Create OAuth authorization credentials for a Looker (Google Cloud core) instance

An OAuth client must be set up and OAuth credentials must be generated as part of Looker (Google Cloud core) instance creation, even if you want to use a different authentication method for authenticating your users into a Looker (Google Cloud core) instance.

Required roles

To use the Google Cloud console to create and edit OAuth credentials, you need the following permissions. (To hide the list of permissions, collapse the Required permissionssection.)

You might also be able to get the required permissions through custom roles or other predefined roles . For more information about granting roles, see the Manage access to projects, folders, and organizations page in the Identity and Access Management (IAM) documentation.

Before you create a Looker (Google Cloud core) instance

Before you create a Looker (Google Cloud core) instance, complete the steps that are described in these sections:

Generate the OAuth client ID and client secret
Configure the user consent screen, scopes, and test users

Generate the OAuth client ID and client secret

First, create an OAuth client and generate the client ID and client secret for that client. These values are required during creation of the Looker (Google Cloud core) instance.

You can set up the OAuth client in any Google Cloud project you want. It doesn't need to be the same project as the Looker (Google Cloud core) instance. However, the Looker (Google Cloud core) API must be enabledin this project.

To create the client and its credentials, follow these steps:

Navigate to the project that you want to create the OAuth client in.
Navigate to APIs & Services > Credentials.
From the Credentialspage, click Create Credentials.
From the drop-down menu, select OAuth client ID.
In the Application typedrop-down, select Web application.
In the Namefield, enter a name for your OAuth client.
At this point, you don'tneed to add URIs in the Authorized JavaScript originsor Authorized redirect URIssections.
Click Create.

After you click Create, an OAuth client createdwindow appears. This window displays the client ID and client secret created for your OAuth client. These values will be required when you create the Looker (Google Cloud core) instance .

Optionally, click Download JSONto download the credential information in a JSON file. To close the window, click OK.

Configure the user consent screen, scopes, and test users

Next, you may want to configure the consent screen. The consent screen is shown to a user of the Looker (Google Cloud core) instance at their first login and at any point when their authorization expires or is revoked by the user .

Follow the instructions on the Configure the OAuth consent screen and choose scopes documentation page. While configuring your screen, complete the following settings as described:

In the Brandingsection, under Authorized domains, the domain must match the domain of the Looker (Google Cloud core) instance that uses the OAuth credentials. If you are going to create a custom domain for your Looker (Google Cloud core) instance and know the domain that you will assign to it, you can enter it now. Otherwise, you can leave this field empty; it will be automatically populated when you add the authorized redirect URI after the Looker (Google Cloud core) instance is created.
In the Audiencesection, under User Type, select one of the following:
- Internal: This setting is the default. Only users within your organization can access the instance once they are added through IAM .
- Make external: Users with any kind of Google Account can access the instance once they are added through IAM .
Note: If you want a user such as Google Support to access your instance using OAuth and IAM, User Typemust be set to External, and the Support user must be added through IAM . You can edit the User Typesetting at any point.

During Looker (Google Cloud core) instance creation

When you are creating the Looker (Google Cloud core) instance , add the OAuth client ID and client secret in the OAuth Application Credentialssection . You cannot create an instance without OAuth credentials. Find the OAuth client ID and client secret by navigating to the OAuth client in the Google Cloud console.

After you create a Looker (Google Cloud core) instance

Complete the following instructions to finish configuration. When you add an authorized redirect URI, it will be added to your OAuth consent screen as an authorized domain.

Add the authorized redirect URI to the OAuth client

If you haven't done so already, follow these steps to enter the URL of the newly created Looker (Google Cloud core) instance into the OAuth client.

After you have created a Looker (Google Cloud core) instance, find and copy the URL for the instance. You can find the URL on the Instancespage .

Note: If you are setting up a custom domain for your instance, be sure to complete that setup before copying the URL. Once you add the custom domain to the OAuth client, users will no longer be able to log in to the autogenerated instance URL that was granted when the instance was created, even if that domain is also in the OAuth client.
In the Google Cloud console, navigate to APIs & Services > Credentials.
Under the OAuth 2.0 Client IDsheading, click the name of the client you created .
In the Authorized redirect URIssection, click Add URI.
Paste the URL of the Looker (Google Cloud core) instance into the URIsfield. Add /oauth2callback to the end of the URL. For example: https://uuid.looker.app/oauth2callback .

If you are going to set up OAuth authorization for BigQuery , you can also add a second redirect URI that points to the URL of the Looker (Google Cloud core) instance followed by /external_oauth/redirect added to the end of the URL. For example: https://uuid.looker.app/external_oauth/redirect .
Click Save.

It may take from five minutes to a few hours for the update to take effect.

Manage users

Once the OAuth client is configured and the Looker (Google Cloud core) instance is created , you can choose the authentication method for your instance.

If using OAuth as your primary authentication method, complete the steps as described on the Use Google OAuth for Looker (Google Cloud core) user authentication documentation page to complete OAuth setup for user authentication.

Once your authentication method is set up, you can add or remove users through your identity provider and manage them within Looker .

Edit the OAuth client for a Looker (Google Cloud core) instance

If you want, you can edit or change the OAuth credentials for your Looker (Google Cloud core) instance by following these steps:

Set up the new client or credentials.
In the Google Cloud console, from the Instancespage, click on an instance's name to open the DETAILSpage.
From the DETAILSpage, click Edit.
On the Edit Looker (Google Cloud core) instancepage, enter the new values in the OAuth Client IDand OAuth Client Secretfields.
Click Save.
