Get Started with the API | Display & Video 360

This document explains how to get started writing applications that use the Google DoubleClick Bid Manager API. The API enables developers to manage Queries, retrieve Report metadata, and download and upload LineItems.

DoubleClick Bid Manager API v1 is the latest available and recommended version.

1. Before you start

If you're unfamiliar with Google Display & Video 360 concepts, read the Display & Video 360 Help Center and experiment with the user interface.

2. Prepare for authentication

To get started using DoubleClick Bid Manager API, you need to first use the setup tool, which guides you through creating a project in the Google API Console, enabling the API, and creating credentials.

If you haven't done so already, create your OAuth 2.0 credentials by clicking Create credentials > OAuth client ID. After you've created the credentials, you can see your client ID on the Credentials page. Click the client ID for details, such as client secret, redirect URIs, JavaScript origins address, and email address.

For more information, see Authorize Requests.

3. Call the DoubleClick Bid Manager API

The tabs below provide quickstarts for coding in various languages. All of the code shown is included in the DoubleClick Bid Manager API Examples repo

Java

Here is a basic example that shows how to use the DoubleClick Bid Manager API with Java.

Create an Eclipse maven project

Open the pom.xml and add these dependencies:

<dependencies>
 <dependency>
    <groupId>com.google.apis</groupId>
    <artifactId>google-api-services-doubleclickbidmanager</artifactId>
    <version>v1-rev48-1.22.0</version>
  </dependency>
  <dependency>
    <groupId>com.google.http-client</groupId>
    <artifactId>google-http-client-jackson2</artifactId>
    <version>${project.http.version}</version>
  </dependency>
  <dependency>
    <groupId>com.google.oauth-client</groupId>
    <artifactId>google-oauth-client-jetty</artifactId>
    <version>${project.oauth.version}</version>
  </dependency>
</dependencies>

Load the client secrets file

All calls to the API require authentication; load up the client secrets file you downloaded to create a GoogleClientSecrets object.

GoogleClientSecrets clientSecrets = GoogleClientSecrets.load(
    JSON_FACTORY,
    new InputStreamReader(
        DoubleClickBidManagerFactory.class.getResourceAsStream("/client_secrets.json"),
        UTF_8));

Get authorized credentials

Create a Credential object using the GoogleClientSecrets.

// Set up the authorization code flow.
GoogleAuthorizationCodeFlow flow =
    new GoogleAuthorizationCodeFlow.Builder(HTTP_TRANSPORT, JSON_FACTORY, clientSecrets,
        DoubleClickBidManagerScopes.all()).setDataStoreFactory(dataStoreFactory).build();

// Authorize and persist credential information to the data store.
return new AuthorizationCodeInstalledApp(flow, new LocalServerReceiver()).authorize("user");

Construct a client for the DoubleClick Bid Manager API service

Use the Credential object to create an authenticated DoubleClickBidManager using the Builder pattern:

DoubleClickBidManager bidmanager =
    new DoubleClickBidManager.Builder(HTTP_TRANSPORT, JSON_FACTORY, setHttpTimeout(credential))
        .setApplicationName(APPLICATION_NAME + "_JavaSamples")
        .build();

Perform operations

After you've instantiated a client to connect to the API, you can begin performing operations. For example, you can make a listqueries request and display all available queries:

// Call the API, getting a list of queries.
ListQueriesResponse queryListResponse = service.queries().listqueries().execute();

// Print them out.
System.out.println("Id\t\tName");
for (Query query : queryListResponse.getQueries()) {
  System.out.format("%s\t%s%n", query.getQueryId(), query.getMetadata().getTitle());
}

Or identify a specific query and download the latest report:

// Retrieve the download URL for the latest report.
GenericUrl reportUrl =
    new GenericUrl(query.getMetadata().getGoogleCloudStoragePathForLatestReport());

// Download the report file.
try (OutputStream output = new FileOutputStream(query.getQueryId() + ".csv")) {
  MediaHttpDownloader downloader = new MediaHttpDownloader(HTTP_TRANSPORT, null);
  downloader.download(reportUrl, output);
}

System.out.println("Download complete.");

Python

Here is a basic example that shows how to use the DoubleClick Bid Manager API with Python.

Download and install the Google API Python Client
Example using pip:
```
pip --upgrade google-api-python-client
```

Get authorized credentials

Use the Client ID and Secret from above to prompt for authorization.

flow = client.flow_from_clientsecrets(
    client_secrets,
    scope=API_SCOPES,
    message=tools.message_if_missing(client_secrets))

# Retrieve credentials from storage.
# If the credentials don't exist or are invalid run through the installed
# client flow. The storage object will ensure that if successful the good
# credentials will get written back to file.
credentials = storage.get()
if credentials is None or credentials.invalid:
  credentials = tools.run_flow(flow, storage, flags)

return credentials

Construct a client for the DoubleClick Bid Manager API service
Create a client for the DoubleClick Bid Manager API passing in the latest version of the API.
```
return discovery.build(API_NAME, API_VERSION, http=http)
```

Perform operations

After you've instantiated a client to connect to the API, you can begin performing operations. For example, you can make a listqueries request and display all available queries:

# Call the API, getting a list of queries.
response = doubleclick_bid_manager.queries().listqueries().execute()

# Print queries out.
print('Id\t\tName')
if 'queries' in response:
  for q in response['queries']:
    print('%s\t%s' % (q['queryId'], q['metadata']['title']))
else:
  print('No queries exist.

Or identify a specific query and download the latest report:

# Grab the report and write contents to a file.
report_url = query['metadata']['googleCloudStoragePathForLatestReport']
output_file = '%s/%s.csv' % (output_dir, query['queryId'])
with open(output_file, 'wb') as output:
  with closing(urlopen(report_url)) as url:
    output.write(url.read())
print('Download complete.

PHP

Here is a basic example that shows how to use the DoubleClick Bid Manager API with PHP.

Download and install the Google API PHP Client
The preferred method is via Composer:
```
composer require google/apiclient:^2.0
```
Once installed, be sure to include the autoloader:
```
require_once '/path/to/your-project/vendor/autoload.php';
```
Create a Google_Client object.
```
$client = new Google_Client();
```

Set up your credentials

All calls to the API require authentication; load up the client secrets file you downloaded and add a scope for your requests.

$client->setApplicationName('DBM API PHP Samples');
$client->addScope('https://www.googleapis.com/auth/doubleclickbidmanager');
$client->setAccessType('offline');

Construct a client for the DoubleClick Bid Manager API service
You can then create your DoubleClickBidManager client using the authorized Google_Client object:
```
$service = new Google_Service_DoubleClickBidManager($client);
```

Perform operations

After you've instantiated a client to connect to the API, you can begin performing operations. For example, you can make a listqueries request and display all available queries:

// Call the API, getting a list of queries.
$result = $this->service->queries->listqueries();
if (isset($result['queries']) && count($result['queries']) > 0) {
  print '<pre>';
  foreach ($result['queries'] as $query) {
    printf('<p>%s %s</p>', $query->queryId, $query->metadata->title);
  }
  print '</pre>';
} else {
  print '<p>No reports found</p>';
}

Or identify a specific query and download the latest report:

// Grab the report.
file_put_contents($query->queryId . '.csv',
    fopen($query->metadata->googleCloudStoragePathForLatestReport,
        'r'));
print '<p>Download complete.</p>';
