Fields
`objectConditions`	`object (ObjectConditions)` Only objects that satisfy these object conditions are included in the set of data source and data sink objects. Object conditions based on objects' "last modification time" do not exclude objects in a data sink.
`transferOptions`	`object (TransferOptions)` If the option `deleteObjectsUniqueInSink` is `true` and time-based object conditions such as 'last modification time' are specified, the request fails with an `INVALID_ARGUMENT` error.
`transferManifest`	`object (TransferManifest)` A manifest file provides a list of objects to be transferred from the data source. This field points to the location of the manifest file. Otherwise, the entire source bucket is used. ObjectConditions still apply.
`sourceAgentPoolName`	`string` Specifies the agent pool name associated with the posix data source. When unspecified, the default name is used.

  "cloudfrontDomain": string,
  "credentialsSecret": string,

  // Union field private_network can be only one of the following:

  // End of list of possible types for union field private_network.
}

Fields
`bucketName`	`string` Required. S3 Bucket name (see Creating a bucket).
`awsAccessKey`	`object (AwsAccessKey)` Input only. AWS access key used to sign the API requests to the AWS S3 bucket. Permissions on the bucket must be granted to the access ID of the AWS access key. For information on our data retention policy for user credentials, see User credentials.
`path`	`string` Root path to transfer objects. Must be an empty string or full path name that ends with a '/'. This field is treated as an object prefix. As such, it should generally not begin with a '/'.
`roleArn`	`string` The Amazon Resource Name (ARN) of the role to support temporary credentials via `AssumeRoleWithWebIdentity`. For more information about ARNs, see IAM ARNs. When a role ARN is provided, Transfer Service fetches temporary credentials for the session using a `AssumeRoleWithWebIdentity` call for the provided role using the `GoogleServiceAccount` for this project.
`cloudfrontDomain`	`string` Optional. The CloudFront distribution domain name pointing to this bucket, to use when fetching. See Transfer from S3 via CloudFront for more information. Format: `https://{id}.cloudfront.net` or any valid custom domain. Must begin with `https://`.
`credentialsSecret`	`string` Optional. The Resource name of a secret in Secret Manager. AWS credentials must be stored in Secret Manager in JSON format: { "accessKeyId": "ACCESS_KEY_ID", "secretAccessKey": "SECRET_ACCESS_KEY" } `GoogleServiceAccount` must be granted `roles/secretmanager.secretAccessor` for the resource. See Configure access to a source: Amazon S3 for more information. If `credentialsSecret` is specified, do not specify `roleArn` or `awsAccessKey`. Format: `projects/{projectNumber}/secrets/{secret_name}`
Union field `private_network`. `private_network` can be only one of the following:
`managedPrivateNetwork`	`boolean` Egress bytes over a Google-managed private network. This network is shared between other users of Storage Transfer Service.

For information on our data retention policy for user credentials, see User credentials.

JSON representation
{ "accessKeyId": string, "secretAccessKey": string }

Fields

Fields
`accessKeyId`	`string` Required. AWS access key ID.
`secretAccessKey`	`string` Required. AWS secret access key. This field is not returned in RPC responses.

accessKeyId

string

Required. AWS access key ID.

secretAccessKey

string

Required. AWS secret access key. This field is not returned in RPC responses.

HttpData

An HttpData resource specifies a list of objects on the web to be transferred over HTTP. The information of the objects to be transferred is contained in a file referenced by a URL. The first line in the file must be "TsvHttpData-1.0", which specifies the format of the file. Subsequent lines specify the information of the list of objects, one object per list entry. Each entry has the following tab-delimited fields:

HTTP URL — The location of the object.
Length — The size of the object in bytes.
MD5 — The base64-encoded MD5 hash of the object.

For an example of a valid TSV file, see Transferring data from URLs.

When transferring data based on a URL list, keep the following in mind:

When an object located at http(s)://hostname:port/<URL-path> is transferred to a data sink, the name of the object at the data sink is <hostname>/<URL-path>.
If the specified size of an object does not match the actual size of the object fetched, the object is not transferred.
If the specified MD5 does not match the MD5 computed from the transferred bytes, the object transfer fails.
Ensure that each URL you specify is publicly accessible. For example, in Cloud Storage you can share an object publicly and get a link to it.
Storage Transfer Service obeys robots.txt rules and requires the source HTTP server to support Range requests and to return a Content-Length header in each response.
ObjectConditions have no effect when filtering objects to transfer.

JSON representation
{ "listUrl": string }

Fields

Fields
`listUrl`	`string` Required. The URL that points to the file that stores the object list entries. This file must allow public access. Currently, only URLs with HTTP and HTTPS schemes are supported.

string

AzureBlobStorageData

An AzureBlobStorageData resource can be a data source, but not a data sink. An AzureBlobStorageData resource represents one Azure container. The storage account determines the Azure endpoint. In an AzureBlobStorageData resource, a blobs's name is the Azure Blob Storage blob's key name.

JSON representation
{ "storageAccount": string, "azureCredentials": { object (`AzureCredentials`) }, "container": string, "path": string, "credentialsSecret": string }

Fields
`storageAccount`	`string` Required. The name of the Azure Storage account.
`azureCredentials`	`object (AzureCredentials)` Required. Input only. Credentials used to authenticate API requests to Azure. For information on our data retention policy for user credentials, see User credentials.
`container`	`string` Required. The container to transfer from the Azure Storage account.
`path`	`string` Root path to transfer objects. Must be an empty string or full path name that ends with a '/'. This field is treated as an object prefix. As such, it should generally not begin with a '/'.
`credentialsSecret`	`string` Optional. The Resource name of a secret in Secret Manager. The Azure SAS token must be stored in Secret Manager in JSON format: { "sasToken" : "SAS_TOKEN" } `GoogleServiceAccount` must be granted `roles/secretmanager.secretAccessor` for the resource. See Configure access to a source: Microsoft Azure Blob Storage for more information. If `credentialsSecret` is specified, do not specify `azureCredentials`. Format: `projects/{projectNumber}/secrets/{secret_name}`

`protocol`	`enum (NetworkProtocol)` Specifies the network protocol of the agent. When not specified, the default value of NetworkProtocol NETWORK_PROTOCOL_HTTPS is used.
`listApi`	`enum (ListApi)` The Listing API to use for discovering objects. When not specified, Transfer Service will attempt to determine the right API to use.
