Authlete Library for Python
===========================

Overview
--------

This is the official Python library for [Authlete](https://www.authlete.com/)
Web APIs.

License
-------

  Apache License, Version 2.0

Source Code
-----------

  <code>https://github.com/authlete/authlete-python</code>

PyPI (Python Package Index)
---------------------------

  <code>https://pypi.org/project/authlete/</code>

Install
-------

    pip install authlete

Quick Start
-----------

The following code simulates "Authorization Code Flow". Replace `CLIENT_ID`,
`SERVICE_API_KEY` and `SERVICE_API_SECRET` in the code with your own properly.
The code assumes that the client type of the client application is 'public'
(otherwise client authentication would be required at the token endpoint) and
the number of registered redirect URIs is one (otherwise `redirect_uri` request
parameter would be required).

```python
from authlete.api  import *
from authlete.conf import *
from authlete.dto  import *


#--------------------------------------------------
# Your Configuration
#--------------------------------------------------
authlete_api_server = 'https://api.authlete.com'
service_api_key     = 'SERVICE_API_KEY'
service_api_secret  = 'SERVICE_API_SECRET'
client_id           = 'CLIENT_ID'
user_id             = 'USER_ID'


#--------------------------------------------------
# AuthleteApi
#--------------------------------------------------

# Configuration to access Authlete APIs.
cnf = AuthleteConfiguration()
cnf.baseUrl          = authlete_api_server
cnf.serviceApiKey    = service_api_key
cnf.serviceApiSecret = service_api_secret

# Authlete API caller
api = AuthleteApiImpl(cnf)


#--------------------------------------------------
# /api/auth/authorization API
#--------------------------------------------------

# Prepare a request to /api/auth/authorization API.
req = AuthorizationRequest()
req.parameters = 'response_type=code&client_id={}'.format(client_id)

# Call /api/auth/authorization API. The class of the
# response is authlete.dto.AuthorizationResponse.
res = api.authorization(req)


#--------------------------------------------------
# /api/auth/authorization/issue API
#--------------------------------------------------

# Prepare a request to /api/auth/authorization/issue API.
req = AuthorizationIssueRequest()
req.ticket  = res.ticket
req.subject = user_id

# Call /api/auth/authorization/issue API. The class of the
# response is authlete.dto.AuthorizationIssueResponse.
res = api.authorizationIssue(req)

# An authorization response returned to the user agent.
print('HTTP/1.1 302 Found')
print('Location: {}'.format(res.responseContent))


#--------------------------------------------------
# /api/auth/token API
#--------------------------------------------------

# Prepare a request to /api/auth/token API.
req = TokenRequest()
req.parameters = 'client_id={}&grant_type=authorization_code&code={}'\
    .format(client_id, res.authorizationCode)

# Call /api/auth/token API. The class of the response is
# authlete.dto.TokenResponse.
res = api.token(req)

# A token response returned to the client.
print("\nHTTP/1.1 200 OK")
print("Content-Type: application/json\n")
print(res.responseContent)
```

Description

#### How To Get AuthleteApi

All the methods to communicate with Authlete Web APIs are gathered in
`authlete.api.AuthleteApi` interface. `authlete.api.AuthleteApiImpl` class is
the only implementation of the interface. The constructor of `AuthleteApiImpl`
class requires an instance of `authlete.conf.AuthleteConfiguration` class.

```python
# Prepare an instance of AuthleteConfiguration.
cnf = AuthleteConfiguration()
cnf.baseUrl               = ...
cnf.serviceOwnerApiKey    = ...
cnf.serviceOwnerApiSecret = ...
cnf.serviceApiKey         = ...
cnf.serviceApiSecret      = ...

# Get an implementation of AuthleteApi interface.
api = AuthleteApiImpl(cnf)
```

`AuthleteConfiguration` class has two subclasses, `AuthleteEnvConfiguration`
and `AuthleteIniConfiguration`.

`AuthleteEnvConfiguration` class reads settings from the following environment
variables.

- `AUTHLETE_BASE_URL`
- `AUTHLETE_SERVICEOWNER_APIKEY`
- `AUTHLETE_SERVICEOWNER_APISECRET`
- `AUTHLETE_SERVICE_APIKEY`
- `AUTHLETE_SERVICE_APISECRET`

The constructor of `AuthleteEnvConfiguration` reads the environment variables,
so what you have to do in Python code is just to create an instance of the
class as follows.

```python
cnf = AuthleteEnvConfiguration()
```

On the other hand, `AuthleteIniConfiguration` class reads an INI file. The
format of the file `AuthleteIniConfiguration` expects is as follows.

```ini
[authlete]
base_url                 = ...
service_owner.api_key    = ...
service_owner.api_secret = ...
service.api_key          = ...
service.api_secret       = ...
```

The constructor of `AuthleteIniConfiguration` accepts an optional parameter
which represents the name of an INI file. If the parameter is omitted,
`authlete.ini` is used as the default file. If the name of your INI file is
not `authlete.ini`, pass the file name to the constructor explicitly as follows.

```python
cnf = AuthleteIniConfiguration('configuration.ini')
```

#### AuthleteApi Settings

`getSettings()` method of `AuthleteApi` interface returns an instance of
`authlete.api.Settings` class. You can set connection timeout and read timeout
via the instance.

```python
settings = api.getSettings()
settings.connectionTimeout = 5.0
settings.readTimeout       = 5.0
```

- UK Open Banking Security Profile

Features available in Authlete 2.1 and onwards:

- Client Initiated Backchannel Authentication (CIBA)
- JWT Secured Authorization Response Mode for OAuth 2.0 (JARM)
- Dynamic Client Registration (RFC 7591 & RFC 7592)
- OAuth 2.0 Device Authorization Grant (Device Flow)
- JWT-based Access Token
