JDBC Driver for Facebook Ads

Build 23.0.8839

Establishing a Connection

Creating a JDBC Data Source

You can create a JDBC data source to connect from your Java application. Creating a JDBC data source based on the CData JDBC Driver for Facebook Ads consists of three basic steps:

  • Add the driver JAR file to the classpath. The JAR file is located in the lib subfolder of the installation directory. Note that the .lic file must be located in the same folder as the JAR file.
  • Provide the driver class. For example:
    cdata.jdbc.facebookads.FacebookAdsDriver
  • Provide the JDBC URL. For example:
    jdbc:facebookads:InitiateOAuth=GETANDREFRESH;
    
    or
    
    jdbc:cdata:facebookads:InitiateOAuth=GETANDREFRESH;

    The second format above can be used whenever there is a conflict in your application between drivers using the same URL format to ensure you are using the CData driver. The URL must start with either "jdbc:facebookads:" or "jdbc:cdata:facebookads:" and can include any of the connection properties in name-value pairs separated with semicolons.

Connecting to Facebook Ads

The following are optional connection properties:

  • Target: Some Facebook tables can be filtered by a target. For example, to retrieve comments on a video, specify the Id of the video as the target. This property enables you to restrict the results of all queries in the connection to records that match the specified target. You can also specify this restriction per query with the Target column.
  • AggregateFormat: The driver returns some columns as a string aggregate. For example, the available likes data for an entity is returned in aggregate. By default, the driver returns aggregate columns in JSON. You can also return aggregates in XML.
  • RetryLevel: Use this property to control automatic query retry for specific ad insights queries and errors.

Authenticating to Facebook Ads

Facebook Ads uses the OAuth standard to authenticate users.

OAuth

In all OAuth flows, you must set AuthScheme to OAuth. The sections below assume that you have done so.

Desktop Applications

CData provides an embedded OAuth application that simplifies OAuth desktop Authentication. Alternatively, you can create a custom OAuth application. See Creating a Custom OAuth Application 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. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
  • OAuthClientId: (custom applications only) Set this to the client Id in your application settings.
  • OAuthClientSecret: (custom applications only) Set this to the client secret in your application settings.
  • CallbackURL: Set this to the Redirect URL in your application settings.
  • Scope (optional): Set this if you need to customizie the permissions that the driver requests.
  • AuthenticateAsPage (optional): Set this to a page name or Id to make requests as a page. The page must be managed by the authenticated user.

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

  1. Extracts the access token from the callback URL.
  2. Obtains a new access token when the old one expires.
  3. Saves OAuth values in OAuthSettingsLocation. These values persist across connections.

Web Applications

When connecting via a Web application, you need to create and register a custom OAuth application with Facebook Ads. See Creating a Custom OAuth App for more information about custom applications. You can then use the driver to get and manage the OAuth token values.

Get an OAuth Access Token

Set the following connection properties to obtain the OAuthAccessToken:

  • AuthScheme: Set this to AzureAD.
  • OAuthClientId: Set this to the client Id in your application settings.
  • OAuthClientSecret: Set this to the client secret in your application settings
  • Scope (optional): Set this if you need to customizie the permissions that the driver requests.
  • AuthenticateAsPage (optional): Set this to a page name or Id to make requests as a page. The page must be managed by the authenticated user.

Then call stored procedures to complete the OAuth exchange:

  1. Call the GetOAuthAuthorizationURL stored procedure. Set the AuthMode input to WEB and set the CallbackURL input to the Redirect URI you specified in your app settings. If necessary, set the "Permissions" parameter to request custom permissions.
  2. Open the URL, log in, and authorize the application. You are redirected back to the callback URL.
  3. Call the GetOAuthAccessToken stored procedure. Set the AuthMode input to WEB. Set the Verifier input to the "code" parameter in the query string of the callback URL. If necessary, set the "Permissions" parameter to request custom permissions.

To connect to data, set the OAuthAccessToken connection property to the access token returned by the stored procedure. When the access token expires after ExpiresIn seconds, call GetOAuthAccessToken again to obtain a new access token. [

Headless Machines

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

Creating a custom OAuth app is optional in the headless OAuth flow; if you want to skip creating an app, you can connect with the driver's embedded OAuth credentials. However, you might want to create a custom OAuth app to change the information displayed when users log into Facebook to grant permissions to the driver. For information on how to create a custom OAuth application, see Creating a Custom OAuth App.

  1. Choose one of these two options:
    • Option 1: Obtain the OAuthVerifier value as described in "Obtain and Exchange a Verifier Code", below.
    • Option 2: Install the driver on another machine and transfer the OAuth authentication values after you authenticate through the usual browser-based flow, as described in "Transfer OAuth Settings", below.
  2. Configure the driver to automatically refresh the access token from 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. If you are using the Embedded OAuth Application:
    1. Call the GetOAuthAuthorizationURL stored procedure.
    2. Click Facebook Ads OAuth endpoint to open the endpoint in your browser.
  2. 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.
  3. Call the GetOAuthAuthorizationURL stored procedure with the CallbackURI input parameter set to the exact Redirect URI you specified in your application settings.
  4. Open the URL returned by the stored procedure in a browser.
  5. Log in and grant permissions to the driver. You are then redirected to the callback URL, which contains the verifier code.
  6. Save the value of the verifier code. Later you will set this in the OAuthVerifier connection property.

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

  • OAuthClientId: Set to the Client ID in your OAuth Integration settings.
  • OAuthClientSecret: Set to the Client Secret in your OAuth Integration settings.
  • OAuthVerifier: Set to the verifier code.
  • OAuthSettingsLocation: Set to persist the encrypted OAuth authentication values to the specified location.
  • InitiateOAuth: Set to REFRESH.

Connect to Data

After the OAuth settings file is generated, set the following properties to connect to data:

  • OAuthSettingsLocation: Set to the location containing the encrypted OAuth authentication values. Make sure this location gives read and write permissions to the provider to enable the automatic refreshing of the access token.
  • InitiateOAuth: Set to REFRESH.

Option 2: Transfer OAuth Settings

To install the driver on another machine, authenticate, and then transfer the resulting OAuth values:

  1. On a second machine, install the driver and connect with the following properties set:
    • OAuthSettingsLocation: Set to a writable location.
    • InitiateOAuth: Set to GETANDREFRESH.
    • OAuthClientId: Set to the client ID in your app settings.
    • OAuthClientSecret: Set to the client secret in your app settings.
    • CallbackURL: Set to the callback URL in your app settings.
  2. Test the connection to authenticate. The resulting authentication values are written and encrypted to the path specified by OAuthSettingsLocation. After 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 to REFRESH.
    • OAuthSettingsLocation: Set to the location of your OAuth settings file. Make sure this location gives read and write permissions to the driver to enable the automatic refreshing of the access token.

Requesting Additional Permissions

You may find while using the driver that Facebook returns an error stating your app does not have permissions to do a certain action. To resolve this, you must generate a new OAuth access token with the required permissions. Set the Scope property in the authentication step for a desktop application.

Web applications need to call the GetOAuthAuthorizationURL and GetOAuthAccessToken stored procedures, which have inputs for the permissions you would like to request.

Note that these are comma-separated lists of permissions, so you can request more than one per authorization request. You can find a list of available Facebook permissions here:

http://developers.facebook.com/docs/authentication/permissions/

Note that in some cases, permissions restrictions might not be due to missing but requestable Facebook Ads OAuth permissions, but instead might be due to missing OAuth app features, like Page Public Content Access or Page Public Metadata Access. These features are tied to the OAuth app as a whole, and cannot be approved or denied for individual OAuth access tokens requested by users. Consider Creating a Custom OAuth App if you need access to app features not available with the embedded OAuth app.

AuthenticateAsPage Property

Use the AuthenticateAsPage connection property if you want to post as a single page. To query collections of pages, leave AuthenticateAsPage blank, in which case CData tools automatically detect which page tokens to use.

The following sections compare the two options.

Posting as a Page

After authenticating to Facebook Ads with your user account, you can post, etc. as one of the pages you manage: Set the AuthenticateAsPage property to the Id of the page you want. You can find the Ids for all pages your account has access to by querying the Pages view.

Automatic Page

Facebook Ads has made a number of recent changes that require page tokens for most resources owned by a page. This can be troublesome if you manage multiple pages and want to execute the same queries across all pages (such as retrieving Insights). In order to make this work seamlessly with our tools, we have added a way to automatically detect the page token to use. For this to work, simply do not specify the AuthenticateAsPage. Note that the correct page token can only be resolved if the page id is specified as part of the target in the request. This means for some requests you will still need to manually specify AuthenticateAsPage.
