Files.fm Cloud File Storage API

We support WebDAV file management protocol and web GET/POST REST calls via https. Below are short version of initial steps, how to upload files to a specific user's storage via HTTP GET and POST requests. You have to create user account at first. (You can do "anonymous" uploads without login, but those will be valid 2 months maximum and are subjects to security limits.)

Quick manual (TLDR)

1) CREATE new folder via get_upload_id.php. This call returns the folder's HASH and EDIT and ADD keys. Hash is used to reference a folder or file: https://files.fm/u/zqrffeh or https://files.fm/f/$filehash

https://api.files.fm/api/get_upload_id.php?user=demo&pass=demo&folder_name=my_folder_name&access_type=LINK
The folder can be set private or accessible to anyone who knows the hash: access_type=PRIVATE|LINK

2) UPLOAD each file via HTTP POST to "save_file.php", providing target folder's hash and the corresponding Edit or Add key:

https://api.files.fm/save_file.php?up_id=trgkzgp&key=a3f8a&get_file_hash

Linux / Windows command line example for scripts:

curl -i -F 'file=@/tmp/local-file.txt' 'https://api.files.fm/save_file.php?up_id=hash&key=add_key'
curl -i -F 'file=@/tmp/local-file.txt' 'https://api.files.fm/save_file.php?up_id=jjqcank7&key=05123&get_file_hash'
Windows: curl -i -F file="@C:\temp\test.txt" "https://api.files.fm/save_file.php?up_id=jjqcank7&key=05123"
If file upload is successful, save_file.php will return file's hash (or letter 'd').
Files must be uploaded sequentially, one by one. This means, for each file that you want to upload, you must POST it to save_file.php

3) LIST folder contents by providing upload hash:

https://api.files.fm/api/get_file_list_for_upload.php?hash=polcdti

4) DOWNLOAD a particular file providing it's hash:

https://api.files.fm/down.php?i=jyphxsb

5) User login: create session ID token and cookies, get ROOT folder's keys: https://api.files.fm/api/login.php?user=demo&pass=demo
