python-appie 0.2.0

Unofficial Python client for the Albert Heijn API.

python-appie

python-appie is an unofficial async Python client for the Albert Heijn API.

Full documentation is available in English and Dutch. The source for the docs lives in docs/ and is built from mkdocs.yml.

Releases are intended to publish to PyPI as python-appie from version tags via GitHub Actions.

Install

uv add python-appie

Or:

pip install python-appie

For local development in this repository:

uv sync --extra dev
pre-commit install

Quick start

Authenticate once:

uv run appie-login

This opens Chrome for an interactive AH login and captures the OAuth redirect code automatically. If automatic capture cannot start, the CLI falls back to asking for the redirect URL or raw code manually.

Then use the client:

import asyncio

from appie import AHClient


async def main() -> None:
    async with AHClient() as client:
        products = await client.products.search("melk", limit=3)
        for product in products:
            print(product)


asyncio.run(main())

Tokens are stored in ~/.config/appie/tokens.json and refreshed automatically when they are close to expiring.

Features

Authentication

• appie-login CLI for browser-based login
• automatic code capture from the AH redirect flow
• token persistence in ~/.config/appie/tokens.json
• automatic token refresh using the stored refresh token

Products

• search products via client.products.search(query, limit=10)
• fetch a single product via client.products.get(product_id)

Example:

import asyncio

from appie import AHClient


async def main() -> None:
    async with AHClient() as client:
        product = await client.products.get(1525)
        print(product)


asyncio.run(main())

Receipts

• list in-store POS receipt summaries via client.receipts.list_all(limit=50)
• fetch a receipt with line items via client.receipts.get_pos_receipt(receipt_id)

Important: list_all() and list_pos_receipts() return receipt summaries. In those results, products is intentionally empty. To retrieve line items, call get_pos_receipt() with a receipt ID from the summary list.

Example:

import asyncio

from appie import AHClient


async def main() -> None:
    async with AHClient() as client:
        receipts = await client.receipts.list_all(limit=5)
        detailed = await client.receipts.get_pos_receipt(receipts[0].id)
        print(detailed)


asyncio.run(main())

Shopping lists

• add an item via client.lists.add_item(description, quantity=1, product_id=None)
• read the current shopping list via client.lists.get_list()
• remove one item via client.lists.remove_item(item_id)
• clear the entire list via client.lists.clear()
• use MockAHClient for local development and tests without touching AH

Example:

import asyncio

from appie import AHClient


async def main() -> None:
    async with AHClient() as client:
        await client.lists.add_item("Halfvolle melk", quantity=2)
        items = await client.lists.get_list()
        print(items)


asyncio.run(main())

Note: the ShoppingListItem.id returned by get_list() is an opaque removal key designed for remove_item(item_id). It should be treated as an implementation detail rather than a stable AH server identifier.

Mocking and downstream tests

• MockAHClient() provides an in-memory drop-in client for local development
• client.mock.calls and client.mock.last_call capture what your code did
• client.mock.next_response(operation, value) seeds a one-shot result
• client.mock.next_error(operation, exc) seeds a one-shot failure
• client.mock.set_scenario(operation, delay_ms=..., error=...) applies persistent delay/error behavior
• appie.pytest_plugin provides pytest fixtures for downstream packages

Example:

import asyncio

from appie import MockAHClient


async def main() -> None:
    async with MockAHClient() as client:
        client.mock.next_response("products.search", [])
        products = await client.products.search("melk")
        print(products)
        print(client.mock.last_call)


asyncio.run(main())

Expected outcome:

[]
AppieMockCall(operation='products.search', params={'query': 'melk', 'limit': 10}, result=[], error=None)

Pytest plugin example:

# tests/conftest.py
pytest_plugins = ["appie.pytest_plugin"]

import pytest


@pytest.mark.asyncio
async def test_checkout_uses_expected_query(appie_mock):
    await appie_mock.products.search("melk", limit=3)

    assert appie_mock.mock.last_call is not None
    assert appie_mock.mock.last_call.params == {"query": "melk", "limit": 3}

Expected outcome:

• the test runs without touching AH
• the recorded call proves what your code sent into python-appie

Notes

• This client is unofficial and may break when Albert Heijn changes its backend.
• Receipt support currently covers in-store POS receipts.
• Shopping-list read, add, remove, and clear are implemented against the live main-list endpoint.
• Receipt summaries do not include line items; call get_pos_receipt() for a detailed receipt.
• Endpoint discovery for this package is inspired by gwillem/appie-go.
