myonlinestore-connect 1.0.2

Python client SDK for the MyOnlineStore Connect API

MyOnlineStore Connect API — Python Client

A typed Python SDK for the MyOnlineStore Connect API, providing sync and async access to all API endpoints with Pydantic-validated models.

PyPI package name: myonlinestore-connect Python import name: myonlinestore

Installation

pip install myonlinestore-connect

Then import it in Python with:

import myonlinestore

Or install from source:

pip install -e .

Quick start

from myonlinestore import ConnectClient

client = ConnectClient(
    store_token="your-store-token",
    partner_token="your-partner-token",  # optional
)

# List articles
page = client.articles.list(limit=20)
for article in page.items:
    print(f"{article.name} — {article.price}")

# Get a single order
order = client.orders.get(order_number=12345)
print(order.debtor.email)

client.close()

Async usage

Every method has an async counterpart prefixed with a:

import asyncio
from myonlinestore import ConnectClient

async def main():
    async with ConnectClient(store_token="your-token") as client:
        page = await client.articles.alist(limit=50)
        order = await client.orders.aget(order_number=12345)

asyncio.run(main())

Pagination

List endpoints return a PaginatedResponse with built-in page tracking:

page = client.articles.list(limit=100, offset=0)
print(page.has_next)     # True if more pages exist
print(page.next_offset)  # offset for the next page

To iterate all items automatically:

from myonlinestore.pagination import iterate_all

for article in iterate_all(client.articles.list, page_size=100):
    process(article)

Async iteration:

from myonlinestore.pagination import aiterate_all

async for article in aiterate_all(client.articles.alist, page_size=100):
    await process(article)

Available resources

Resource	Accessor	Key methods
Articles	client.articles	list, get, create, update, delete, count, upload_image, delete_image
Orders	client.orders	list, get, create, update, count, create_credit, list_payments, create_payment, create_payment_raw, update_payment, delete_payment
Customers	client.customers	list, get, create, update, delete, list_addresses, get_address, create_address, update_address, delete_address
Categories	client.categories	list, get, create, update, count, list_articles
Discount codes	client.discount_codes	list, get, create, update, delete
Newsletter	client.newsletter	list, get, create, update, delete, count
Order statuses	client.order_statuses	list
Payment gateways	client.payment_gateways	list, list_for_store
Shipping methods	client.shipping_methods	list
Store info	client.store	get
Offline locations	client.offline_locations	list, get
Tax policy	client.tax_policy	list, get
Article fields	client.article_fields	create, delete
Article lists	client.article_lists	get, add, remove
Article list options	client.article_list_options	create, delete

Note: list_articles on categories returns ArticleLimited objects (id, name, uuid, is_main only). create_payment_raw returns the full API response dict including the payment redirect URL.

Configuration

from myonlinestore import ConnectClient, ConnectConfig

config = ConnectConfig(
    store_token="xxx",
    partner_token="yyy",
    api_version="1",            # "1" (stable) or "2-beta"
    language="en_GB",            # response language
    timeout=60.0,                # default timeout (seconds)
    connect_timeout=5.0,         # TCP connect timeout
    read_timeout=30.0,           # response read timeout
    pool_timeout=30.0,           # pool acquire timeout
    max_connections=100,         # connection pool size
    max_keepalive=20,            # keep-alive connections
    default_limit=50,            # default page size
    max_retries=3,               # retry attempts (0 to disable)
    max_retry_delay=60.0,        # cap on retry backoff (seconds)
    idempotency_key_header="Idempotency-Key",  # None to disable
)

client = ConnectClient(config=config)

Retry and resilience

The SDK automatically retries on transient errors (429, 500, 502, 503, 504, and connection/timeout errors) using exponential backoff with full jitter:

delay = random(0, min(max_retry_delay, 0.5 * 2^attempt))

Key behaviors:

• Retry-After headers are respected on 429 responses (both numeric seconds and HTTP-date formats).
• POST and PATCH are only retried when idempotency keys are enabled, preventing duplicate mutations.
• Idempotency keys are auto-injected as UUIDs on POST/PATCH requests via the Idempotency-Key header.
• Set max_retries=0 to disable retries entirely.

Error handling

All API errors raise typed exceptions:

from myonlinestore import (
    ConnectError,         # base class
    AuthenticationError,  # 401/403
    NotFoundError,        # 404
    ValidationError,      # 422
    RateLimitError,       # 429 (includes retry_after attribute)
    ServerError,          # 5xx
)

try:
    article = client.articles.get(article_id=99999)
except NotFoundError:
    print("Article not found")
except RateLimitError as e:
    print(f"Rate limited — retry after {e.retry_after}s")
except AuthenticationError:
    print("Check your API token")

All exceptions carry status_code, body, and a compact __repr__ for logging.

Logging

The SDK logs via Python's standard logging module under the "myonlinestore" logger:

import logging

logging.basicConfig(level=logging.DEBUG)
logging.getLogger("myonlinestore").setLevel(logging.DEBUG)

Log levels used:

• DEBUG — request method, URL, and (redacted) params
• INFO — retries, rate-limit pauses, Retry-After delays

Auth tokens are automatically redacted in all log output.

API version support

The SDK defaults to API v1. To use the v2-beta:

client = ConnectClient(store_token="xxx", api_version="2-beta")

Type safety

The SDK is fully typed with PEP 561 support (py.typed marker included). All models use Pydantic v2 with:

• snake_case Python fields with camelCase aliases for API compatibility
• extra="ignore" to silently drop unknown fields (forward-compatible)
• Compact __repr__ on all models showing only non-None fields

Works out of the box with mypy, pyright, and IDE autocomplete.

Requirements

• Python 3.10+
• httpx >=0.24.0, <1.0
• pydantic >=2.0.0, <3.0
