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.

`predefinedDefaultObjectAcl`	`string`	Apply a predefined set of default object access controls to this bucket. Acceptable values are: "`authenticatedRead`": Object owner gets `OWNER` access, and `allAuthenticatedUsers` get `READER` access.

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. 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
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 overwritten.	writable
`retentionPolicy.retentionPeriod`	`string`	The period of time, in seconds, that objects in the bucket must be retained and cannot be deleted, overwritten, 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. Valid values include `MULTI_REGIONAL`, `REGIONAL`, `STANDARD`, `NEARLINE`, `COLDLINE`, and `DURABLE_REDUCED_AVAILABILITY`. If `storageClass` is not specified when the bucket is created, it defaults to `STANDARD`. For more information, 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
