Buckets: update

Updates a bucket. Changes to the bucket are readable immediately after writing, but configuration changes may take time to propagate. Try it now.

Note: This method sets the complete metadata of a bucket. You should generally use the PATCH method instead, which changes only metadata you define in the request, while leaving other metadata unaffected.

The authenticated user must have sufficient permission to use this method.

Request

HTTP request

PUT https://storage.googleapis.com/storage/v1/b/bucket

In addition to standard query parameters, the following query parameters apply to this method.

To see an example of how to include query parameters in a request, see the JSON API Overview page.

Parameters

Parameter name	Value	Description
Path parameters
bucket	string	Name of a bucket.
Optional query parameters
ifMetagenerationMatch	long	Makes the return of the bucket metadata conditional on whether the bucket's current metageneration matches the given value.
ifMetagenerationNotMatch	long	Makes the return of the bucket metadata conditional on whether the bucket's current metageneration does not match the given value.
predefinedAcl	string	Apply a predefined set of access controls to this bucket. Acceptable values are: authenticatedRead: Project team owners get OWNER access, and allAuthenticatedUsers get READER access. private: Project team owners get OWNER access. projectPrivate: Project team members get access according to their roles. publicRead: Project team owners get OWNER access, and allUsers get READER access. publicReadWrite: Project team owners get OWNER access, and allUsers get WRITER access. If iamConfiguration.uniformBucketLevelAccess.enabled is set to true, requests that include this parameter fail with a 400 Bad Request response.

Acceptable values are: authenticatedRead: Object owner gets OWNER access, and allAuthenticatedUsers get READER access. bucketOwnerFullControl: Object owner gets OWNER access, and project team owners get OWNER access. bucketOwnerRead: Object owner gets OWNER access, and project team owners get READER access. private: Object owner gets OWNER access. projectPrivate: Object owner gets OWNER access, and project team members get access according to their roles. publicRead: Object owner gets OWNER access, and allUsers get READER access. If iamConfiguration.uniformBucketLevelAccess.enabled is set to true, requests that include this parameter fail with a 400 Bad Request response.
projection	string	Set of properties to return. Defaults to full. Acceptable values are: full: Include all properties. noAcl: Omit owner, acl and defaultObjectAcl properties.

Request body

In the request body, supply a bucket resource with the following properties:

Property name	Value	Description	Notes
Required Properties
acl[]	list	Access controls on the bucket, containing one or more bucketAccessControls Resources. Note: ACLs do not apply in buckets where iamConfiguration.uniformBucketLevelAccess.enabled is set to true. Requests to such buckets fail with a 400 Bad Request response if the request contains an acl[] property.	writable
Optional Properties
billing	object	The bucket's billing configuration.	writable
billing.requesterPays	boolean	When set to true, Requester Pays is enabled for this bucket.	writable
cors[]	list	The bucket's Cross-Origin Resource Sharing (CORS) configuration.	writable
cors[].maxAgeSeconds	integer	The value, in seconds, to return in the Access-Control-Max-Age header used in preflight responses.	writable
cors[].method[]	list	The list of HTTP methods on which to include CORS response headers, ("GET", "OPTIONS", "POST", etc) Note: "*" is permitted in the list of methods, and means "any method".	writable
cors[].origin[]	list	The list of Origins eligible to receive CORS response headers. Note: "*" is permitted in the list of origins, and means "any Origin".	writable
cors[].responseHeader[]	list	The list of HTTP headers other than the simple response headers to give permission for the user-agent to share across domains.	writable
defaultEventBasedHold	boolean	Whether or not to automatically apply an eventBasedHold to new objects added to the bucket.	writable
defaultObjectAcl[]	list	Default access controls to apply to new objects when no ACL is provided. This list defines an entity and role for one or more defaultObjectAccessControls Resources. If iamConfiguration.uniformBucketLevelAccess.enabled is set to true, this field is omitted in responses, and requests that specify this field fail with a 400 Bad Request response.	writable
encryption	object	Encryption configuration for a bucket.	writable
encryption.defaultKmsKeyName	string	A Cloud KMS key that will be used to encrypt objects inserted into this bucket, if no encryption method is specified.
iamConfiguration	object	The bucket's IAM configuration.	writable
iamConfiguration.uniformBucketLevelAccess	object	The bucket's uniform bucket-level access configuration. Note: iamConfiguration also includes the bucketPolicyOnly field, which uses a legacy name but has the same functionality as the uniformBucketLevelAccess field. We recommend only using uniformBucketLevelAccess, as specifying both fields may result in unreliable behavior.	writable
iamConfiguration.uniformBucketLevelAccess.enabled	boolean	Whether or not the bucket uses uniform bucket-level access. If set, access checks only use bucket-level IAM policies or above.	writable
labels	object	User-provided bucket labels, in key/value pairs.	writable
labels.(key)	string	An individual label entry.	writable
lifecycle	object	The bucket's lifecycle configuration. See lifecycle management for more information.	writable
logging	object	The bucket's logging configuration, which defines the destination bucket and optional name prefix for the current bucket's logs.	writable
logging.logBucket	string	The destination bucket where the current bucket's logs should be placed.	writable
logging.logObjectPrefix	string	A prefix for log object names. The default prefix is the bucket name.	writable
retentionPolicy	object	The bucket's retention policy, which defines the minimum age an object in the bucket must reach before it can be deleted or replaced.	writable
retentionPolicy.retentionPeriod	string	The period of time, in seconds, that objects in the bucket must be retained and cannot be deleted, replaced, or made noncurrent. The value must be less than 3,155,760,000 seconds.	writable
storageClass	string	The bucket's default storage class, used whenever no storageClass is specified for a newly-created object. For available storage classes, see Storage classes.	writable
versioning	object	The bucket's versioning configuration.	writable
versioning.enabled	boolean	While set to true, versioning is fully enabled for this bucket.	writable
website	object	The bucket's website configuration, controlling how the service behaves when accessing bucket contents as a web site. See the Static Website Examples for more information.	writable
website.mainPageSuffix	string	If the requested object path is missing, the service will ensure the path has a trailing '/', append this suffix, and attempt to retrieve the resulting object. This allows the creation of index.html objects to represent directory pages.	writable
website.notFoundPage	string	If the requested object path is missing, and any mainPageSuffix object is missing, if applicable, the service will return the named object from this bucket as the content for a 404 Not Found result.	writable
