nova-post 0.2.2

Python SDK for working with the Nova Post API

Nova_Post

A Python wrapper for the Nova Poshta API, providing an easy-to-use interface for interacting with Nova Poshta's logistics and tracking services.

Features

• Address management: create, update, delete addresses, and retrieve city, warehouse, and street directories.
• Counterparty management: manage sender/receiver contacts and related information.
• Internet document (waybill) management: create, update, delete, and track shipments.
• Common API methods: retrieve time intervals, cargo types, packaging options, and service types.
• Shipment tracking: track parcels via document numbers and phone numbers.

Installation

You can install Nova_Post via pip:

pip install nova-post

Usage

Initialization

from nova_post.api import NovaPostApi

api = NovaPostApi(api_key="your_api_key")

Note: You can obtain your API key from your business account at Nova Poshta Business Cabinet.

Address API

from nova_post.models.address import GetCitiesRequest

request_data = GetCitiesRequest(FindByString="Київ", Limit=5)
cities = api.address.get_cities(request_data)
print(cities)

Shipment Tracking

from nova_post.models.tracking import TrackingRequest

tracking_request = TrackingRequest(DocumentNumber="20400048799000")
tracking_info = api.tracking.track_parcel(tracking_request)
print(tracking_info)

Creating a Waybill (Internet Document)

from nova_post.models.internet_document import SaveInternetDocumentRequest

request = SaveInternetDocumentRequest(
    PayerType="Sender",
    PaymentMethod="Cash",
    DateTime="2025-03-18",
    CargoType="Cargo",
    Weight=5.0,
    ServiceType="WarehouseWarehouse",
    SeatsAmount=1,
    Description="Test Cargo",
    Cost=500,
    CitySender="sender_city_ref",
    Sender="sender_ref",
    SenderAddress="sender_address_ref",
    ContactSender="contact_sender_ref",
    SendersPhone="contact_sender_phone",
    CityRecipient="recipient_city_ref",
    Recipient="recipient_ref",
    RecipientAddress="recipient_address_ref",
    ContactRecipient="contact_recipient_ref",
    RecipientsPhone="contact_recipient_phone"
)

document = api.internet_document.save_internet_document(request)
print(document)

Note: To determine Sender, Recipient, and their parameters (ref, address, etc.), use the counterparty adapter.

Documentation: All adapters follow the official Nova Poshta API documentation: Nova Poshta API Documentation.

Issues: Report bugs or suggest features at GitHub Issues.

Error Handling

Nova_Post raises NovaPostApiError when the API returns an error or when a request fails due to timeouts or invalid responses. Example:

from nova_post.exceptions import NovaPostApiError

try:
    tracking_info = api.tracking.track_parcel(tracking_request)
    print(tracking_info)
except NovaPostApiError as e:
    print(f"API error occurred: {e}")

Logging

Nova_Post includes logging for API requests and responses. By default, logs are sent to the standard output. You can configure logging in logger.py to redirect logs to a file or another logging service:

import logging
from nova_post.logger import logger

logger.setLevel(logging.DEBUG)
file_handler = logging.FileHandler("nova_post.log")
logger.addHandler(file_handler)

Configuration

Nova_Post supports optional configurations such as request timeouts and retries. These settings can be adjusted within the NovaPostApi class:

api = NovaPostApi(api_key="your_api_key")
api.DEFAULT_TIMEOUT = 15  # Increase timeout to 15 seconds

Supported Python Versions

Nova_Post is compatible with Python 3.9 and above.

Running Tests

To run unit and integration tests, use:

pytest tests/

Environment Variables

The library uses an API key, which should be set as an environment variable:

export NOVA_POST_API_KEY="your_api_key"

Planned Performance Improvements

To enhance performance, caching mechanisms will be introduced to store frequently used API responses (e.g., city directories and service lists). This will reduce redundant API calls and improve response times. Additional optimizations include connection pooling for HTTP requests.
