Google Campaign Manager 360 Connection Details¶

Introduction¶

Connector Version

This documentation is based on version 23.0.8804 of the connector.

Get Started¶

Google Campaign Manager Version Support

The connector surfaces the reports and fields available through the v2.8 Google Campaign Manager API. The connector exposes all existing reports in your DCM instance as well as a set of generic tables for ad-hoc reporting.

Establish a Connection¶

Connect to Google Campaign Manager¶

Provide the following connection properties before adding the authentication properties.

• ProfileID: Set this to the DoubleClick User Profile ID you want to connect to. This value can be retrieved from the Profiles table. If this is not specified, the first User Profile returned will be used.

Authenticate to Google Campaign Manager¶

The connector supports using user accounts, service accounts and GCP instance accounts for authentication.

The following sections discuss the available authentication schemes for Google Campaign Manager:

• User Accounts (OAuth)
• Service Account (OAuthJWT)
• GCP Instance Account

User Accounts (OAuth)¶

AuthScheme must be set to OAuth in all user account flows.

Desktop Applications¶

provides an embedded OAuth application that simplifies OAuth desktop Authentication. Alternatively, you can create a custom OAuth application. See Creating a Custom OAuth App for information about creating custom applications and reasons for doing so.

For authentication, the only difference between the two methods is that you must set two additional connection properties when using custom OAuth applications.

After setting the following connection properties, you are ready to connect:

• InitiateOAuth: Set this to GETANDREFRESH, which instructs the connector to automatically attempt to get and refresh the OAuth access token.
• OAuthClientId: (custom applications only) Set this to the Client ID in your custom OAuth application settings.
• OAuthClientSecret: (custom applications only) Set this to the Client Secret in the custom OAuth application settings.

When you connect the connector opens the OAuth endpoint in your default browser. Log in and grant permissions to the application. The connector then completes the OAuth process as follows:

• Extracts the access token from the callback URL.
• Obtains a new access token when the old one expires.
• Saves OAuth values in OAuthSettingsLocation that persist across connections.

Web Applications¶

When connecting via a Web application, you need to create and register a custom OAuth application with Google Campaign Manager. You can then use the connector to acquire and manage the OAuth token values. See Creating a Custom OAuth App for more information about custom applications.

Get an OAuth Access Token

Set the following connection properties to obtain the OAuthAccessToken:

• OAuthClientId: Set this to the Client ID in your application settings.
• OAuthClientSecret: Set this to the Client Secret in your application settings.

Then call stored procedures to complete the OAuth exchange:

1. Call the GetOAuthAuthorizationURL stored procedure. Set the CallbackURL input to the Callback URL you specified in your application settings. The stored procedure returns the URL to the OAuth endpoint.
2. Navigate to the URL that the stored procedure returned in Step 1. Log in to the custom OAuth application and authorize the web application. Once authenticated, the browser redirects you to the callback URL.
3. Call the GetOAuthAccessToken stored procedure. Set AuthMode to WEB and the Verifier input to the "code" parameter in the query string of the callback URL.

Once you have obtained the access and refresh tokens, you can connect to data and refresh the OAuth access token either automatically or manually.

Automatic Refresh of the OAuth Access Token

To have the driver automatically refresh the OAuth access token, set the following on the first data connection:

• InitiateOAuth: Set this to REFRESH.
• OAuthClientId: Set this to the Client ID in your application settings.
• OAuthClientSecret: Set this to the Client Secret in your application settings.
• OAuthAccessToken: Set this to the access token returned by GetOAuthAccessToken.
• OAuthRefreshToken: Set this to the refresh token returned by GetOAuthAccessToken.
• OAuthSettingsLocation: Set this to the location where the connector saves the OAuth token values, which persist across connections.

On subsequent data connections, the values for OAuthAccessToken and OAuthRefreshToken are taken from OAuthSettingsLocation.

Manual Refresh of the OAuth Access Token

The only value needed to manually refresh the OAuth access token when connecting to data is the OAuth refresh token.

Use the RefreshOAuthAccessToken stored procedure to manually refresh the OAuthAccessToken after the ExpiresIn parameter value returned by GetOAuthAccessToken has elapsed, then set the following connection properties:

• OAuthClientId: Set this to the Client ID in your application settings.
• OAuthClientSecret: Set this to the Client Secret in your application settings.

Then call RefreshOAuthAccessToken with OAuthRefreshToken set to the OAuth refresh token returned by GetOAuthAccessToken. After the new tokens have been retrieved, open a new connection by setting the OAuthAccessToken property to the value returned by RefreshOAuthAccessToken.

Finally, store the OAuth refresh token so that you can use it to manually refresh the OAuth access token after it has expired.

Headless Machines¶

To configure the driver to use OAuth with a user account on a headless machine, you need to authenticate on another device that has an internet browser.

1. Choose one of two options:
   • Option 1: Obtain the OAuthVerifier value as described in "Obtain and Exchange a Verifier Code" below.
   • Option 2: Install the connector on a machine with an internet browser and transfer the OAuth authentication values after you authenticate through the usual browser-based flow, as described in "Transfer OAuth Settings" below.
2. Then configure the connector to automatically refresh the access token on the headless machine.

Option 1: Obtain and Exchange a Verifier Code

To obtain a verifier code, you must authenticate at the OAuth authorization URL.

Follow the steps below to authenticate from the machine with an internet browser and obtain the OAuthVerifier connection property.

1. Choose one of these options:

   • If you are using the Embedded OAuth Application click Google Campaign Manager OAuth endpoint to open the endpoint in your browser.

   • If you are using a custom OAuth application, create the Authorization URL by setting the following properties:

     • InitiateOAuth: Set to OFF.
     • OAuthClientId: Set to the client ID assigned when you registered your application.
     • OAuthClientSecret: Set to the client secret assigned when you registered your application.

     Then call the GetOAuthAuthorizationURL stored procedure with the appropriate CallbackURL. Open the URL returned by the stored procedure in a browser. 2. Log in and grant permissions to the connector. You are then redirected to the callback URL, which contains the verifier code. 3. Save the value of the verifier code. Later you will set this in the OAuthVerifier connection property.

Next, you need to exchange the OAuth verifier code for OAuth refresh and access tokens. Set the following properties:

On the headless machine, set the following connection properties to obtain the OAuth authentication values:

• InitiateOAuth: Set this to REFRESH.
• OAuthVerifier: Set this to the verifier code.
• OAuthClientId: (custom applications only) Set this to the Client ID in your custom OAuth application settings.
• OAuthClientSecret: (custom applications only) Set this to the Client Secret in the custom OAuth application settings.
• OAuthSettingsLocation: Set this to persist the encrypted OAuth authentication values to the specified location.

After the OAuth settings file is generated, you need to re-set the following properties to connect:

• InitiateOAuth: Set this to REFRESH.
• OAuthClientId: (custom applications only) Set this to the client ID assigned when you registered your application.
• OAuthClientSecret: (custom applications only) Set this to the client secret assigned when you registered your application.
• OAuthSettingsLocation: Set this to the location containing the encrypted OAuth authentication values. Make sure this location gives read and write permissions to the connector to enable the automatic refreshing of the access token.

Option 2: Transfer OAuth Settings

Prior to connecting on a headless machine, you need to create and install a connection with the driver on a device that supports an internet browser. Set the connection properties as described in "Desktop Applications" above.

After completing the instructions in "Desktop Applications", the resulting authentication values are encrypted and written to the location specified by OAuthSettingsLocation. The default filename is OAuthSettings.txt.

Once you have successfully tested the connection, copy the OAuth settings file to your headless machine.

On the headless machine, set the following connection properties to connect to data:

• InitiateOAuth: Set this to REFRESH.
• OAuthClientId: (custom applications only) Set this to the client ID assigned when you registered your application.
• OAuthClientSecret: (custom applications only) Set this to the client secret assigned when you registered your application.
• OAuthSettingsLocation: Set this to the location of your OAuth settings file. Make sure this location gives read and write permissions to the connector to enable the automatic refreshing of the access token.

Service Accounts (OAuthJWT)¶

To authenticate using a service account, you must create a new service account and have a copy of the accounts certificate. If you do not already have a service account, you can create one by following the procedure in Creating a Custom OAuth App.

For a JSON file, set these properties:

• AuthScheme: Set this to OAuthJWT.
• InitiateOAuth: Set this to GETANDREFRESH.
• OAuthJWTCertType: Set this to GOOGLEJSON.
• OAuthJWTCert: Set this to the path to the .json file provided by Google.
• OAuthJWTSubject: (optional) Only set this value if the service account is part of a GSuite domain and you want to enable delegation. The value of this property should be the email address of the user whose data you want to access.

For a PFX file, set these properties instead:

• AuthScheme: Set this to OAuthJWT.
• InitiateOAuth: Set this to GETANDREFRESH.
• OAuthJWTCertType: Set this to PFXFILE.
• OAuthJWTCert: Set this to the path to the .pfx file provided by Google.
• OAuthJWTCertPassword: (optional) Set this to the .pfx file password. In most cases you must provide this since Google encrypts PFX certificates.
• OAuthJWTCertSubject: (optional) Set this only if you are using a OAuthJWTCertType which stores multiple certificates. Should not be set for PFX certificates generated by Google.
• OAuthJWTIssuer: Set this to the email address of the service account. This address will usually include the domain iam.gserviceaccount.com.
• OAuthJWTSubject: (optional) Only set this value if the service account is part of a GSuite domain and you want to enable delegation. The value of this property should be the email address of the user whose data you want to access.

GCP Instance Accounts¶

When running on a GCP virtual machine, the connector can authenticate using a service account tied to the virtual machine. To use this mode, set AuthScheme to GCPInstanceAccount.

Create a Custom OAuth App¶

When to Create a Custom OAuth App¶

embeds OAuth Application Credentials with branding that can be used when connecting via either a Desktop Application or from a Headless Machine. Creating a custom OAuth application is, however, required when using a web application.

For service accounts, you must always create a custom OAuth application.

You may choose to create your own OAuth Application Credentials when you want to

• control branding of the Authentication Dialog
• control the redirect URI that the application redirects the user to after the user authenticates
• customize the permissions that you are requesting from the user

User Accounts¶

Create an OAuth App for User Account Authentication¶

Follow the procedure below to register an app and obtain the OAuthClientId and OAuthClientSecret.

Desktop Applications¶

1. Log into the Google API Console and open a project.
2. Select the API Manager from the main menu.
3. Select Credentials > Create Credentials > OAuth Client Id. Then click Other.
4. Select Library > DCM/DFA Reporting And Trafficking API > Enable API.

Create an OAuth App for Service Account Authentication¶

To obtain the necessary authentication properties, follow the steps below to create an OAuth application and generate a private key:

1. Log into the Google API Console and open a project.
2. Select the API Manager from the main menu.
3. Select Create Credentials > Service Account Key.
4. In the Service Account menu, select New Service Account or choose an existing service account.
5. If you are creating a new service account, select one or more roles. You can assign primitive roles at the project level in IAM and Admin; other roles enable you to further customize access to Google APIs.
6. In Key Type, select the P12 key type.
7. Create the app to download the key pair. The private key's password is displayed: Set this in OAuthJWTCertPassword.
8. In the service accounts section, click Manage Service Accounts and set OAuthJWTIssuer to the email address displayed in the service account Id field.

Retrieve DoubleClick Campaign Manager data¶

DoubleClick Campaign Manager data is organized into various metrics (Clicks, CostPerClick, Impressions, etc.), which can be queried over various dimensions (Country, Month, etc.). Auto-discovering all existing reports for your DCM account is extremely expensive. To work around this, the connector exposes five generic tables, one for each type of report, which allow for ad-hoc reporting as well as running your existing reports. There is also the option to create custom schema files for your existing reports so they can be queried as their own tables. These sections will discuss the different strategies for querying your DCM data with the connector.

Built-In Reporting Tables¶

There are five built-in tables in the driver: CrossDimensionReachReport, FloodlightReport, PathToConversionReport, ReachReport, and StandardReport. These generic tables include all possible dimensions and metrics for the given report type but not all combinations of dimensions or metrics are valid in DCM. Therefore, 'SELECT *' queries to these tables are not permitted normally. Instead, you have several options of pulling data from these tables:

1. Ad-hoc reporting is available by running a query selecting any valid combination of dimensions or metrics from the table. For example:

   SELECT Campaign, CampaignId, Impressions, Clicks, ClickRate, TotalConversions FROM StandardReport
   

   This query involves a multi-step process. First, the report definition is created in DCM and the processing is started. Note that DCM reports can take a very long time to process especially if you have a large volume of data. Once the processing is finished, the report is downloaded and output by the connector. Finally, the report definition is deleted from DCM.

2. You can supply a ReportID in the filter for the query to run an existing report. This query allows for 'SELECT *' but note that only the fields that are actually included in the report will be populated with data with the rest returning NULL. For example:

   SELECT * FROM StandardReport WHERE ReportID='123456789'
   

   The report is executed in real time so note that DCM reports can take a very long time to process especially if you have a large volume of data. The report definition is not deleted in this case.

3. You can supply both a ReportID and a FileID in the filter to download a previously run report. This query allows for 'SELECT *' but note that only the fields that are actually included in the report will be populated with data with the rest returning NULL. For example:

   SELECT * FROM StandardReport WHERE ReportID='123456789' AND FileID='987654321'
   

   Since the report has already been executed in this case, results will return immediately. The RunReport and CheckReportStatus stored procedures along with this method of querying can be used for asynchronous processing of the report in your application.

Exist DCM Reports¶

The connector also offers the CreateCustomSchema stored procedure for creating new table definitions for your existing reports in DCM. The stored procedure takes a table name, the report ID, and an output folder as inputs. Calling it will create a new schema file that you can query like any other table. You will need to set the Location connection property to the folder containing the new script files in order to access them after they are created. For example:

EXEC CreateCustomSchema TableName='MyCustomReport', ReportID='123456789', OutputFolder='C:\Users\Administrator\Desktop'

Important Notes¶

Configuration Files and Their Paths¶

• All references to adding configuration files and their paths refer to files and locations on the Harmony Agent where the connector is installed. These paths are to be adjusted as appropriate depending on the agent and the operating system. If multiple agents are used in an agent group, identical files will be required on each agent.

Advanced Features¶

This section details a selection of advanced features of the Google Campaign Manager connector.

User Defined Views

The connector allows you to define virtual tables, called user defined views, whose contents are decided by a pre-configured query. These views are useful when you cannot directly control queries being issued to the drivers. See User Defined Views for an overview of creating and configuring custom views.

SSL Configuration

Use SSL Configuration to adjust how connector handles TLS/SSL certificate negotiations. You can choose from various certificate formats; see the SSLServerCert property under "Connection String Options" for more information.

Proxy

To configure the connector using Private Agent proxy settings, select the Use Proxy Settings checkbox on the connection configuration screen.

Query Processing

The connector offloads as much of the SELECT statement processing as possible to Google Campaign Manager and then processes the rest of the query in memory (client-side).

User Defined Views¶

The Jitterbit Connector for Google Campaign Manager allows you to define a virtual table whose contents are decided by a pre-configured query. These are called User Defined Views, which are useful in situations where you cannot directly control the query being issued to the driver, e.g. when using the driver from Jitterbit. The User Defined Views can be used to define predicates that are always applied. If you specify additional predicates in the query to the view, they are combined with the query already defined as part of the view.

There are two ways to create user defined views:

• Create a JSON-formatted configuration file defining the views you want.
• DDL statements.

Define Views Using a Configuration File¶

User Defined Views are defined in a JSON-formatted configuration file called UserDefinedViews.json. The connector automatically detects the views specified in this file.

You can also have multiple view definitions and control them using the UserDefinedViews connection property. When you use this property, only the specified views are seen by the connector.

This User Defined View configuration file is formatted as follows:

• Each root element defines the name of a view.
• Each root element contains a child element, called query, which contains the custom SQL query for the view.

For example:

{
    "MyView": {
        "query": "SELECT * FROM CampaignPerformance WHERE MyColumn = 'value'"
    },
    "MyView2": {
        "query": "SELECT * FROM MyTable WHERE Id IN (1,2,3)"
    }
}

Use the UserDefinedViews connection property to specify the location of your JSON configuration file. For example:

"UserDefinedViews", "C:\Users\yourusername\Desktop\tmp\UserDefinedViews.json"

Define Views Using DDL Statements¶

The connector is also capable of creating and altering the schema via DDL Statements such as CREATE LOCAL VIEW, ALTER LOCAL VIEW, and DROP LOCAL VIEW.

Create a View¶

To create a new view using DDL statements, provide the view name and query as follows:

CREATE LOCAL VIEW [MyViewName] AS SELECT * FROM Customers LIMIT 20;

If no JSON file exists, the above code creates one. The view is then created in the JSON configuration file and is now discoverable. The JSON file location is specified by the UserDefinedViews connection property.

Alter a View¶

To alter an existing view, provide the name of an existing view alongside the new query you would like to use instead:

ALTER LOCAL VIEW [MyViewName] AS SELECT * FROM Customers WHERE TimeModified > '3/1/2020';

The view is then updated in the JSON configuration file.

Drop a View¶

To drop an existing view, provide the name of an existing schema alongside the new query you would like to use instead.

DROP LOCAL VIEW [MyViewName]

This removes the view from the JSON configuration file. It can no longer be queried.

Schema for User Defined Views¶

User Defined Views are exposed in the UserViews schema by default. This is done to avoid the view's name clashing with an actual entity in the data model. You can change the name of the schema used for UserViews by setting the UserViewsSchemaName property.

Work with User Defined Views¶

For example, a SQL statement with a User Defined View called UserViews.RCustomers only lists customers in Raleigh:

SELECT * FROM Customers WHERE City = 'Raleigh';

An example of a query to the driver:

SELECT * FROM UserViews.RCustomers WHERE Status = 'Active';

Resulting in the effective query to the source:

SELECT * FROM Customers WHERE City = 'Raleigh' AND Status = 'Active';

That is a very simple example of a query to a User Defined View that is effectively a combination of the view query and the view definition. It is possible to compose these queries in much more complex patterns. All SQL operations are allowed in both queries and are combined when appropriate.

SSL Configuration¶

Customize the SSL Configuration¶

By default, the connector attempts to negotiate SSL/TLS by checking the server's certificate against the system's trusted certificate store.

To specify another certificate, see the SSLServerCert property for the available formats to do so.

Data Model¶

The Jitterbit Connector for Google Campaign Manager models Google Campaign Manager entities in relational Tables, Views, and Stored Procedures. The provided tables will give you an overview of your account information and the reports available for DoubleClick Campaign Manager queries.

API limitations and requirements are documented in this section.

Create Additional Schemas

The CreateCustomSchema stored procedure can be used to easily generate new schema files for a given report. This procedure takes the TableName and a report ID and builds a schema file that can be read by the connector.

If the Location connection property is set, the file will be output to that folder. Otherwise, the OutputFolder input can be used to specify an output folder. To begin querying these new files, simply set the Location connection property to the folder containing these new schema files.

Views

Views are tables that cannot be modified. Typically, data that are read-only and cannot be updated are shown as views.

Stored Procedures

Stored Procedures are function-like interfaces to the data source. They can be used to search, update, and modify information in the data source.

Views¶

Views are similar to tables in the way that data is represented; however, views are read-only.

Queries can be executed against a view as if it were a normal table.
