• [long] filesize: The size of the video file in bytes. This parameter must be an unsigned integer value no
greater than 5000000000 (i.e. 5GB). A descriptive error will be returned if the value is negative.
• [int] chunksCount: The number of chunks the file consists of (starting at 1). The optimal chunk size is 256KiB.
Files that are larger than this chunk size must be split into smaller parts by the client. Multiple chunks should be
uploaded using multiple
AppendChunk() calls specifying the same upload token.
• [string] sha1Hash: The SHA1 hash of the current file. The server performs verification of the uploaded file
using the specified hash. A descriptive error will be returned if the specified hash does not match the hash value
calculated by the server. This parameter is optional; the server-side hash verification process is skipped if this
parameter is not specified.
• [enum: Auto, Image, Video, Audio, Webpage] contentType: The type of the content file. The default
type is Image.
• [DateTime] fileLastModifiedDate: A value representing the last time the associated file was modified on
the user storage (e.g. the "Date modified" value in Windows). This value can also be initialized later by modifying
the
Content entity.
• [string] virtualPath: The path in the BSN Library to which the file should be uploaded (the default is
“\Shared\Incoming\”). If the path does not exist, it will be created. It must also contain leading and trailing slashes
and be no longer than 128 characters.
• [base64Binary] fileThumb: The optional thumbnail data as a binary attachment. This parameter will be
generated by the server if it is not specified.
