package Manager to open the Unity Package Manager Settings.

Under the Scoped Registries tab, add OpenUPM as a scoped registry with the following details:

  • Name: OpenUPM
  • URL: https://package.openupm.com
  • Scope(s): com.google

OpenUPM Details

Then, navigate to Window > Package Manager to open the Unity Package Manager and select My Registries from the drop-down menu.

Unity Registries

Select the Google Mobile Ads InMobi Mediation package and click Install.

Install from OpenUPM

Unity Package

Download the latest version of Google Mobile Ads mediation plugin for InMobi from the download link in the Changelog and extract the GoogleMobileAdsInMobiMediation.unitypackage from the zip file.

In your Unity project editor, select Assets > Import Package > Custom Package and find the GoogleMobileAdsInMobiMediation.unitypackage file you downloaded. Make sure that all the files are selected and click Import.

Import from Unity

Then, select Assets > External Dependency Manager > Android Resolver > Force Resolve. The External Dependency Manager library will perform dependency resolution from scratch and copy the declared dependencies into the Assets/Plugins/Android directory of your Unity app.

Force Resolve

Step 4: Implement privacy settings on InMobi 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 InMobi version 2.1.0 added the InMobi.UpdateGDPRConsent() method that lets you pass consent information to InMobi. The following sample code shows how to pass consent information to the InMobi SDK. If you choose to call this method, we recommend that you do so prior to requesting ads with the Google Mobile Ads SDK.

using GoogleMobileAds.Api.Mediation.InMobi;
using System.Collections.Generic;
// ...

Dictionary<string, string> consentObject = new Dictionary<string, string>();
consentObject.Add("gdpr_consent_available", "true");
consentObject.Add("gdpr", "1");

InMobi.UpdateGDPRConsent(consentObject);

See InMobi's GDPR implementation details for more information about the possible keys and values that InMobi accepts in this consent object.

US states privacy laws

US 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 through a prominent "Do Not Sell My Personal Information" link on the "selling" party's homepage. The US 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.

See InMobi's CCPA documentation for guidelines on how to enable CCPA settings for InMobi.

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.

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:
