typsa-sso-client 0.2.2

Desktop Typsa SSO helper client for Lambda-based Microsoft auth flows.

SSO-Package-Pip

Package to integrate a desktop application with an existing Lambda-based SSO flow.

URL contract

This client builds the SSO trigger URL using only:

• email
• redirect_uri

Configuration (environment variables)

The library does not call load_dotenv(); your app can load a .env before calling TypsaSSOClient.set_config().

Authorize URL: The package includes the corporate SSO endpoint URL by default (DEFAULT_SSO_AUTHORIZE_URL in sso_typsa.defaults).
It is not mandatory to define SSO_AUTHORIZE_URL unless you want to override it (eg., another environment, staging, etc.).

Variable	Required	Purpose
SSO_AUTHORIZE_URL or TYPSA_SSO_AUTHORIZE_URL	No	Overrides the authorization URL embedded in the package
SSO_REDIRECT_URI, TYPSA_SSO_REDIRECT_URI, or SSO_CALLBACK_URL	No	Local callback URL (default: http://127.0.0.1:8765/callback)

See .env.example in this repository for optional overrides.

Example:

from sso_typsa import TypsaSSOClient

client = TypsaSSOClient.set_config()
tokens = client.authenticate_strict(email="[e-mail]")

Install (local development)

pip install -e .

Quick start

from sso_typsa import TypsaSSOClient

client = TypsaSSOClient(
    authorize_url="https://your-lambda-domain/sso",
    default_redirect_uri="http://127.0.0.1:8765/callback",
)

tokens = client.authenticate(email="[e-mail]")

print(tokens.id_token)
print(tokens.refresh_token)

What authenticate(...) does

• opens the browser to your Lambda SSO URL
• sends email and redirect_uri as query params
• waits for redirect callback on localhost
• returns parsed tokens

Separate desktop app entity

Desktop UI is now kept separate from the package in desktop_app/app.py.

Run from this repository:

pip install -e .
python desktop_app/app.py

This keeps desktop-sso-client as a clean reusable package, while the UI app is a consumer of that package.

Windows custom protocol registration (optional)

If you want browser to redirect directly to installed app, register your scheme in Windows. Example for scheme mydesktopapp:

reg add "HKCU\Software\Classes\mydesktopapp" /ve /d "URL:mydesktopapp Protocol" /f
reg add "HKCU\Software\Classes\mydesktopapp" /v "URL Protocol" /d "" /f
reg add "HKCU\Software\Classes\mydesktopapp\shell\open\command" /ve /d "\"python\" \"C:\path\to\desktop_app\app.py\" --callback-url \"%1\"" /f

After this, a redirect like mydesktopapp://auth/callback?... can open the app.

Web mapping

If web app uses:

const loginUrl = `${environment.ssoUrl}?email=${email}&redirect_uri=${redirectUri}`;
window.location.href = loginUrl;

desktop app equivalent:

tokens = client.authenticate(email="[e-mail]")
