POST api/2.0/files/{folderId}/upload/create_session

Description

Creates a session to upload large files in multiple chunks to the folder with the ID specified in the request.

Parameters

Name	Description	Type	Example
folderId sent in url	Folder ID	string	some text
fileName sent in body	File name	string	some text
fileSize sent in body	File length in bytes	number	1234
relativePath sent in body	Relative path to the folder	string	some text

Remark

Each chunk can have different length but the length should be multiple of 512 and greater or equal to 10 mb. Last chunk can have any size. After the initial response to the request with the 200 OK status, you must get the location field value from the response. Send all your chunks to this location. Each chunk must be sent in the exact order the chunks appear in the file. After receiving each chunk, the server will respond with the current information about the upload session if no errors occurred. When the number of bytes uploaded is equal to the number of bytes you sent in the initial request, the server responds with the 201 Created status and sends you information about the uploaded file.
