Upload creative assets

Creatives hosted by Display & Video 360 are built from Asset objects. An asset is defined by a mediaId or some text content. Use the upload method to upload media for use in assets before creating the creative object.

An asset must have the same parent advertiser as the creative that uses it. To use an asset across advertisers, upload the media file under each advertiser.

Here's how to upload a media asset:

Java

// Provide the parent advertiser ID to upload the media file under.
long advertiserId = advertiser-id;

// Provide the local path to the media file.
String assetPath = asset-path

// Get filename from path
String assetFilename = new File(assetPath).getName();

// Create the asset upload request content
CreateAssetRequest content = new CreateAssetRequest().setFilename(assetFilename);

// Parse filename for appropriate MIME type
FileNameMap filenameMap = URLConnection.getFileNameMap();
String mimeType = filenameMap.getContentTypeFor(assetFilename);
if (mimeType == null) {
  mimeType = "application/octet-stream";
}

// Create input stream for the creative asset.
InputStreamContent assetStream =
    new InputStreamContent(mimeType, new FileInputStream(assetPath));

// Configure the asset upload request.
Assets.Upload assetRequest =
    service.advertisers().assets().upload(advertiserId, content, assetStream);

// Upload the asset.
CreateAssetResponse assetResponse = assetRequest.execute();

// Display the new asset media ID.
System.out.printf("Asset was created with media ID %s.", assetResponse.getAsset().getMediaId());

Python

# Import the object used as the media body for the upload request.
from apiclient.http import MediaFileUpload

# Provide the parent advertiser ID to upload the media file under.
advertiser_id = advertiser-id

# Provide the filename and local path to the media file.
asset_filename = asset-filename
asset_path = asset-path

# Create the request body.
body = {"filename": asset_filename}

# Create the upload object and use a default MIME type if not identified.
media = MediaFileUpload(asset_path)
if not media.mimetype():
    media = MediaFileUpload(asset_path, "application/octet-stream")

# Upload the asset.
upload_response = (
    service.advertisers()
    .assets()
    .upload(advertiserId=advertiser_id, body=body, media_body=media)
    .execute()
)

# Print resulting media ID.
print(
    f'Asset was created with media ID {upload_response["asset"]["mediaId"]}.'
)

PHP

// Configure the asset upload request.
$body = new Google_Service_DisplayVideo_CreateAssetRequest();
$body->setFilename(asset-filename);
$optParams = array(
    'data' => file_get_contents(asset-path),
    'mimeType' => mime_content_type(asset-filename),
    'uploadType' => 'media'
);

// Call the API to upload the creative asset.
try {
    $result = $service->advertisers_assets->upload(
        advertiser-id
        $body,
        $optParams
    );
} catch (\Exception $e) {
    $this->renderError($e);
    return;
}

// Display the new asset media ID.
printf(
    '<p>Asset was created with media ID %s.</p>',
    $result->getAsset()->getMediaId()
);
