Using Requester Pays

This page describes how to set up the Requester Pays feature and gives an example of making a request on a bucket that has enabled the Requester Pays feature. For a description of this feature, see Requester Pays.

Setting up Requester Pays

The following sections show how to turn Requester Pays on and off, as well as how to check to see if Requester Pays is enabled on a bucket.

Prerequisites

1. You should have the storage.buckets.get permission, which allows you to get the requester pays status for a bucket and is also required for enabling and disabling Requester Pays with the Google Cloud Platform Console or gsutil.

2. When enabling or disabling Requester Pays, you must have the storage.buckets.update permission.

3. When disabling Requester Pays, you must either include a billing project in your request or else have the resourcemanager.projects.createBillingAssignment permission. See Requester Pays Use and access requirements for more information.

Permissions are granted to users through roles. For example, users with roles/storage.admin have all of the above storage.buckets permissions. Roles can be added to the project that contains the bucket.

Enabling Requester Pays

To enable Requester Pays on a bucket:

Console

1. Open the Cloud Storage browser in the Google Cloud Platform Console.
   Open the Cloud Storage browser

2. In the list of buckets, find the bucket you want to enable, and click the Off button in the Requester pays column.

3. In the window that appears, click Enable.

Once enabled, a green bubble and On appear in the Requester pays column for the bucket.

gsutil

Use the gsutil requesterpays set on command, replacing [VALUES_IN_BRACKETS] with the appropriate values:

gsutil requesterpays set on gs://[BUCKET_NAME]

REST APIs

JSON API

1. Get an authorization access token from the OAuth 2.0 Playground. Configure the playground to use your own OAuth credentials.
2. Use cURL to call the JSON API with a GET Bucket request, replacing [VALUES_IN_BRACKETS] with the appropriate values:

   curl -X GET -H "Authorization: Bearer [OAUTH2_TOKEN]" \
       "https://www.googleapis.com/storage/v1/b/[BUCKET_NAME]?fields=billing"

XML API

1. Get an authorization access token from the OAuth 2.0 Playground. Configure the playground to use your own OAuth credentials.
2. Use cURL to call the XML API with a GET Bucket request and billing query string parameter, replacing [VALUES_IN_BRACKETS] with the appropriate values:

   curl -X GET \
       -H "Authorization: Bearer [OAUTH2_TOKEN]" \
       "https://storage.googleapis.com/[BUCKET_NAME]?billing"

Accessing Requester Pays buckets

The following example shows how to include a billing project so that you can download an object stored in a Requester Pays bucket. Use a similar procedure to perform other requests on the Requester Pays bucket or on objects within it. See Requester Pays access requirements for prerequisite considerations.

Important: Buckets that have Requester Pays disabled still accept requests that include a billing project, and charges are applied to the billing project supplied in the request. Consider any billing implications prior to including a billing project in all of your requests.

Console

Note: If you previously used the Console to access a given Requester Pays bucket, you have immediate access to the bucket and can download the object as you normally would. The project you previously specified as the billing project is used for this subsequent access. You can change the project you bill by clicking the Change project button located above the list of objects in the bucket.

1. Open the Cloud Storage browser in the Google Cloud Platform Console.
   Open the Cloud Storage browser

2. In the list of buckets, click on the name of the bucket that contains the object you want to download.

3. In the window that appears, use the dropdown menu to select a project for billing.

4. Check the checkbox to confirm you are authorized to use the selected project for billing purposes.

5. Click Save.

6. Download the object as you normally would.

gsutil

Use the -u flag in your request along with the ID of the project to be billed, replacing [VALUES_IN_BRACKETS] with the appropriate values:

gsutil -u [PROJECT_ID] cp gs://[BUCKET_NAME]/[OBJECT_NAME] [OBJECT_DESTINATION]
