Bulk Service Manager

Take advantage of the Bulk service to efficiently manage ad groups and ads for all campaigns in an account. The Bing Ads .NET, Java, and Python SDKs provide classes to accelerate productivity for downloading and uploading bulk records. For example the BulkServiceManager will submit your download request to the Bulk service, poll the service until completed, and download the file to your local directory. The BulkServiceManager also handles common request header fields for you, allowing to specify the Authentication, CustomerId, AccountId, and DeveloperToken properties in the AuthorizationData object once for each service. For more information, see Using AuthorizationData and the Bulk Requests code example.

Note

The BulkServiceManager is only available with the Bing Ads .NET, Java, and Python SDKs. Whether or not you use an SDK, you can use the Bulk service directly. For more information, see Bulk Download and Upload.

Bulk File Reader and Writer

You do not need to implement your own file parser to read and write the Bulk file. You can use BulkFileReader and BulkFileWriter objects to read and write BulkEntity derived classes.

Note

The BulkServiceManager uses a BulkFileReader and BulkFileWriter in the background when you upload and download entities instead of files. Temporary files are used in the background. For more details, see Working Directory and BulkServiceManager.

For example, let's say that you want to write the following Expanded Text Ad record to a bulk file.

Type,Status,Id,Parent Id,Campaign,Ad Group,Client Id,Modified Time,Title,Text,Text Part 2,Display Url,Destination Url,Promotion,Device Preference,Ad Format Preference,Name,App Platform,App Id,Final Url,Mobile Final Url,Tracking Template,Custom Parameter,Title Part 1,Title Part 2,Title Part 3,Path 1,Path 2
Format Version,,,,,,,,,,,,,,,6.0,,,,,,,,,,,
Expanded Text Ad,Active,,-1111,ParentCampaignNameGoesHere,AdGroupNameGoesHere,ClientIdGoesHere,,,Find New Customers & Increase Sales!,Start Advertising on Contoso Today.,,,,,False,,,,https://www.contoso.com/womenshoesale,https://mobile.contoso.com/womenshoesale,,{_promoCode}=PROMO1; {_season}=summer,Contoso,Quick & Easy Setup,Seemless Integration,seattle,shoe sale

First, create the BulkExpandedTextAd object as shown below in Bulk and Campaign Management Entity Map. Then you can write the BulkExpandedTextAd to a file with BulkFileWriter as shown here.

var bulkFileWriter = new BulkFileWriter(
    filePath: FileDirectory + UploadFileName
);
bulkFileWriter.WriteEntity(bulkExpandedTextAd);
bulkFileWriter.Dispose();

BulkFileWriter bulkFileWriter = new BulkFileWriter(
    new File(FileDirectory + UploadFileName)
);
bulkFileWriter.writeEntity(bulkExpandedTextAd);
bulkFileWriter.close();

bulk_file_writer=BulkFileWriter(
    file_path=FILE_DIRECTORY+UPLOAD_FILE_NAME
)
bulk_file_writer.write_entity(bulk_expanded_text_ad)
bulk_file_writer.close()

Here is an example of reading the Bulk upload results file from a local directory with BulkFileReader. You can read a bulk file with the BulkFileReader, whether full download, partial download, or upload results.

var bulkFileReader = new BulkFileReader(
    filePath: bulkFilePath, // Path to the Bulk file
    resultFileType: ResultFileType.Upload, // FullDownload, PartialDownload, or Upload
    fileFormat: DownloadFileType.Csv // Csv or Tsv
);
var resultEntities = bulkFileReader.ReadEntities().ToList();
var expandedTextAdResults = resultEntities.OfType<BulkExpandedTextAd>().ToList();
OutputBulkExpandedTextAds(expandedTextAdResults);
bulkFileReader.Dispose();

BulkFileReader bulkFileReader = new BulkFileReader(
    bulkFilePath, // Path to the Bulk file
    ResultFileType.UPLOAD, // FULL_DOWNLOAD, PARTIAL_DOWNLOAD, or UPLOAD
    DownloadFileType.CSV  // Csv or Tsv
);
BulkEntityIterable resultEntities = bulkFileReader.getEntities();
for (BulkEntity entity : resultEntities) {
    if (entity instanceof BulkExpandedTextAd) {
        outputBulkBulkExpandedTextAds(Arrays.asList((BulkExpandedTextAd) entity));
    }
}
resultEntities.close();
bulkFileReader.close();

def read_entities_from_bulk_file(file_path, result_file_type, file_type):
    with BulkFileReader(file_path=file_path, result_file_type=result_file_type, file_type=file_type) as reader:
        for entity in reader:
            yield entity

def main():
    result_entities=[]
    entities_generator=read_entities_from_bulk_file(
        file_path=bulk_file_path, # Path to the Bulk file
        result_file_type=ResultFileType.upload, # full_download, partial_download, or upload
        file_type='Csv'  # Csv or Tsv
    )
    for entity in entities_generator:
        result_entities.append(entity)
    for entity in download_entities:
        if isinstance(entity, BulkExpandedTextAd):
            output_bulk_expanded_text_ads([entity])

