# Set up the Google Cloud Pub Sub Spoke

Integrate the ServiceNow instance and Google Cloud Pub Sub by creating a custom OAuth application in Google Cloud account to authenticate ServiceNow requests.

## Before you begin

-   Request an Integration Hub subscription.
-   Activate the Google Cloud Pub Sub spoke.
-   Role required: admin.

## Create a custom application

Create a custom OAuth application in your Google Cloud Platform account to enable OAuth 2.0 authentication with the Google Cloud Pub Sub spoke.

### Before you begin

Role required: admin

### Procedure

1.  Register a new custom application by navigating to [https://console.cloud.google.com/](https://console.cloud.google.com/).

2.  Create a project with your administrator credentials, and open the project.

3.  From the APIs & Services menu, select **OAuth consent screen**, enter the application name, and specify the Authorized domain `service-now.com`.

    The OAuth client window shows your client ID and client secret.

8.  Copy these two values to a text file so that you can use them when you [Register Google Cloud Pub Sub as an OAuth provider](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/integrate-applications/integration-hub/setup-google-pubsub.md).

    The client ID and secret can always be accessed in the Google APIs &amp; Services interface. Click **Credentials** and select the OAuth 2.0 client ID name.


## Register Google Cloud Pub Sub as an OAuth provider

Use the information generated during the Google Cloud Pub Sub application configuration to register Google Cloud as an OAuth provider and allow the ServiceNow instance to request OAuth 2.0 tokens.

### Before you begin

Role required: admin.

Configure the Google Identity and Access Spoke.

### Procedure

1.  Navigate to **System OAuth** &gt; **Application Registry**.

2.  Open for the record, **Google Cloud Pub Sub**.

3.  On the form, fill these values.
