Response Type:

Name	Type	Description
bold = required
value	info	The content.library.item.downloadsession.file.info instance containing the status of the file and its download link if available.
value.name	string	The name of the file.
value.size	long	The file size, in bytes. Optional. This field may not be available immediately. It is guaranteed to be set when the client finishes downloading the file.
value.bytes_transferred	long	The number of bytes that have been transferred by the server so far for making this file prepared for download. This value may stay at zero till the client starts downloading the file.
value.status	string	The preparation status (`UNPREPARED`, `PREPARE_REQUESTED`, `PREPARING`, `PREPARED`, `ERROR`) of the file. Defines the state of the file in preparation for download. Value is one of: UNPREPARED: The file hasn't been requested for preparation. PREPARE_REQUESTED: A prepare has been requested, however the server hasn't started the preparation yet. PREPARING: A prepare has been requested and the file is in the process of being prepared. PREPARED: Prepare succeeded. The file is ready for download. ERROR: Prepare failed.
value.download_endpoint	transfer_endpoint	Endpoint at which the file is available for download. The value is valid only when the content.library.item.downloadsession.file.info.status is PREPARED. Optional. This field won't be set until the file status is PREPARED.
value.download_endpoint.uri	URI	Transfer endpoint URI. The supported URI schemes are: `http`, `https`, `file`, and `ds`. An endpoint URI with the `ds` scheme specifies the location of the file on the datastore. The format of the datastore URI is: ds:///vmfs/volumes/uuid/path Some examples of valid file URI formats are: file:///path file:///C:/path file://unc-server/path When the transfer endpoint is a file or datastore location, the server can import the file directly from the storage backing without the overhead of streaming over HTTP.
value.download_endpoint.ssl_certificate_thumbprint	string	Thumbprint of the expected SSL certificate for this endpoint. Only used for HTTPS connections. The thumbprint is the SHA-1 hash of the DER encoding of the remote endpoint's SSL certificate. If set, the remote endpoint's SSL certificate is only accepted if it matches this thumbprint, and no other certificate validation is performed. Optional. If not specified, standard certificate validation is performed.
value.checksum_info	checksum_info	The checksum information of the file. When the download is complete, you can retrieve the checksum from the get operation to verify the checksum for the downloaded file. Optional. The checksum is always calculated for the downloaded file, but this field won't be set until the download is complete.
value.checksum_info.algorithm	string	The checksum algorithm (`SHA1`, `MD5`) used to calculate the checksum. Optional. If not specified the default checksum algorithm is SH_a1.
value.checksum_info.checksum	string	The checksum value calculated with content.library.item.file.checksum_info.algorithm.
value.error_message	localizable_message	Error message for a failed preparation when the prepare status is ERROR. Optional. This field won't be set unless there was an error with the file transfer.
value.error_message.id	string	Unique identifier of the localizable string or message template. This identifier is typically used to retrieve a locale-specific string or message template from a message catalog.
value.error_message.default_message	string	The value of this localizable string or message template in the `en_US` (English) locale. If vapi.std.localizable_message.id refers to a message template, the default message will contain the substituted arguments. This value can be used by clients that do not need to display strings and messages in the native language of the user. It could also be used as a fallback if a client is unable to access the appropriate message catalog.
value.error_message.args	string[]	Arguments to be substituted into a message template.

Errors:

HTTP Status Code	Type	Description
404	not_found	if the download session associated with `download_session_id` does not exist.
400	invalid_argument	if there is no file with the specified `file_name`.
