Objects: insert

Stores a new object and metadata. For tips on uploading to Cloud Storage, see best practices. For examples of performing object uploads with different Cloud Storage tools and client libraries, see the Uploading Objects guide.

This method accepts uploaded object data with the following characteristics:

Maximum file size: 5 TB
Accepted Media MIME types: */*

This method generally requires the following headers be included in a request:

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

Note: Metadata-only requests are not allowed. To change an object's metadata, use either the update or patch methods.

To provide a customer-supplied encryption key along with the object upload, use the headers listed on the Encryption page in your request.

Request

HTTP request

Note: The request endpoint for this method differs from typical Cloud Storage JSON API endpoints.

POST https://storage.googleapis.com/upload/storage/v1/b/bucket/o

Parameters

Parameter name	Value	Description
Path parameters
`bucket`	`string`	Name of the bucket in which to store the new object. Overrides the provided object metadata's `bucket` value, if any.
Required query parameters
`uploadType`	`string`	The type of upload request to the /upload URI. Acceptable values are: `media` - Simple upload. Upload the object data only, without any metadata. `multipart` - Multipart upload. Upload both the object data and its metadata, in a single request. `resumable` - Resumable upload. Upload the object data in a resumable fashion, using a series of at least two requests where the first request includes the metadata.
Optional query parameters
`contentEncoding`	`string`	If set, sets the `contentEncoding` property of the final object to this value. Setting this parameter is equivalent to setting the `contentEncoding` metadata property. This can be useful when uploading an object with `uploadType=media` to indicate the encoding of the content being uploaded.
`ifGenerationMatch`	`long`	Makes the operation conditional on whether the object's current generation matches the given value. Setting to 0 makes the operation succeed only if there are no live versions of the object.
`ifGenerationNotMatch`	`long`	Makes the operation conditional on whether the object's current generation does not match the given value. If no live object exists, the precondition fails. Setting to 0 makes the operation succeed only if there is a live version of the object.
`ifMetagenerationMatch`	`long`	Makes the operation conditional on whether the object's current metageneration matches the given value.
`ifMetagenerationNotMatch`	`long`	Makes the operation conditional on whether the object's current metageneration does not match the given value.
`kmsKeyName`	`string`	Resource name of the Cloud KMS key that will be used to encrypt the object. Overrides the object metadata's `kms_key_name` value, if any.
`name`	`string`	Name of the object. Required when the object metadata is not otherwise provided. Overrides the object metadata's `name` value, if any. For information about how to URL encode object names to be path safe, see Encoding URI path parts.
`predefinedAcl`	`string`	Apply a predefined set of access controls to this object. 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 `noAcl`, unless the object resource specifies the `acl` property, when it defaults to `full`. Acceptable values are: "`full`": Include all properties. "`noAcl`": Omit the `owner`, `acl` property.
`userProject`	`string`	The project to be billed for this request. Required for Requester Pays buckets.

Request body

In the request body, supply the object data. When performing a multipart upload, which allows you to include object metadata as part of the request, supply the following properties.

Property name	Value	Description	Notes
Optional Properties
`acl[]`	`list`	Access controls on the object, containing one or more objectAccessControls Resources. Do not supply this field if `iamConfiguration.uniformBucketLevelAccess.enabled` is `true` for the bucket to which you are uploading the object.	writable
`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`.	writable
`contentDisposition`	`string`	Content-Disposition of the object data.	writable
`contentEncoding`	`string`	Content-Encoding of the object data.	writable
`contentLanguage`	`string`	Content-Language of the object data.	writable
`contentType`	`string`	Content-Type of the object data. If an object is stored without a Content-Type, it is served as application/octet-stream.	writable
`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.	writable
`eventBasedHold`	`boolean`	Whether or not the object is subject to an event-based hold.	writable
`md5Hash`	`string`	MD5 hash of the data; encoded using base64. For more information about using the MD5 hash, see Hashes and ETags: Best Practices.	writable
`metadata`	`object`	User-provided metadata, in key/value pairs.	writable
`metadata.(key)`	`string`	An individual metadata entry.	writable
`name`	`string`	The name of the object. Required if not specified by URL parameter.	writable
`storageClass`	`string`	Storage class of the object.	writable
`temporaryHold`	`boolean`	Whether or not the object is subject to a temporary hold.	writable

Response

If successful, this method returns an object resource in the response body.
