capo-connecthealth: typed, async Python SDK for AWS Connecthealth

capo-connecthealth is a typed Python SDK for AWS Connecthealth. It has an async client, AsyncConnectHealthClient, for asyncio and trio, and a sync client, ConnectHealthClient, with the same methods. Requests and responses are typed with TypedDicts, so your editor and type checker know every field.

It is part of capo, a community-driven alternative to boto3 and aioboto3, built on its own HTTP stack instead of botocore and generated from the official AWS Smithy models. Documentation: https://capo-sdk.dev/services/connecthealth/

Installation

pip install capo-connecthealth

Usage

from capo_connecthealth import AsyncConnectHealthClient


async def main():
    async with AsyncConnectHealthClient() as connect_health:
        # Example: call the activate_subscription operation
        response = await connect_health.activate_subscription()
        print(response["subscription"])

Pagination

Some operations in this SDK support pagination. If the operation supports pagination it will have an iter_ prefixed method that returns an async iterator.

from capo_connecthealth import AsyncConnectHealthClient


async def main():
    async with AsyncConnectHealthClient() as connect_health:
        # Example: paginate over list_domains
        async for item in connect_health.iter_list_domains():
            print(item)

Streaming Request

Some operations accept a streaming request body. Pass an async iterator of bytes chunks, or the whole body as bytes, for the streaming parameter.

A plain iterator can be sent only once, so if a request fails after its body was transmitted the operation is not retried. To get retries for streamed uploads, pass a Body instead: it wraps a source that can be reopened, and every attempt streams a fresh copy. Body.from_path (sync client) and Body.async_from_path (async client, needs anyio) stream a file from disk; Body(opener) takes any context manager that yields a (stream, length) pair.

from capo_connecthealth import AsyncConnectHealthClient, Body


async def main():
    async with AsyncConnectHealthClient() as connect_health:
        # Example: call start_medical_scribe_listening_session with a streaming request body
        async def chunks():
            yield b'Hello, World!'

        response = await connect_health.start_medical_scribe_listening_session(input_stream=chunks())
        print(response)

        # Or pass the whole body as bytes
        response = await connect_health.start_medical_scribe_listening_session(input_stream=b'Hello, World!')
        print(response)

        # Or stream a file with Body: the file is reopened on every retry
        # and Content-Length is taken from its size, so no content_length needed
        response = await connect_health.start_medical_scribe_listening_session(input_stream=Body.async_from_path("hello.txt"))
        print(response)

Error Handling

The SDK raises exceptions for errors returned by the API. Catch them to handle failures gracefully.

from capo_connecthealth import AsyncConnectHealthClient
from capo_connecthealth.error import AccessDeniedException


async def main():
    async with AsyncConnectHealthClient() as connect_health:
        try:
            await connect_health.activate_subscription()
        except AccessDeniedException as e:
            print(f"Error: {e}")
            print(e.data)  # additional error data

Retrying

The SDK retries failed operations automatically. Retry behaviour follows the Smithy specification: errors are retried based on their is_retryable and is_throttling_error attributes. Throttling errors use a longer base delay. Network-level failures (connection errors and timeouts) are also retried. Non-retryable errors, such as client errors without the @retryable trait, are raised immediately without further attempts.

The number of attempts defaults to 3 and can be changed at the client level via retry_max_attempts, or per call via config_overrides.

from capo_connecthealth import AsyncConnectHealthClient


async def main():
    async with AsyncConnectHealthClient() as connect_health:
        # Default: 3 attempts for every operation
        response = await connect_health.activate_subscription()

        # Override per operation
        response = await connect_health.activate_subscription(config_overrides={"retry_max_attempts": 5})

        # Disable retries for this call
        response = await connect_health.activate_subscription(config_overrides={"retry_max_attempts": 1})
