pyfortnox

Fortnox API V3 library client for Python

Installation

pyfortnox package can be installed either via pip or easy_install:

$ pip install --upgrade pyfortnox

$ easy_install --upgrade pyfortnox

You can install from the source code as well. First clone the repo and then execute:

$ python setup.py install

After installing, import pyfortnox package:

import fortnox

Usage

import fortnox

Build a client

Using this api without authentication gives an error

# Then we instantiate a client (as shown below)
client = fortnox.Client(
    access_token='<YOUR_PERSONAL_ACCESS_TOKEN>',
    client_secret='<YOUR_APPS_CLIENT_SECRET>'
)

Client Options

The following options are available while instantiating a client:

access_token: Personal access token
client_secret: Private/public integration app's client secret
base_url: Base url for the api
timeout: Request timeout
verbose: Verbose/debug mode

Architecture

The library follows few architectural principles you should understand before digging deeper.

Interactions with resources are done via service objects.
Service objects are exposed as properties on client instances.
Service objects expose resource-oriented actions.
Actions return dictionaries that support attribute-style access, a la JavaScript (thanks to Bunch and it's form Munch).

For example, to interact with projects API you will use fortnox.ProjectService, which you can get if you call:

client = fortnox.Client(
    access_token='<YOUR_PERSONAL_ACCESS_TOKEN>',
    client_secret='<YOUR_APPS_CLIENT_SECRET>'
)
client.projects # fortnox.ProjectService

To retrieve list of resources and use filtering you will call list() method:

client = fortnox.Client(
    access_token='<YOUR_PERSONAL_ACCESS_TOKEN>',
    client_secret='<YOUR_APPS_CLIENT_SECRET>'
)
client.projects.list(organization_id=google.id, hot=True) # list(dict|Munch)

or simply client.projects.list()

To find custom field by name and its value pass kwargs as an argument:

client = fortnox.Client(
    access_token='<YOUR_PERSONAL_ACCESS_TOKEN>',
    client_secret='<YOUR_APPS_CLIENT_SECRET>'
)
client.projects.list(**{'ProjectNumber': 1})

To find a resource by its unique identifier use retrieve() method:

client = fortnox.Client(
    access_token='<YOUR_PERSONAL_ACCESS_TOKEN>',
    client_secret='<YOUR_APPS_CLIENT_SECRET>'
)
client.projects.retrieve(id=1)

When you'd like to create a resource, or update it's attributes you want to use either create() or update() methods. For example if you want to create a new project you will call:

client = fortnox.Client(
    access_token='<YOUR_PERSONAL_ACCESS_TOKEN>',
    client_secret='<YOUR_APPS_CLIENT_SECRET>'
)
project = client.projects.create(Description='Website design', Status='ONGOING')

project.ProjectNumber = 1
project.Status = 'ONGOING'
project.Description = 'Website redesign'

client.projects.update(project.ProjectNumber, StartDate='2014-02-28')

To destroy a resource use destroy() method:

client = fortnox.Client(
    access_token='<YOUR_PERSONAL_ACCESS_TOKEN>',
    client_secret='<YOUR_APPS_CLIENT_SECRET>'
)
client.projects.destroy(project.ProjectNumber)

There other non-CRUD operations supported as well. Please contact corresponding service files for in-depth documentation.

Full example

# Obtain an access token using a new authorization code. This access token will
# then be used for any further API calls.
client = fortnox.Client(
    authorization_code='<YOUR_APP_INTEGRATION_AUTHORIZATION_CODE>',
    client_secret='<YOUR_APPS_CLIENT_SECRET>'
)
obtained_token = client.token.client.token.access_token()
access_token = obtained_token.AccessToken

Handling Exceptions

When you instantiate a client or make any request via service objects, exceptions can be raised for multiple of reasons e.g. a network error, an authentication error, an invalid param error etc.

Sample below shows how to properly handle exceptions:

try:
    # Instantiate a client.
    client = fortnox.Client(
        access_token='<YOUR_PERSONAL_ACCESS_TOKEN>',
        client_secret='<YOUR_APPS_CLIENT_SECRET>'
    )
    project = client.projects.create(Description='Website design', Status='ONGOING')
    print(project)
except fortnox.ConfigurationError as e:
    #  Invalid client configuration option
    pass
except fortnox.ResourceError as e:
    # Resource related error
    print('Http status = ' + e.http_status)
    print('Request ID = ' + e.logref)
    for error in e.errors:
        print('field = ' + error.field)
        print('code = ' + error.code)
        print('message = ' + error.message)
        print('details = ' + error.details)
except fortnox.RequestError as e:
    # Invalid query parameters, authentication error etc.
    pass
except Exception as e:
    # Other kind of exceptioni, probably connectivity related
    pass

Sample below shows how to send files via inbox service with handled exceptions:

try:
    # Instantiate a client.
    client = fortnox.Client(
        access_token='<YOUR_PERSONAL_ACCESS_TOKEN>',
        client_secret='<YOUR_APPS_CLIENT_SECRET>'
    )
    
    from io import BytesIO
    file =  open('/your/local/file/path/voucher_file.jpeg', 'rb')
    
    buffered_file = BytesIO(file.read())
    file_name = 'voucher1.jpg'
    
    voucher_file = client.inbox.create(path='inbox_v', file=buffered_file, file_name=file_name)
    
    print(voucher_file)
except fortnox.ConfigurationError as e:
    #  Invalid client configuration option
    pass
except fortnox.ResourceError as e:
    # Resource related error
    print('Http status = ' + e.http_status)
    print('Request ID = ' + e.logref)
    for error in e.errors:
        print('field = ' + error.field)
        print('code = ' + error.code)
        print('message = ' + error.message)
        print('details = ' + error.details)
except fortnox.RequestError as e:
    # Invalid query parameters, authentication error etc.
    pass
except Exception as e:
    # Other kind of exceptioni, probably connectivity related
    pass

Resources and actions

Documentation for every action can be found under fortnox/services/ files.

Tests

To run all test suites:

$ python setup.py test

And to run a single suite:

$ python setup.py test -s fortnox.test.test_associated_project_service.ProjectServiceTests

Thanks

I would like to give huge thanks to my wife, fellow colleagues, mentors and friends for their continuous inspiration and supports to contribute to this package. pyfortnox was named from pythonic fortnox and I was lucky to publish wrapper under pyfortnox name.

Thank You!
