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

Create a placement

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

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.

Select Banner as the type and click Add a placement. Then enter a Placement Name. Click the Create Placement button when done.

Interstitial

Select Interstitial as the type and click Add a placement. Then enter a Placement Name. Click the Create Placement button when done.

In the InMobi Publisher Dashboard, go to My Account > Account Settings, click the API Key tab, and then 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 admin 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 email on the API Key tab.

Step 2: Configure AdMob ad unit

First, sign in to your AdMob account. Next, follow the instructions below to create an AdMob ad unit and configure it to mediate for InMobi. If you plan to deploy your Unity app to both Android and iOS, you'll need to run through both the Android and iOS sections to create an AdMob ad unit for each platform.

AdMob UI Android

Navigate to the Mediation tab. If you have an existing mediation group you would like to modify, click the name of that mediation group to edit it, and skip ahead to Add InMobi as an ad source.

To create a new mediation group, select Create Mediation Group.

Enter your ad format and platform, then click Continue.

Give your mediation group a name, and select locations to target. Next, set the mediation group status to Enabled.

Then click Add Ad Units.

Associate this mediation group with one or more of your existing AdMob ad units. Then click Done.

Notice that the ad units card is now populated with the ad units you selected, as shown below:

Add InMobi as an ad source

In the Ad Sources card, select Add Ad Network.

Select InMobi and enable the Optimize switch. Enter your Login name and the API key with the username and API Key fields obtained in the previous section to set up ad source optimization for InMobi. Then enter an eCPM value for InMobi and click Continue.

Enter the Account ID and the Placement ID obtained in the previous section.

AdMob UI iOS

Navigate to the Mediation tab. If you have an existing mediation group you'd like to modify, click the name of that mediation group to edit it, and skip ahead to Add InMobi as an ad source. To create a new mediation group, select Create Mediation Group.

Enter your ad format and platform, then click Continue.

Give your mediation group a name, and select locations to target.

Next, set the mediation group status to Enabled. Then click Add Ad Units.

Associate this mediation group with one or more of your existing AdMob ad units. Then click Done.

Notice that the ad units card is now populated with the ad units you selected, as shown below:

Add InMobi as an ad source

In the Ad Sources card, select Add Ad Network.

Select InMobi and enable the Optimize switch. Enter your Login name and the API key obtained in the previous section to set up ad source optimization for InMobi. Then enter an eCPM value for InMobi, check the authorization checkbox, and click Continue.

Enter the Account ID and the Placement ID obtained in the previous section.

Using rewarded ads

In the settings for your rewarded ad unit, check the Apply to all networks in Mediation groups box so that you provide the same reward to the user no matter which ad network is served.

If you don't check this setting, the InMobi adapter passes back the reward specified in the InMobi dashboard when creating the placement.

For more information on setting reward values for AdMob ad units, refer to Create an ad unit.

Step 3: Import the InMobi SDK and adapter

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

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

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

Step 4: Add required additional code

No additional code required for InMobi integration.

Step 5: Test your implementation

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

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.

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.

Add InMobi to GDPR ad partners list

Follow the steps in GDPR settings to add InMobi to the GDPR ad partners list in the AdMob UI.

CCPA

The California Consumer Privacy Act (CCPA) requires giving California state residents 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 CCPA preparation 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 with CCPA.

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

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:
