Supported Frameworks

Announcements and updates

For API and client library updates and news, please follow our Google Ads Developers blog:

Getting started

  1. Install your library. We recommend using the following Nuget distribution:
  • Google.Dfp: Ad Manager API DotNet Client Library

You can learn more about the nuget package manager at For other distribution options, see the alternative distribution options below.

  1. Setup your OAuth2 credentials.

The and Ad Manager API uses OAuth2 as the authentication mechanism. Follow the appropriate guide below based on your use case.

If you're accessing an API using your own credentials...

If you're accessing an API on behalf of clients...

Alternative distribution options

Binary distribution

The binary distribution of the Ads API .NET library consists of a precompiled version of the library as a .NET assembly, code examples for using the library, and library documentation. If you are interested in just using the library and not in its internals, and you don't use nuget package manager in your development environment, then you should download this distribution.

The contents of this distribution are as follows:

      - Precompiled assemblies.
      - Documentation xmls for the assemblies.
       Code examples, in C# and VB.NET (when available).
    Visual Studio solution file

To run the code examples:

  • Open Visual Studio solution file in the root folder of the binary distribution in Microsoft Visual Studio
  • Open App.config for the examples project and follow the instructions in the file to enter required configuration values.
  • Save and close App.config.
  • Open the Properties dialog for the Examples project (Right click the Examples project of your choice in the Solution Explorer and select the Properties option from the context menu.).
  • Navigate to the Debug Tab and enter the command line options. The command line options are of the form version.examplename. For instance, v202308.GetCurrentNetwork is the command line option to run GetCurrentNetwork example in v202308 version of the Ad Manager API.
  • Compile and run the Examples project.

Alternatively, each code example has a main() method, so you can set the appropriate code example as the Startup object (Select the Application tab on the Examples Properties dialog and pick the desired class from the "Startup object" dropdown.).

To use the library in a new project:

  • Create a new Visual Studio project of your choice (for instance, a C# Windows application).
  • Copy the lib folder from the binary distribution to your project folder. Add references to all the assemblies in this folder in your project.
  • Add a reference to System.Web.Services in your project.
  • Copy examples\App.config to your project directory and add it to your project.
  • Edit the required keys in App.config. If your application has its own App.config, then you need to merge its contents with the contents of examples\App.config.
  • Make a call to the library, e.g.:
// Create an appropriate AdsUser instance.
AdManagerUser user = new AdManagerUser();

// Create the required service.
using (NetworkService networkService = user.GetService<NetworkService>())
    // make calls to service class.
