Data ingestion from Google Ad Manager transfers

When you transfer data from Google Ad Manager into BigQuery, the data is loaded into BigQuery tables that are partitioned by date. The table partition that the data is loaded into corresponds to the date from the data source. If you schedule multiple transfers for the same date, BigQuery Data Transfer Service overwrites the partition for that specific date with the latest data. Multiple transfers in the same day or running backfills don't result in duplicate data, and partitions for other dates are not affected.

Refresh windows

A refresh window is the number of days that a data transfer retrieves data when a data transfer occurs. For example, if the refresh window is three days and a daily transfer occurs, the BigQuery Data Transfer Service retrieves all data from your source table from the past three days. In this example, when a daily transfer occurs, the BigQuery Data Transfer Service creates a new BigQuery destination table partition with a copy of your source table data from the current day, then automatically triggers backfill runs to update the BigQuery destination table partitions with your source table data from the past two days. The automatically triggered backfill runs will either overwrite or incrementally update your BigQuery destination table, depending on whether or not incremental updates are supported in the BigQuery Data Transfer Service connector.

When you run a data transfer for the first time, the data transfer retrieves all source data available within the refresh window. For example, if the refresh window is three days and you run the data transfer for the first time, the BigQuery Data Transfer Service retrieves all source data within three days.

Refresh windows are mapped to the TransferConfig.data_refresh_window_days API field.

To retrieve data outside the refresh window, such as historical data, or to recover data from any transfer outages or gaps, you can initiate or schedule a backfill run.

Incremental updates

Tables that are created from Google Ad Manager Data Transfer (Google Ad Manager DT) files can be updated incrementally. Google Ad Manager adds the Google Ad Manager DT files into the Cloud Storage bucket. A transfer run then incrementally loads the new Google Ad Manager DT files from the Cloud Storage bucket into the BigQuery table without reloading files that have already been transferred to the BigQuery table.

For example: Google Ad Manager adds file1 into the bucket at 1:00 AM and file2 at 2:00 AM. A transfer run begins at 3:30 AM and loads file1 and file2 to BigQuery. Google Ad Manager then adds file3 at 5:00 AM and file4 at 6:00 AM. A second transfer run begins at 7:30AM and appends file3 and file4 into BigQuery, instead of overwriting the table by loading all four files.

Before you begin

Before you create a Google Ad Manager data transfer:

Verify that you have completed all actions required to enable the BigQuery Data Transfer Service.
Create a BigQuery dataset to store the Google Ad Manager data.
Ensure that your organization has access to Google Ad Manager Data Transfer (Google Ad Manager DT) files. These files are delivered by the Google Ad Manager team to a Cloud Storage bucket. To gain access to Google Ad Manager DT files, review Ad Manager Data Transfer reports. Additional charges from the Google Ad Manager team might apply.

After completing this step, you will receive a Cloud Storage bucket similar to the following:
```
    gdfp-12345678
  
```
The Google Cloud team does NOT have the ability to generate or grant access to Google Ad Manager DT files on your behalf. Contact, Google Ad Manager support, for access to Google Ad Manager DT files.
Enable API access to your Google Ad Manager network.
If you intend to set up data transfer notifications, you must have pubsub.topics.setIamPolicy permissions for Pub/Sub. Pub/Sub permissions are not required if you just set up email notifications. For more information, see BigQuery Data Transfer Service run notifications.

Required permissions

BigQuery: Ensure that the person creating the data transfer has the following permissions in BigQuery:
- bigquery.transfers.update permissions to create the data transfer
- Both bigquery.datasets.get and bigquery.datasets.update permissions on the target dataset
The bigquery.admin predefined IAM role includes bigquery.transfers.update, bigquery.datasets.update and bigquery.datasets.get permissions. For more information on IAM roles in BigQuery Data Transfer Service, see Access control.
Google Ad Manager: Read access to the Google Ad Manager DT files stored in Cloud Storage. Permissions for Google Ad Manager DT files are managed by the Google Ad Manager team. In addition to the Google Ad Manager DT files, the person creating the data transfer must be added to the Google Ad Manager network, with read access to all the entities needed to create the various match tables (line item, order, ad unit, etc.). This can be accomplished by adding the Ad Manager user who authenticated the data transfer to the All Entities team in Ad Manager.

Set up a Google Ad Manager transfer

Setting up a BigQuery data transfer for Google Ad Manager requires a:

Cloud Storage bucket: The Cloud Storage bucket URI for your Google Ad Manager DT files as described in Before you begin. The bucket name should look like the following:
```
gdfp-12345678
```
Network Code: You'll find the Google Ad Manager network code in the URL when you are logged into your network. For example, in the URL https://admanager.google.com/2032576#delivery, 2032576 is your network code. For more information, see Get started with Google Ad Manager.

