Key Features

• HMAC Authentication: Handles the complex HMAC authentication required by the 1WorldSync API.
• Easy-to-use Client: Provides a simple interface for interacting with the API.
• Data Models: Structured models for API responses, making it easier to work with the data.
• Error Handling: Custom exceptions for different types of errors.
• Examples: Ready-to-use example scripts demonstrating common use cases.

Installation

pip install oneworldsync

Or install from source:

git clone https://github.com/mcgarrah/oneworldsync_client.git
cd oneworldsync_python
pip install -e .

Development Installation

To install with development dependencies:

pip install -e ".[dev]"

Or using the requirements files:

pip install -r requirements-dev.txt

Authentication

The 1WorldSync API uses HMAC authentication. You'll need an App ID and Secret Key from 1WorldSync.

You can store these credentials in a .env file:

ONEWORLDSYNC_APP_ID=your_app_id
ONEWORLDSYNC_SECRET_KEY=your_secret_key
ONEWORLDSYNC_API_URL=1ws_api_endpoint

Important Note: The 1WorldSync API is very particular about the order of parameters in the authentication process. The parameters must be in a specific order when constructing the string to hash. This library handles this complexity for you, ensuring that parameters are ordered correctly for authentication.

Usage

Basic Usage

from oneworldsync import OneWorldSyncClient
import os
from dotenv import load_dotenv

# Load credentials from .env file
load_dotenv()
app_id = os.getenv("ONEWORLDSYNC_APP_ID")
secret_key = os.getenv("ONEWORLDSYNC_SECRET_KEY")

# Initialize client
client = OneWorldSyncClient(app_id, secret_key)

# Perform a free text search
results = client.free_text_search("milk")

# Print number of results
print(f"Found {len(results.products)} products")

# Print details of the first product
if results.products:
    product = results.products[0]
    print(f"Product: {product.brand_name} - {product.product_name}")
    print(f"Description: {product.description}")

Advanced Search

# Search for a product by UPC
results = client.advanced_search("itemIdentifier", "16241419122223")

# Search with geo location
results = client.free_text_search(
    "coffee",
    geo_location=(37.7749, -122.4194)  # San Francisco coordinates
)

Working with Products

# Get a specific product by ID
product_data = client.get_product("some_product_id")

# Access product attributes
for product in results.products:
    print(f"ID: {product.item_id}")
    print(f"Brand: {product.brand_name}")
    print(f"Name: {product.product_name}")
    print(f"Description: {product.description}")
    
    # Get product dimensions
    dimensions = product.dimensions
    if dimensions:
        print(f"Dimensions: {dimensions['height']['value']} {dimensions['height']['unit']} x "
              f"{dimensions['width']['value']} {dimensions['width']['unit']} x "
              f"{dimensions['depth']['value']} {dimensions['depth']['unit']}")
    
    # Get product images
    for image in product.images:
        print(f"Image URL: {image['url']} (Primary: {image['is_primary']})")

Error Handling

from oneworldsync import OneWorldSyncClient, AuthenticationError, APIError

try:
    client = OneWorldSyncClient(app_id, secret_key)
    results = client.free_text_search("apple")
except AuthenticationError as e:
    print(f"Authentication failed: {e}")
except APIError as e:
    print(f"API error: {e}")
    print(f"Status code: {e.status_code}")

Version Management

To update the version number across all files (oneworldsync/__init__.py, pyproject.toml, and setup.py), use the provided script:

# Update to version 0.1.4
python version_update.py 0.1.4

Troubleshooting

If you encounter authentication issues, check that:

1. Your ONEWORLDSYNC_APP_ID, ONEWORLDSYNC_SECRET_KEY and ONEWORLDSYNC_API_URL are correct and in sync.
2. You're using the correct environment (production vs. preprod) for your credentials.
3. Your system clock is synchronized (timestamp accuracy is important for authentication)

For API errors with status code 400, check the response message for details about which parameters might be invalid.