Bulk and Campaign Management Entity Map

All objects read from and written to Bulk files via BulkServiceManager, BulkFileReader, BulkFileWriter derive from the BulkEntity base class e.g., BulkCampaign, BulkAdGroup, and BulkExpandedTextAd. Wherever possible the bulk objects leverage Campaign Management objects and value sets e.g., the following BulkExpandedTextAd contains the Campaign Management API ExpandedTextAd object.

var uploadEntities = new List<BulkEntity>();

// Map properties in the Bulk file to the BulkExpandedTextAd
var bulkExpandedTextAd = new BulkExpandedTextAd

    // 'Parent Id' column header in the Bulk file
    AdGroupId = adGroupIdKey,
    // 'Ad Group' column header in the Bulk file
    AdGroupName = "AdGroupNameGoesHere",
    // 'Campaign' column header in the Bulk file
    CampaignName = "ParentCampaignNameGoesHere",
    // 'Client Id' column header in the Bulk file
    ClientId = "ClientIdGoesHere",

    // Map properties in the Bulk file to the 
    // ExpandedTextAd object of the Campaign Management service.
    ExpandedTextAd = new ExpandedTextAd
    {
        // 'Ad Format Preference' column header in the Bulk file
        AdFormatPreference = "All",

Update with delete_value

To remove an existing setting, you should not write an empty string ("") to the Bulk file because such strings are ignored by the Bulk service. Use the reserved "delete_value" string to delete or reset the value of an optional field. If you use the reserved "delete_value" string in an optional field, the previous setting will be deleted. For example if you set the Custom Parameter field of the Expanded Text Ad record to "delete_value", all previous custom parameters will be deleted from the expanded text ad. Likewise if you set the Tracking Template field of the Expanded Text Ad record to "delete_value", the previous tracking template will be deleted from the expanded text ad. For more details about "delete_value" see Bulk File Schema - Update with delete_value.

The BulkFileWriter automatically writes "delete_value" where applicable. Because the SDK maps Campaign Management API objects to the contents of a Bulk file, you cannot explicitly set the "delete_value" string for properties with other data types. In those cases you can use the same syntax that you would use to update the object via the Campaign Management API. In the example below by setting UrlCustomParameters to an empty CustomParameters object, the SDK will write "delete_value" in the Custom Parameter field of the Expanded Text Ad record. Likewise by setting TrackingUrlTemplate to an empty string, the SDK will write "delete_value" in the Tracking Template field of the Expanded Text Ad record. The example syntax within the ExpandedTextAd object is identical to how you would delete previus settings via the UpdateAds service operation via the Campaign Management API.

Important

Do not use empty strings ("") or the "delete_value" syntax when you create a Bulk entity. The reserved "delete_value" string is only applicable for updating Bulk records. Either you should not set the property, or set it to a null equivalent.

var bulkExpandedTextAd = new BulkExpandedTextAd
{
    AdGroupId = adGroupIdKey,
    ExpandedTextAd = new ExpandedTextAd
    {
        Id = expandedTextAdIdKey,
        TrackingUrlTemplate = "",
        UrlCustomParameters = new CustomParameters { }
    },
};

BulkExpandedTextAd bulkExpandedTextAd = new BulkExpandedTextAd();
bulkExpandedTextAd.setAdGroupId(expandedTextAdIdKey);
ExpandedTextAd expandedTextAd = new ExpandedTextAd();
expandedTextAd.setId(adIdKey);
expandedTextAd.setTrackingUrlTemplate("");       
CustomParameters customParameters = new CustomParameters();

bulkExpandedTextAd.setExpandedTextAd(expandedTextAd);

Download and Upload

The BulkServiceManager supports flexible bulk download and upload workflows.

You can create a download or upload request and the BulkServiceManager will submit your download request to the Bulk service, poll the service until completed, and download the file to your local directory. For example, see Background Completion with BulkServiceManager.
You can submit a download or upload request and then poll until the result file is ready to download. For example, see Submit and Download with BulkServiceManager.
If for any reason you have to resume from a previous application state, you can use an existing download or upload request identifier and use it to download the result file. For example, see Download Results with BulkServiceManager.

Whether you download and upload entities in memory or read and write them in a file yourself, the BulkServiceManager reads and writes to a temporary file.

Background Completion with BulkServiceManager

You can create a download or upload request and the BulkServiceManager will submit your download request to the Bulk service, poll the service until completed, and download the file to your local directory.