To create a BigQuery Data Transfer Service data transfer for Google Ad Manager:

Console

Go to the Data transfers page in the Google Cloud console.

Go to Data transfers
Click Create a transfer.
On the Create Transfer page:
- In the Source type section, for Source, choose Google Ad Manager (formerly DFP).
- In the Transfer config name section, for Display name, enter a name for the data transfer such as My Transfer. The transfer name can be any value that lets you identify the transfer if you need to modify it later.
- In the Destination settings section, for Dataset, choose the dataset that you created to store your data.
- In the Data source details section:
  - For Cloud Storage bucket, enter the name of the Cloud Storage bucket that stores your data transfer files. When you enter the bucket name, don't include gs://.
  - For Network code, enter your network code.
- In the Service account menu, select a service account from the service accounts associated with your Google Cloud project. You can associate a service account with your transfer instead of using your user credentials. For more information about using service accounts with data transfers, see Use service accounts.
  
  If you signed in with a federated identity, then a service account is required to create a transfer. If you signed in with a Google Account, then a service account for the transfer is optional. The service account must have the required permissions.
- (Optional) In the Notification options section:
  - Click the toggle to enable email notifications. When you enable this option, the transfer administrator receives an email notification when a transfer run fails.
  - Click the toggle to enable Pub/Sub run notifications. For Select a Cloud Pub/Sub topic, choose your topic name or click Create a topic. This option configures Pub/Sub run notifications for your transfer.
Click Save.

bq

Enter the bq mk command and supply the transfer creation flag — --transfer_config. The following flags are also required:

--data_source
--target_dataset
--display_name
--params

Optional flags:

--service_account_name - Specifies a service account to use for Google Ad Manager transfer authentication instead of your user account.

bq mk --transfer_config \
--project_id=project_id \
--target_dataset=dataset \
--display_name=name \
--params='parameters' \
--data_source=data_source \
--service_account_name=service_account_name

Where:

project_id is your project ID.
dataset is the target dataset for the transfer configuration.
name is the display name for the data transfer configuration. The transfer name can be any value that lets you identify the data transfer if you need to modify it later.
parameters contains the parameters for the created transfer configuration in JSON format. For example: --params='{"param":"param_value"}'. For Google Ad Manager, you must supply the bucket and network_code, parameters. bucket is the Cloud Storage bucket that contains your Google Ad Manager DT files. network_code is your network code.
data_source is the data source — dfp_dt (Google Ad Manager).
service_account_name is the service account name used to authenticate your data transfer. The service account should be owned by the same project_id used to create the transfer and it should have all of the required permissions.

You can also supply the --project_id flag to specify a particular project. If --project_id isn't specified, the default project is used.

For example, the following command creates a Google Ad Manager data transfer named My Transfer using network code 12345678, Cloud Storage bucket gdfp-12345678, and target dataset mydataset. The data transfer is created in the default project:

bq mk --transfer_config \
--target_dataset=mydataset \
--display_name='My Transfer' \
--params='{"bucket": "gdfp-12345678","network_code": "12345678"}' \
--data_source=dfp_dt

After running the command, you receive a message like the following:

[URL omitted] Please copy and paste the above URL into your web browser and follow the instructions to retrieve an authentication code.

Follow the instructions and paste the authentication code on the command line.

API

Use the projects.locations.transferConfigs.create method and supply an instance of the TransferConfig resource.

Troubleshoot Google Ad Manager transfer setup

If you are having issues setting up your data transfer, see Google Ad Manager transfer issues in Troubleshooting transfer configurations.

Query your data

When your data is transferred to BigQuery, the data is written to ingestion-time partitioned tables. For more information, see Introduction to partitioned tables.

If you query your tables directly instead of using the auto-generated views, you must use the _PARTITIONTIME pseudocolumn in your query. For more information, see Querying partitioned tables.

Google Ad Manager sample queries

You can use the following Google Ad Manager sample queries to analyze your transferred data. You can also use the queries in a visualization tool such as Looker Studio. These queries are provided to help you get started on querying your Google Ad Manager data with BigQuery. For additional questions on what you can do with these reports, contact your Google Ad Manager technical representative.

In each of the following queries, replace variables like dataset with your values. For example, replace network_code with your Google Ad Manager network code.

Impressions and unique users by city

The following SQL sample query analyzes the number of impressions and unique users by city over the past 30 days.

# START_DATE = DATE_ADD(CURRENT_DATE(), INTERVAL -31 DAY)
