FlexPrice Python SDK

Type-safe Python client for the FlexPrice API: billing, metering, and subscription management for SaaS and usage-based products.

Requirements

• Python 3.10+

Installation

pip install flexprice-temp

With uv or poetry:

uv add flexprice-temp
# or
poetry add flexprice-temp

Quick start

Initialize the client with your server URL and API key, then ingest an event:

from flexprice_temp import Flexprice

with Flexprice(
    server_url="https://api.cloud.flexprice.io",
    api_key_auth="YOUR_API_KEY",
) as flexprice:
    # Ingest an event
    result = flexprice.events.ingest_event(
        request={
            "event_name": "Sample Event",
            "external_customer_id": "customer-123",
            "properties": {"source": "python_app", "environment": "test"},
            "source": "python_app",
        }
    )
    print(result)

Async usage

The same client supports async when used as an async context manager:

import asyncio
from flexprice_temp import Flexprice

async def main():
    async with Flexprice(
        server_url="https://api.cloud.flexprice.io",
        api_key_auth="YOUR_API_KEY",
    ) as flexprice:
        result = await flexprice.events.ingest_event_async(
            request={
                "event_name": "Sample Event",
                "external_customer_id": "customer-123",
                "properties": {"source": "python_async", "environment": "test"},
                "source": "python_async",
            }
        )
        print(result)

asyncio.run(main())

Authentication

• Pass your API key as api_key_auth when creating the client. The SDK sends it in the x-api-key header.
• Prefer environment variables (e.g. FLEXPRICE_API_KEY) and load them in code; get keys from your FlexPrice dashboard or docs.

Features

• Full API coverage (customers, plans, events, invoices, payments, entitlements, etc.)
• Sync and async support
• Type-safe request/response models (Pydantic)
• Built-in retries and error handling

For a full list of operations, see the API reference or the generated docs/sdks/ in this repo.

Troubleshooting

• Missing or invalid API key: Ensure api_key_auth is set (or set FLEXPRICE_API_KEY and pass it in). Keys are for server-side use only.
• Wrong server URL: Use https://api.cloud.flexprice.io (no trailing slash). The SDK appends paths as needed.
• 4xx/5xx on ingest: Event ingest returns 202 Accepted; for errors, check request fields (event_name, external_customer_id, properties, source) against the API docs.
