CLI / HTTP client for myDATA

This project allows users to interact with myDATA ("my Digital Accounting and Tax Application") either via a Python HTTP client or from the CLI.

Install

Install it with pip:

python -m pip install mydata-client

Usage

[!WARNING] The tool is not suitable yet for production use. We strongly suggest that you use it for experimenting only with the development sandbox that myDATA provides.

[!NOTE] Oh, you may also find the docs a bit... lacking :grimacing:

If you want to interact programmatically with myDATA's API, you can use the HTTP client under mydata/client.py. The Python dataclasses that bind to XML documents can be found in the mydata/models* modules, depending on which version of the API you want to use.

There is also a proof-of-concept CLI that you can use:

mydata --username <username> <command>

There are two command groups that you can invoke:

• The api command group, which is unopinionated and straight up hits the endpoint that you ask.
• The invoice command group, which is heavily opinionated and adds some helper commands to work with invoices. Basically, it's there to assist the list -> retrieve -> copy -> edit -> validate -> send lifecycle of an invoice.

Building

Install uv. Then, install the project dependencies:

uv install

Adding new XSD schemas

Whenever there's an API update, myDATA devs include the XML schemas for the latest API. You can include them in the project as follows:

• Download the XSD zipfile from the myDATA page, and take note of its version number (e.g., 1.0.10).

• Run the following command:

  uv run ingest-xsd --api-version 1.0.10 /path/to/xsd.zip
  

• Commit the final result
