Generate credentials

Requests to the Bid Manager API must use OAuth 2.0 for authentication. This page explains how to generate the OAuth 2.0 credentials and use them to authenticate your users.

Choose a project

OAuth 2.0 credentials are generated by a Google Cloud project. You need to create or select a project in the Google Cloud console and enable the API.

You can create a new project, or use an existing one.

Create a new project

To create a project and activate the Bid Manager API, follow the steps in the Google Cloud console.

Use an existing project

To activate the Bid Manager API for an existing project, complete the following steps:

1. Open the API Library in the Google Cloud console. If prompted, select a project or create a new one. The API Library lists all available APIs, grouped by product family and popularity. The Bid Manager API is labeled DoubleClick Bid Manager API.
2. If you don't see the API you want to activate in the list, use the search bar to find it.
3. Select the API you want to activate, then click Enable.
4. If prompted, activate billing.
5. If prompted, accept the Terms of Service for the API.

Generate credentials

This section explains how to generate an OAuth 2.0 client ID to authenticate your Bid Manager API requests, after you've chosen a project.

To create an OAuth 2.0 client ID to use with the installed application flow, complete the following steps:

1. Configure a Google Cloud console project.
2. Open the Credentials page in the Google Cloud console.
3. Click Create Credentials > OAuth client ID.
4. Select an appropriate application type when prompted. The Java and Python code snippets in the Bid Manager API developer guides are for a Desktop app. The PHP code snippets are for a Web application.
5. Enter any additional required information. If this is your first time creating a client ID, you can configure your consent screen by clicking Configure consent screen. You won't get a prompt to configure your consent screen again after you do it the first time, but you can update this information at any time.
6. Click Create.

When you're done, you get an OAuth 2.0 client ID and client secret, which you can download in JSON format and save for later use.

Warning: OAuth credentials are sensitive information. You should download them directly from the Google Cloud console, and shouldn't share them.

Configure the user consent screen

When you use OAuth 2.0 for authentication, your users are authenticated after they agree to terms on a user consent screen.

To set up your project's consent screen, complete the following steps:

1. Open the OAuth consent screen page in the Google Cloud console. If prompted, select a project or create a new one.
2. Fill out the form, then click Save.
