​
Overview

The ParityDeals Python SDK provides a convenient way to interact with the ParityDeals REST APIs from your Python application. The SDK supports both synchronous and asynchronous operations.

​
Installation

To install the ParityDeals SDK in your environment, run the following command: 
pip install paritydeals-sdk

​
Prerequisites

Before you can initialize the client and use the SDK methods, you need a Server API Key. You can obtain this key from the ParityDeals application:
  1. Navigate to Settings.
  2. Go to the Developers section.
  3. Copy the Server API Key.
Once copied, add this key to your environment variables or directly in your code (though environment variables are recommended for security). 
# Example of setting it in your code (ensure you handle this securely)
ACCESS_TOKEN = "__YOUR_API_KEY__"

​
Configuring the Client

The SDK supports both synchronous and asynchronous clients. The primary difference lies in how you create the client instance. Once created, both client types can invoke the same methods to communicate with the ParityDeals application.

​
How to Create a Synchronous Client

Use the synchronous client for traditional, blocking I/O operations. 
from paritydeals_sdk import ParityDeals

client = ParityDeals.create_sync_client(access_token=ACCESS_TOKEN)

​
How to Create an Asynchronous Client

Use the asynchronous client for non-blocking I/O operations, suitable for applications using asyncio. 
from paritydeals_sdk import ParityDeals

async_client = ParityDeals.create_async_client(access_token=ACCESS_TOKEN)

​
Supported Functionalities

The SDK currently supports the following operations:
  1. Customers
  2. Checkout
  3. Entitlements
  4. Reporting
  5. Subscriptions
Further details on each method, including parameters and return values, should be added under each functionality.

​
Customers

The customers module allows you to manage customer records within ParityDeals. You can access these operations via the customers attribute on an initialized ParityDeals client instance. All methods are available in both synchronous and asynchronous versions, depending on how the ParityDeals client was instantiated.

​
Creates a new customer

Synchronous: 
new_customer = client.customers.create(
    customerId="unique-customer-id-123",
    email="new.customer@example.com",
    name="John Doe",
    metadata={"source": "sdk_import", "priority": "high"}
)
print(f"Customer Created: ID = {new_customer.id}, Customer Client ID = {new_customer.customerId}")
Asynchronous: 
new_customer = await async_client.customers.create(
    customerId="unique-customer-id-456",
    email="another.new.customer@example.com",
    name="Jane Roe"
)
print(f"Customer Created (Async): ID = {new_customer.id}, Customer Client ID = {new_customer.customerId}")

{
  "id": "a1b2c3d4-e5f6-7890-1234-567890abcdef", // Server-generated UUID

Asynchronous: 
    updated_customer = await async_client.customers.update(
        customerId="unique-customer-id-456",
        email="jane.roe.updated@example.com"
    )
    print(f"Customer Updated (Async): {updated_customer.email}")

{
  "id": "a1b2c3d4-e5f6-7890-1234-567890abcdef", // Server-generated UUID

​
Entitlements

The entitlements module allows you to check and retrieve customer entitlements for various features. These operations target a specific edge API endpoint (https://edge.api.paritydeals.com by default) and use the GET HTTP method with query parameters.

​
Checks if a specific customer has access to a particular feature.

This method directly returns a boolean indicating access status. Synchronous: 
has_feature_access = client.entitlements.has_access(
    customerId="cust_123",
    featureId="premium-reporting"

​
Using the Sandbox Environment

The SDK can connect to the ParityDeals sandbox environment, which is perfect for testing and development. All operations performed in the sandbox are isolated and will not affect your live production data. To use the sandbox, simply pass the argument environment="sandbox" when creating the client.

​
How to Create a Synchronous Client (Sandbox)

from paritydeals_sdk import ParityDeals

# Note the 'environment' parameter
client = ParityDeals.create_sync_client(
    access_token=ACCESS_TOKEN,
    environment="sandbox"
)
The sandbox environment is completely separate from production. You will need to use a different set of API keys, and any data created (customers, subscriptions, etc.) will only exist in the sandbox.
