Ad unit mappings

Ad unit mappings are third-party configuration settings that map to an AdMob ad unit and enable it to make an ad request to a third-party ad network.

When creating a mediation group, ad unit mappings are used as a parameter for each mediation group line as settings for the specified ad unit to make third-party ad network requests. Unlike on the AdMob UI, ad unit mappings need to be created independently outside of mediation groups and mediation group lines. After creation, you can list all ad unit mappings and use them as a parameter when creating or updating mediation group lines with new ad unit mappings.

Examples

With OAuth 2.0 credentials created, you're ready to start using the AdMob API. To request access using OAuth 2.0, your application will also need the scope information.

Here's the OAuth 2.0 scope information:

Scope	Meaning
`https://www.googleapis.com/auth/admob.monetization`	See, create, and edit your AdMob monetization settings.
`https://www.googleapis.com/auth/admob.readonly`	See all AdMob data. This may include account information, inventory and mediation settings, reports, and other data. This doesn't include sensitive data, such as payments or campaign details.

Get started on creating your first ad unit mapping:

curl (command line)

Requests using curl

Load the client secrets file and generate authorization credentials.

The first time you perform this step you'll be asked to accept an authorization prompt in your browser. Before accepting, make sure you're signed in with a Google Account that has access to the AdMob API. Your application will be authorized to access data on behalf of whichever account is currently logged in.

For authentication and authorization, we recommend using oauth2l, a simple command-line tool for working with Google OAuth 2.0. Install oauth2l and run the command below, replacing path_to_credentials_json with a path to a credentials.json file that you download when registering your cloud application. For the first run, the command walks you through the OAuth 2.0 authorization flow. Subsequent runs refresh the token automatically.
```
oauth2l header --json path_to_credentials_json --scope admob.readonly,admob.monetization
```

List ad sources.

Get AdMob ad source information by replacing pub-XXXXXXXXXXXXXXXX with your publisher ID. See the instructions on how to find your publisher ID.

curl --http1.0 -X GET https://admob.googleapis.com/v1beta/accounts/pub-XXXXXXXXXXXXXXXX/adSources \
 -H "$(oauth2l header --json path_to_credentials_json --scope admob.readonly)"

Sample response:

{
 "adSources": [
   {
     "name": "accounts/pub-XXXXXXXXXXXXXXXX/adSources/5450213213286189855",
     "adSourceId": "5450213213286189855",
     "title": "AdMob Network",
   }
 ]
}

List the adapters.

Replace SSSSSSSSSSSSSSSSSSSS with the ad source ID for the adapters of interest.

Use the following command to get a list of adapters:

curl --http1.0 -X GET https://admob.googleapis.com/v1beta/accounts/pub-XXXXXXXXXXXXXXXX/adSources/SSSSSSSSSSSSSSSSSSSS/adapters \
 -H "$(oauth2l header --json path_to_credentials_json --scope admob.readonly)"

Sample response for the AdMob Network ad source with ID 5450213213286189855:

  {

Create an ad unit mapping.

Replace YYYYYYYYYY with your ad unit ID fragment. The ad unit ID fragment is the last 10 digits of your ad unit ID which follows the format "ca-app-pub-XXXXXXXXXXXXXXXX/YYYYYYYYYY". See instructions to find your ad unit ID.

curl --http1.0 -X POST \
 https://admob.googleapis.com/v1beta/accounts/pub-XXXXXXXXXXXXXXXX/adUnits/YYYYYYYYYY/adUnitMappings \
 -H "$(oauth2l header --json path_to_credentials_json --scope admob.monetization)" \
 -H "Content-Type: application/json" --data @- << EOF
{
   "name": "InMobi ad unit mapping",

   "adUnitConfigurations": {
     "174": "inMobiAccountId",
     "176": "inMobiPlacementId"
