Asynchronous Event Submission

The FlexPrice SDK provides asynchronous event submission functionality that allows you to:

• Submit events in a non-blocking manner with "fire-and-forget" capability
• Include optional callbacks to handle success/failure responses
• Automatically retry failed event submissions with exponential backoff
• Process events in background threads

Basic Async Usage

from flexprice import Configuration, ApiClient, EventsApi
from flexprice.models import DtoIngestEventRequest

# Configure the client
configuration = Configuration(api_key={'ApiKeyAuth': 'YOUR_API_KEY'})
configuration.host = "https://api.cloud.flexprice.io/v1"

# Create API client and event API instance
api_client = ApiClient(configuration)
events_api = EventsApi(api_client)

# Create an event
event = DtoIngestEventRequest(
    external_customer_id="customer123",
    event_name="api_call",
    properties={"region": "us-west", "method": "GET"},
    source="my_application"
)

# Submit asynchronously (fire-and-forget)
events_api.events_post_async(event)

Using Callbacks

# Define a callback function
def on_event_processed(result, error, success):
    if success:
        print(f"Event processed successfully: {result}")
    else:
        print(f"Event processing failed: {error}")

# Create and submit event with callback
event = DtoIngestEventRequest(
    external_customer_id="customer123",
    event_name="user_action",
    properties={"action": "login", "device": "mobile"},
    source="user_portal"
)

# Submit with callback
events_api.events_post_async(event, callback=on_event_processed)

Complete Example

For a complete example of asynchronous event submission, see the async_event_example.py file in the examples directory.

Running the Example

To run the provided example:

1. Clone the repository:

   git clone https://github.com/flexprice/python-sdk.git
   cd python-sdk/examples

2. Create a virtual environment and install dependencies:

   python -m venv venv
   source venv/bin/activate  # On Windows: venv\Scripts\activate
   pip install -r requirements.txt

3. Create a .env file with your API credentials:

   cp .env.sample .env
   # Edit .env with your API key

4. Run the example:

   python example.py

5. Run the async example:

   python async_event_example.py

Documentation

For detailed API documentation, refer to the code comments and the official FlexPrice API documentation.

Advanced Usage

Handling Errors

The SDK provides detailed error information through exceptions:

try:
    # API call
    result = client.some_api_call()
except flexprice.ApiException as e:
    print(f"API exception: {e}")
    print(f"Status code: {e.status}")
    print(f"Response body: {e.body}")
except Exception as e:
    print(f"General exception: {e}")

Asynchronous API Usage with asyncio

In addition to the built-in asynchronous event submission, the SDK can be used with libraries like asyncio for other operations:

import asyncio
import flexprice
from flexprice.api import customers_api

async def get_customer(customer_id):
    configuration = flexprice.Configuration(
        host="https://api.flexprice.io"
    )
    configuration.api_key['x-api-key'] = "your-api-key"
    
    async with flexprice.ApiClient(configuration) as api_client:
        api = customers_api.CustomersApi(api_client)
        return await api.customers_id_get(id=customer_id)

# Run with asyncio
customer = asyncio.run(get_customer("customer-123"))
print(customer)
