SDK generator

One ready client file in C#, VB.NET, Python, JavaScript, Java, PHP, Dart or C++.

The SDK generator page writes a ready client for your program in one file, in C#, VB.NET, Python, JavaScript (Node.js), Java, PHP, Dart or C++. It already knows your server address and your app, so you add the file to your project and call it.

What the file can do

Call	What it does
Login, CheckKey	Sign in with a licence key (binds it to the machine), or only look a key up.
Heartbeat, RunHeartbeat	Keep the session alive. RunHeartbeat loops and calls you back when the key is banned, paused, expired, reset or signed out from the panel: close your app there.
Logout	End the session.
RegisterAccount, LoginAccount, ChangeAccountPassword	Customer accounts with a username and password, when accounts are on for the app.
GetAppInfo, GetTexts, GetSlides	The app's name, version and links, your texts and slides.
CheckUpdate	Asks Updates for a newer build.
CreateTrial, RequestHwidReset	A free trial for this machine (when trials are on), and a request to move a key to a new PC.

The names follow each language: LoginAsync in C# and VB.NET, login in Java and JavaScript, login and get_app_info in Python. The end of every file shows how to use it.

Using the page

Pick the language at the top, and the application.
Server address is always https://pwfauth.com; it cannot be changed.
Copy code or Download. Download all saves one file per language.
Install what the line under the settings says the language needs, for example pip install requests cryptography for Python.

The page remembers the language and the environment switch in this browser.

The app secret

The file contains your app secret, so treat it like a password: inside your compiled or obfuscated program, never in a public repository, a web page or a browser extension. With Read the secret from the environment on, the file reads the PWF_APP_SECRET environment variable instead and holds no secret, which is the way for open-source code and build servers. If a secret leaks, make a new one in Applications and generate the file again.

For C# and VB.NET the PWFAuth NuGet package is the easier way: fixes reach you as package updates, and it also checks that every reply was signed by this server. See C# and VB.NET.

Reading your texts

The second box shows how to read your texts in the same language: they come with the sign-in reply, and GetTexts reads them again at any time without signing in again.

How it talks to the server

Every request and reply is encrypted with AES-256 and signed with HMAC-SHA256, both keyed from your app secret, and a reply older than five minutes is refused. A file made before a change on the server keeps working; generate it again when this page shows something new you want to use. The first line of the file says when and for which app it was made.
