Use Requester Pays

Overview

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.

Set 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 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 given to users through roles. For example, users granted the Storage Admin role have all of the above storage.buckets permissions. Roles can be granted on the project that contains the bucket.

Set Requester Pays

To enable or disable Requester Pays on a bucket:

Console

1. In the Google Cloud console, go to the Cloud Storage Buckets page.
   

   Go to Buckets

2. In the list of buckets, find the bucket you want to set and locate the Requester pays column.

   The value in the column indicates the current state of Requester Pays for that bucket.

3. Click on the current state of Requester Pays for the desired bucket.

4. In the window that appears, click Turn on or Turn off, depending on the state you want to set for Requester Pays.

When enabled, a green bubble and On appear in the Requester pays column for the bucket. When disabled, a gray bubble and Off appear in the column.

To learn how to get detailed error information about failed Cloud Storage operations in the Google Cloud console, see Troubleshooting.

gsutil

Use the gsutil requesterpays set command:

gsutil requesterpays set STATE gs://BUCKET_NAME

Where:

• STATE is either on to enable Requester Pays or off to disable Requester Pays.

• BUCKET_NAME is the name of the relevant bucket. For example, my-bucket.

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. For instructions, see API authentication.

2. Create a JSON file that contains the following information:

   {
     "billing": {
       "requesterPays": STATE
     }
   }

   Where STATE is either true or false.

3. Use cURL to call the JSON API with a PATCH Bucket request:

   curl -X PATCH --data-binary @JSON_FILE_NAME \
     -H "Authorization: Bearer OAUTH2_TOKEN" \
     -H "Content-Type: application/json" \
     "https://storage.googleapis.com/storage/v1/b/BUCKET_NAME?fields=billing"

   Where:

   • JSON_FILE_NAME is the path for the JSON file that you created in Step 2.
   • OAUTH2_TOKEN is the name of the access token you generated in Step 1.
   • BUCKET_NAME is the name of the relevant bucket. For example, my-bucket.

XML API

1. Get an authorization access token from the OAuth 2.0 Playground. Configure the playground to use your own OAuth credentials. For instructions, see API authentication.

2. Create an XML file that contains the following information:

   <BillingConfiguration>
     <RequesterPays>STATE</RequesterPays>
   </BillingConfiguration>

   Where STATE is either Enabled or Disabled.

3. Use cURL to call the XML API with a PUT Bucket request and requesterpays query string parameter:

   curl -X PUT --data-binary @XML_FILE_NAME \
     -H "Authorization: Bearer OAUTH2_TOKEN" \
     "https://storage.googleapis.com/BUCKET_NAME?billing"

   Where:

   • XML_FILE_NAME is the path for the XML file that you created in Step 2.
   • OAUTH2_TOKEN is the name of the access token you generated in Step 1.
   • BUCKET_NAME is the name of the relevant bucket. For example, my-bucket.

Check whether Requester Pays is enabled

To check whether Requester Pays is enabled on a bucket:

Console

1. In the Google Cloud console, go to the Cloud Storage Buckets page.
   

   Go to Buckets

2. In the list of buckets, the Requester Pays status of each bucket is found in the Requester Pays column.

If enabled, the status is green and the word On appears.

gsutil

Use the gsutil requesterpays get command:

gsutil requesterpays get gs://BUCKET_NAME

Where BUCKET_NAME is the name of the relevant bucket. For example, my-bucket.

The response looks like the following if Requester Pays is enabled:

gs://my-bucket: Enabled

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. For instructions, see API authentication.

2. Use cURL to call the JSON API with a GET Bucket request:

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

   Where:

   • OAUTH2_TOKEN is the name of the access token you generated in Step 1.
   • BUCKET_NAME is the name of the relevant bucket. For example, my-bucket.

XML API

1. Get an authorization access token from the OAuth 2.0 Playground. Configure the playground to use your own OAuth credentials. For instructions, see API authentication.

2. Use cURL to call the XML API with a GET Bucket request and billing query string parameter:

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

   Where:

   • OAUTH2_TOKEN is the name of the access token you generated in Step 1.
   • BUCKET_NAME is the name of the relevant bucket. For example, my-bucket.

Access 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. In the Google Cloud console, go to the Cloud Storage Buckets page.
   

   Go to Buckets

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:

gsutil -u PROJECT_IDENTIFIER cp gs://BUCKET_NAME/OBJECT_NAME OBJECT_DESTINATION

Where:

• PROJECT_IDENTIFIER is the ID or number of the project to be billed. For example, my-project.
• BUCKET_NAME is the name of the relevant bucket. For example, my-bucket.
• OBJECT_NAME is the name of the object you want to download. For example, pets/dog.png.
• OBJECT_DESTINATION is the location where you want to save your object. For example, Desktop/dog.png.
