Get Content

Description: Returns either a list of folders or a list of files.

Required Parameters:

• folder_key : The key that identifies the folder to be returned. If not passed, then it will return the root folder (session token is then required).

• session_token : A type 1 or type 2 session token. (Type 2 will require a call signature).

• signature : This is the call signature that is required to authenticate a type 2 session token transaction.
• content_type : Request what type of content ('folders' or 'files'). If not passed, it defaults to 'folders'.
• filter : Filter by privacy and/or by filetype. This is a comma-separated list of file types and privacy options and can take one or more of the following values : "public", "private", "image", "video", "audio", "document", "spreadsheet", "presentation", "application", "archive", "data", and "development". If content_type is 'folders', only 'public' and 'private' filters are honored.
• device_id : Specify which device to return the myfiles data from. If not set, it defaults to the cloud.
• order_by : 'name', 'created', 'size', 'downloads' (default 'name'). In case of requesting folders, only 'name' and 'created' are considered; anything else will default to 'name'.
• order_direction : Order direction: 'asc' or 'desc' (default 'asc').
• chunk : The chunk number starting from 1.
• details : "yes", "no", or "shallow" ("no" by default). If "yes", the API returns the '''total_files''', '''total_folders''', and '''total_size''' for all the contained folders and files recursively of each folder. However, there is a limit on how many items can be counted. If the limit is reached, an extra property '''overflow''' will be returned as well. If "shallow" is specified, the API returns the '''byte_count''' of files immediately inside each folder (non-recursive).
• response_format : 'xml' or 'json' (default 'xml')

Search

Description : Searches the the content of a given folder. If folder_key is not passed, then the search will be performed on the root folder ("myfiles"). In this case, the session token will be required. To search the root folder on devices other than the cloud, pass the device_id. If device_id is '-1', then a global search on all devices will be performed.

Required Parameters:

• search_text : The search keywords to look for in filenames, folder names, descriptions and tags.
• folder_key : Identify the folderkey of the folder to search. If not passed, the session token is then required, and the search will be performed on the root folder or the entire device according to search_all parameter.

• session_token : A type 1 or type 2 session token. (Type 2 will require a call signature). Needed only when accessing root folder, private folder, or the folder's private content.

• signature : This is the call signature that is required to authenticate a type 2 session token transaction.
• filter : filter by privacy and/or by filetype. This is a comma-separated list of file types and privacy options. Can take one or more of the following values : "public", "private", "image", "video", "audio", "document", "spreadsheet", "presentation", "application", "archive", "data", and "development".
• device_id : Specify which device to return the myfiles data. If not set, it defaults to the cloud. If it's set to -1, then search will be performed on all devices.
• search_all : 'yes' or 'no'. If folder_key is passed, then this parameter is ignored. If folder_key is not passed, search_all can be used to indicate whether to search the root folder only or the entire device (default 'yes').
• details: "yes", "no", or "shallow" ("no" by default). If "yes", the API returns the '''total_files''', '''total_folders''', and '''total_size''' for all the contained folders and files recursively of each folder. However, there is a limit on how many items can be counted. If the limit is reached, an extra property '''overflow''' will be returned as well. If "shallow" is specified, the API returns the '''byte_count''' of files immediately inside each folder (non-recursive).
• response_format : 'xml' or 'json' (default 'xml')
