• 🔍 Rich Observability: Built-in logging and metrics

🚀 Quick Start

Installation

# Clone the repository
git clone https://github.com/dougborg/katana-openapi-client.git
cd katana-openapi-client

# Install with Poetry (recommended)
poetry install

# Or with pip
pip install -e .

📋 Configuration

Create a .env file with your Katana API credentials:

KATANA_API_KEY=your-api-key-here
# Optional: defaults to https://api.katanamrp.com/v1
KATANA_BASE_URL=https://api.katanamrp.com/v1

Basic Usage

KatanaClient (Recommended)

The modern, pythonic client with automatic resilience:

import asyncio

from katana_public_api_client import KatanaClient
from katana_public_api_client.generated.api.product import get_all_products
from katana_public_api_client.generated.api.sales_order import get_all_sales_orders

async def main():
    # Automatic configuration from .env file
    async with KatanaClient() as client:
        response = await get_all_products.asyncio_detailed(
            client=client,
            limit=50
        )
        print(f"Status: {response.status_code}")
        print(f"Products: {len(response.parsed.data)}")

        # Automatic pagination happens transparently
        all_products_response = await get_all_products.asyncio_detailed(
            client=client,
            is_sellable=True
        )
        print(f"Total sellable products: {len(all_products_response.parsed.data)}")

        # Direct API usage with automatic resilience
        orders_response = await get_all_sales_orders.asyncio_detailed(
            client=client,
            status="open"
        )
        orders = orders_response.parsed.data if orders_response.parsed else []
        print(f"Open orders: {len(orders)}")

asyncio.run(main())

Generated Client (Direct)

For maximum control and custom resilience patterns:

import asyncio

from katana_public_api_client import AuthenticatedClient
from katana_public_api_client.generated.api.product import get_all_products

async def main():
    client = AuthenticatedClient(
        base_url="https://api.katanamrp.com/v1",
        token="your-api-key"
    )

    async with client:
        response = await get_all_products.asyncio_detailed(
            client=client,
            limit=50
        )
        if response.status_code == 200:
            products = response.parsed.data
            print(f"Found {len(products)} products")

asyncio.run(main())

📊 API Coverage

The client provides access to all major Katana functionality:

Category	Endpoints	Description
Products & Inventory	25+	Products, variants, materials, stock levels
Orders	20+	Sales orders, purchase orders, fulfillment
Manufacturing	15+	BOMs, manufacturing orders, operations
Business Relations	10+	Customers, suppliers, addresses
Configuration	6+	Locations, webhooks, custom fields

Total: 76+ endpoints with 150+ fully-typed data models.

🎯 Why KatanaClient?

Automatic Resilience

Every API call through KatanaClient automatically includes:

• Smart Retries: Exponential backoff for network errors and 5xx responses
• Rate Limit Handling: Automatic retry with Retry-After header support
• Error Recovery: Intelligent retry logic that doesn't retry 4xx client errors
• Observability: Rich logging for debugging and monitoring

Pythonic Design

# No decorators, no wrapper methods needed
async with KatanaClient() as client:
    # Just use the generated API methods directly
    response = await get_all_products.asyncio_detailed(
        client=client,
        limit=100
    )
    # Automatic retries, rate limiting, logging - all transparent!

Transport-Layer Architecture

Uses httpx's native transport layer for resilience - the most pythonic approach:

• Zero Dependencies: Built on httpx's standard extension points
• Maximum Compatibility: Works with any httpx-based code
• Easy Testing: Simple to mock and test
• Performance: Minimal overhead compared to decorators

🔧 Advanced Usage

Custom Configuration

import logging

from katana_public_api_client import KatanaClient

# Custom configuration
async with KatanaClient(
    api_key="custom-key",
    base_url="https://custom.katana.com/v1",
    timeout=60.0,
    max_retries=3,
    logger=logging.getLogger("katana")
) as client:
    # Your API calls here
    pass

Automatic Pagination

from katana_public_api_client import KatanaClient
from katana_public_api_client.generated.api.product import get_all_products

async with KatanaClient() as client:
    # Get all products with automatic pagination
    all_products_response = await get_all_products.asyncio_detailed(
        client=client,
        is_sellable=True
    )
    sellable_products = all_products_response.parsed.data
    print(f"Found {len(sellable_products)} sellable products")

Direct API Usage

from katana_public_api_client import KatanaClient
from katana_public_api_client.generated.api.inventory import get_all_inventory_points
from katana_public_api_client.generated.api.manufacturing_order import get_all_manufacturing_orders
from katana_public_api_client.generated.api.product import get_all_products, get_product
from katana_public_api_client.generated.api.sales_order import get_all_sales_orders, get_sales_order

async with KatanaClient() as client:
    # Direct API methods with automatic pagination and resilience
    products = await get_all_products.asyncio_detailed(
        client=client, is_sellable=True
    )
    orders = await get_all_sales_orders.asyncio_detailed(
        client=client, status="open"
    )
    inventory = await get_all_inventory_points.asyncio_detailed(
        client=client
    )
    manufacturing = await get_all_manufacturing_orders.asyncio_detailed(
        client=client, status="planned"
    )

    # Individual item lookup
    product = await get_product.asyncio_detailed(
        client=client, id=123
    )
    order = await get_sales_order.asyncio_detailed(
        client=client, id=456
    )
