Corbado Python SDK

The Corbado Python SDK provides convenient access to the Corbado Backend API from applications written in the Python language.

⚠️ The Corbado Python SDK is commonly referred to as a private client, specifically designed for usage within closed backend applications. This particular SDK should exclusively be utilized in such environments, as it is crucial to ensure that the API secret remains strictly confidential and is never shared.

🚀 Getting started

Requirements

• Python 3.8 or later

Installation

Use the following command to install the Corbado Python SDK:

pip install passkeys

Usage

To create a Corbado Python SDK instance you need to provide your Project ID and API secret which can be found at the Developer Panel.

config: Config = Config(project_id="{project_id}", api_secret="{api_secret}")
sdk = CorbadoSDK(config=config)

• Check integration tests here

🛠️ Services

The Corbado Python SDK provides the following services:

• sessions for managing sessions (example flask app)
• users for managing users (examples)
• identifiers for managing login identifiers (examples)

To use a specific service, such as users, invoke it as shown below:

user_service: UserService = sdk.users

Error handling

The Corbado Python SDK raises exceptions for all errors. The following exceptions are thrown:

• ValidationError for failed validations (client side)
• ServerException for server errors (server side)
• TokenValidationException for errors in session service (client side)
• StandardException for everything else (client side)

SessionService returns a UserEntity as a result of token validation. If the token is invalid for any reason, a TokenValidationException is thrown. It provides detailed information on the error. If no error, is thrown, the session_token is valid and you can use the UserEntity object.

try:
  user: UserEntity = sdk.sessions.validate_token(session_token)
except TokenValidationException:
  # handle error..
  pass

If the Backend API returns a HTTP status code other than 200, the Corbado Python SDK throws a ServerException. The ServerExceptionclass provides convenient methods to access all important data: sdk.users.get(user_id="usr-123456789")

        try:
            # Try to get non-existing user with ID 'usr-123456789'
            sdk.users.get(user_id="usr-123456789")
        except ServerException as e:
            # Show HTTP status code (404 in this case)
            print(f"Status Code: {e.http_status_code}")

            # Show request ID (can be used in developer panel to look up the full request
            # and response, see https://app.corbado.com/app/logs/requests)
            print(f"Request id: {e.request_id}")

            # Show full request data
            print(f"Request data: {e.request_data}")

            # Show runtime of request in seconds (server side)
            print(f"Runtime: {e.runtime}")

            # Show error type (not_found)
            print(f"Error type: {e.error_type}")

            # Show full error data
            print(f"Full error: {e.error}")

Developer Setup

Create a virtual environment and install packages -

python3 -m venv venv_name
source venv_name/bin/activate
pip install -r requirements-dev.txt

(Add venv_name to "exclude" list in .flake8, otherwise flake8 will lint the generated venv)

Add environment variables for tests (use the test project from secrets repositoty) -

export CORBADO_API_SECRET=corbado1_123456
export CORBADO_PROJECT_ID=pro-123456
export CORBADO_BACKEND_API="https://backendapi.cloud.corbado.io"

Testing

Run all tests using -

tox run -e py38

The tox tests are configured to run on Python 3.8, 3.9, 3.10, 3.11, 3.12 (you need to remove "-e py38" tox argument)

Run linting and mypy:

mypy -p corbado_python_sdk --exclude generated --strict --disable-error-code attr-defined
flake8 .

Development notes

Use Version file as single source of truth for version control.

Use VSCode with provided project/extentions configuration .vscode/settings.json

Use the recommended extentions from .vscode/extentions.json and explore their functionality to achieve expected code quality by integration tests:
