bucket STRING Required

Name of the bucket in which the object resides

object STRING Required

generation INTEGER

If present, selects a specific revision of this object (as opposed to the latest version, the default)

acl[].generation INTEGER

The content generation of the object, if applied to an object

acl[].id STRING

The ID of the access-control entry

acl[].object STRING

The name of the object, if applied to an object

acl[].projectTeam OBJECT

The project team associated with the entity, if any

acl[].projectTeam.projectNumber STRING

The project number

acl[].projectTeam.team STRING

The team

acl[].role STRING

The access permission for the entity

acl[].selfLink STRING

The link to this access-control entry

bucket STRING

The name of the bucket containing this object

cacheControl STRING

Cache-Control directive for the object data. If omitted, and the object is accessible to all anonymous users, the default will be public, max-age=3600

componentCount INTEGER

Number of underlying components that make up this object. Components are accumulated by compose operations

contentDisposition STRING

Content-Disposition of the object data

contentEncoding STRING

Content-Encoding of the object data

contentLanguage STRING

Content-Language of the object data

contentType STRING

Content-Type of the object data. If an object is stored without a Content-Type, it is served as application/octet-stream

crc32c STRING

CRC32c checksum, as described in RFC 4960, Appendix B; encoded using base64 in big-endian byte order. For more information about using the CRC32c checksum, see Hashes and ETags: Best Practices

customerEncryption OBJECT

Metadata of customer-supplied encryption key, if the object is encrypted by such a key

customerEncryption.encryptionAlgorithm STRING

The encryption algorithm

customerEncryption.keySha256 STRING

SHA256 hash value of the encryption key

etag STRING

HTTP 1.1 Entity tag for the object

eventBasedHold BOOLEAN

Whether an object is under event-based hold. Event-based hold is a way to retain objects until an event occurs, which is signified by the hold's release (i.e. this value is set to false). After being released (set to false), such objects will be subject to bucket-level retention (if any). One sample use case of this flag is for banks to hold loan documents for at least 3 years after loan is paid in full. Here, bucket-level retention is 3 years and the event is the loan being paid in full. In this example, these objects will be held intact for any number of years until the event has occurred (event-based hold on the object is released) and then 3 more years after that. That means retention duration of the objects begins from the moment event-based hold transitioned from true to false

generation INTEGER

The content generation of this object. Used for object versioning

id STRING

The ID of the object, including the bucket name, object name, and generation number

kind STRING

The kind of item this is. For objects, this is always storage#object

kmsKeyName STRING

Cloud KMS Key used to encrypt this object, if the object is encrypted by such a key

md5Hash STRING

MD5 hash of the data; encoded using base64. For more information about using the MD5 hash, see Hashes and ETags: Best Practices

mediaLink STRING

Media download link

metadata OBJECT

User-provided metadata, in key/value pairs

metadata.customKey.value STRING

User-provided metadata, in key/value pairs

metageneration INTEGER

The version of the metadata for this object at this generation. Used for preconditions and for detecting changes in metadata. A metageneration number is only meaningful in the context of a particular generation of a particular object

name STRING

The name of the object. Required if not specified by URL parameter

owner OBJECT

The owner of the object. This will always be the uploader of the object

owner.entity STRING

The entity, in the form user-userId

owner.entityId STRING

The ID for the entity

retentionExpirationTime DATE_TIME

A server-determined value that specifies the earliest time that the object's retention period expires. This value is in RFC 3339 format. Note 1: This field is not provided for objects with an active event-based hold, since retention expiration is unknown until the hold is removed. Note 2: This value can be provided even when temporary hold is set (so that the user can reason about policy without having to first unset the temporary hold)

selfLink STRING

The link to this object

size INTEGER

Content-Length of the data in bytes

storageClass STRING

Storage class of the object

temporaryHold BOOLEAN

Whether an object is under temporary hold. While this flag is set to true, the object is protected against deletion and overwrites. A common use case of this flag is regulatory investigations where objects need to be retained while the investigation is ongoing. Note that unlike event-based hold, temporary hold does not impact retention expiration time of an object

timeCreated DATE_TIME

The creation time of the object in RFC 3339 format

timeDeleted DATE_TIME

The deletion time of the object in RFC 3339 format. Will be returned if and only if this version of the object has been deleted

timeStorageClassUpdated DATE_TIME

The time at which the object's storage class was last changed. When the object is initially created, it will be set to timeCreated

updated DATE_TIME

The modification time of the object metadata in RFC 3339 format