Download Results with BulkServiceManager

If for any reason you have to resume from a previous application state, you can use an existing download or upload request identifier and use it to download the result file. Track the result to ensure that the download status is completed.

public async Task RunAsync(AuthorizationData authorizationData)
{
    var bulkServiceManager = new BulkServiceManager(authorizationData);

    var progress = new Progress<BulkOperationProgressInfo>(x =>
        Console.WriteLine(String.Format("{0} % Complete", x.PercentComplete.ToString(CultureInfo.InvariantCulture))));

    // You may optionally cancel the TrackAsync operation after a specified time interval. 
    var tokenSource = new CancellationTokenSource();
    tokenSource.CancelAfter(3600000);

    var bulkDownloadOperation = new BulkDownloadOperation(requestId, authorizationData);

    // Use TrackAsync to indicate that the application should wait to ensure that 
    // the download status is completed.
    var bulkOperationStatus = await bulkDownloadOperation.TrackAsync(null, tokenSource.Token);

    var resultFilePath = await bulkDownloadOperation.DownloadResultFileAsync(
        FileDirectory,
        ResultFileName,
        decompress: true,
        overwrite: true  // Set this value true if you want to overwrite the same file.
    );   

    Console.WriteLine(String.Format("Download result file: {0}", resultFilePath));
    Console.WriteLine(String.Format("Status: {0}", bulkOperationStatus.Status));
    Console.WriteLine(String.Format("TrackingId: {0}\n", bulkOperationStatus.TrackingId));
}

Progress<BulkOperationProgressInfo> progress = new Progress<BulkOperationProgressInfo>() {
    @Override
    public void report(BulkOperationProgressInfo value) {
        System.out.println(value.getPercentComplete() + "% Complete\n");
    }
};

java.lang.String requestId = RequestIdGoesHere;

BulkDownloadOperation bulkDownloadOperation = new BulkDownloadOperation(requestId, authorizationData);

// You may optionally cancel the trackAsync operation after a specified time interval.
BulkOperationStatus<DownloadStatus> downloadStatus = bulkDownloadOperation.trackAsync(
    progress, 
    null
).get(3600000, TimeUnit.MILLISECONDS);

System.out.printf(
    "Download Status:\nPercentComplete: %s\nResultFileUrl: %s\nStatus: %s\n",
    downloadStatus.getPercentComplete(), downloadStatus.getResultFileUrl(), downloadStatus.getStatus()
);

File resultFile = bulkDownloadOperation.downloadResultFileAsync(
    new File(FileDirectory),
    ResultFileName,
    true,    // Set this value to true if you want to decompress the ZIP file
    true,    // Set this value true if you want to overwrite the same file.

Poll and Retry

Poll for download and upload results at reasonable intervals. You know your data better than anyone. For example if you download an account that is well less than one million keywords, consider polling at 5 to 20 second intervals. If the account contains about one million keywords, consider polling at one minute intervals after waiting five minutes. For accounts with about four million keywords, consider polling at one minute intervals after waiting 10 minutes.

The BulkServiceManager automatically polls for the result file in 1000 millisecond intervals for the first five attempts, and that behavior is not configurable. The StatusPollIntervalInMilliseconds property determines the time interval between each polling attempt after the initial five attempts. For an example please see Background Completion above. The default value is 5000, so if you do not set this value the BulkServiceManager will poll in the following sequence of minutes: 1, 2, 3, 4, 5, 10, 15, 20, and so on. If you set this value to 10000, the BulkServiceManager will poll in the following sequence: 1, 2, 3, 4, 5, 15, 25, 35, and so on. The minimum poll interval is 1000, and if you specify a value less than 1000 an exception will be thrown.

The BulkServiceManager will automatically retry upload, download, and polling operations up to the maximum timeout duration that you set. You can set the maximum retry timeout duration. If no timeout is specified, the BulkServiceManager will continue to retry until the server returns a timeout or internal error. Separately, if you are uploading or downloading large files, you should consider setting the UploadHttpTimeout or DownloadHttpTimeout properties.

Working Directory and BulkServiceManager

With the Bing Ads .NET and Java SDKs, you can set the working directory where BulkServiceManager should store temporary bulk files. For example, when you download entities with the Bing Ads .NET SDK, although you will only directly work with BulkEntity objects a bulk file is downloaded to the working directory. Likewise when you upload entities, a temporary file is written to the working directory, and then uploaded to the Bulk service. The system temporary directory will be used if another working directory is not specified.

If you are using a hosted service such as Microsoft Azure you'll want to ensure you do not exceed the temp directory limits. There may be other reasons to use a custom working directory. You can specify a different working directory for each BulkServiceManager instance by setting the WorkingDirectory property. You are also responsible for creating and removing any directories. After you have iterated over the bulk entities you can clean up the files from the working directory.
