exactpy 0.0.9

Modern Python interface to the exact online API

ExactPy

A modern, highly configurable Python interface to the Exact Online API based on Pydantic and httpx and offers support for conversion to Pandas DataFrames.

Installing

You can install directly from PyPI using e.g.

uv add exactpy

or

pip install exactpy

or you can install locally from file using:

uv pip install -e <location_on_disk>

Developing

This repo provides a devcontainer to easily develop the package. It assumes you have uv and fish installed on your host system. This cannot be made optional because these assumptions involve bind mounts.

Install the package locally (symlinked) within the venv created by uv using:

uv pip install -e .

Pre-commit

We use pre-commit to run a few hooks to ensure code quality and stuff like that. Please use the devcontainer, all this is taken care for you if you do so.

Running tests

We use tox for bothing running the tests as well as running pre-commit. Please run tox to run your tests.

Contributing

Please see CONTRIBUTING.md.

Issues

If you discover bugs or other issues, please create an issue with a stack trace and code to reproduce. We have no predefined format for issues, just make sure there is enough info to reproduce.

Why?

Currently available packages aren't configurable in such a way that they are usable to me. This package attempts to fix that.

Sample usage

Initial oauth token request

This initial token request theoretically needs to be done once. An access token and requets token will be available after this. If the access token is refreshed in time (refresh token is valid for 30 days max), no log in has to be performed.

from exactpy.client import Client

client_id = "***"
client_secret = "***"

# This can be anything, but it needs to satisfy two conditions:
# 1. It needs to be a valid public website
# 2. It needs to be website protected by an SSL certificate (https)
# It needs to match exactly what you entered in your app registration
redirect_url = "https://some_site"

client = Client(
    client_id=client_id, client_secret=client_secret, redirect_url=redirect_url
)

# This will print a link that you can click
# You'll have to log to the Exact Online portal first
# You'll get redirected to `redirect_url`, and you'll need to copy that url
print(client.auth_client.get_authorization_url())

# Enter the url that you've copied earlier and hit enter
resp_url = input()

# If everything went well, you should now be able to acquire
# a token and refresh token with the line below
# This will also automatically cache your credentials
# to file, if caching is enabled (which it is, by default)
client.auth_client.acquire_token(resp_url)

If your cache callable was not set to None, your credentials should now have been saved. In the default case, they're saved in creds.json (plain text).

Now you can use the client like below:

from exactpy.client import Client
from pprint import pprint

client = Client(
    client_id="xxx",
    client_Secret="xxx,
    verbose=True,
)

# (Almost) every request requires a division to be set
# This division number is set as a client property
# and set with every request, as part of the url
# You can set the division equal to the current divison
# (current as in server side) using:
client.set_initial_division()

# Print the division using:
pprint(client.get_current_division().model_dump(by_alias=True))

# Alternatively, you may pick a different division by listing them
# and selecting a specific one:
divisions = client.system.divisions.all()

# Select the "nth" division and set it as current division
# n = 0...len(divisions)-1
client.current_division = divisions[n].code

# Every request you do, will trigger a token
# check as well. In the default case, auto-caching is done
# This means that the current access token and refresh token
# (after a optional refresh) are cached. This is only true
# if cache_callable was not set to None.
# To disable this behaviour, either set cache_callable to None
# or set autocache_enabled to False.

# Note that endpoint controllers are namespaced by service,
# as shown below (general ledger accounts are part of the
# financial service) and above (divisions are part of the)
# system service
gl_accounts = client.financial.gl_accounts.all()
