formance-sdk-python

🏗 Welcome to your new SDK! 🏗

It has been generated successfully based on your OpenAPI spec. However, it is not yet ready for production use. Here are some next steps:

Summary

Formance Stack API: Open, modular foundation for unique payments flows

Introduction

This API is documented in OpenAPI format.

Authentication

Formance Stack offers one forms of authentication:

  • OAuth2 OAuth2 - an open protocol to allow secure authorization in a simple and standard method from web, mobile and desktop applications.

SDK Installation

Note

Python version upgrade policy

Once a Python version reaches its official end of life date, a 3-month grace period is provided for users to upgrade. Following this grace period, the minimum python version supported in the SDK will be updated.

The SDK can be installed with either pip or poetry package managers.

PIP

PIP is the default package installer for Python, enabling easy installation and management of packages from PyPI via the command line.

pip install formance-sdk-python

Poetry

Poetry is a modern tool that simplifies dependency management and package publishing by using a single pyproject.toml file to handle project metadata and dependencies.

poetry add formance-sdk-python

Shell and script usage with uv

You can use this SDK in a Python shell with uv and the uvx command that comes with it like so:

uvx --from formance-sdk-python python

It's also possible to write a standalone Python script without needing to set up a whole project like so:

#!/usr/bin/env -S uv run --script
# /// script
# requires-python = ">=3.9"
# dependencies = [
#     "formance-sdk-python",
# ]
# ///

from formance_sdk_python import SDK

sdk = SDK(
  # SDK arguments
)

# Rest of script here...

Once that is saved to a file, you can run it with uv run script.py where script.py can be replaced with the actual file name.

IDE Support

PyCharm

Generally, the SDK will work well with most IDEs out of the box. However, when using PyCharm, you can enjoy much better integration with Pydantic by installing an additional plugin.

SDK Example Usage

Example

# Synchronous Example
from formance_sdk_python import SDK
from formance_sdk_python.models import shared

with SDK(
    security=shared.Security(
        client_id="<YOUR_CLIENT_ID_HERE>",
        client_secret="<YOUR_CLIENT_SECRET_HERE>",
    ),
) as sdk:

    res = sdk.get_versions()

    assert res.get_versions_response is not None

    # Handle response
    print(res.get_versions_response)

The same SDK client can also be used to make asychronous requests by importing asyncio.

# Asynchronous Example
import asyncio
from formance_sdk_python import SDK
from formance_sdk_python.models import shared

async def main():
    async with SDK(
        security=shared.Security(
            client_id="<YOUR_CLIENT_ID_HERE>",
            client_secret="<YOUR_CLIENT_SECRET_HERE>",
        ),
    ) as sdk:

        res = await sdk.get_versions_async()

        assert res.get_versions_response is not None

        # Handle response
        print(res.get_versions_response)

asyncio.run(main())

Retries

Some of the endpoints in this SDK support retries. If you use the SDK without any configuration, it will fall back to the default retry strategy provided by the API. However, the default retry strategy can be overridden on a per-operation basis, or across the entire SDK.

To change the default retry strategy for a single API call, simply provide a RetryConfig object to the call:

from formance_sdk_python import SDK
from formance_sdk_python.models import shared
from formance_sdk_python.utils import BackoffStrategy, RetryConfig

with SDK(
    security=shared.Security(
        client_id="<YOUR_CLIENT_ID_HERE>",
        client_secret="<YOUR_CLIENT_SECRET_HERE>",
    ),
) as sdk:

    res = sdk.get_versions(,
        RetryConfig("backoff", BackoffStrategy(1, 50, 1.1, 100), False))

    assert res.get_versions_response is not None

    # Handle response
    print(res.get_versions_response)

If you'd like to override the default retry strategy for all operations that support retries, you can use the retry_config optional parameter when initializing the SDK:

from formance_sdk_python import SDK
from formance_sdk_python.models import shared
from formance_sdk_python.utils import BackoffStrategy, RetryConfig

with SDK(
    retry_config=RetryConfig("backoff", BackoffStrategy(1, 50, 1.1, 100), False),
    security=shared.Security(
        client_id="<YOUR_CLIENT_ID_HERE>",
        client_secret="<YOUR_CLIENT_SECRET_HERE>",
    ),
) as sdk:

    res = sdk.get_versions()

    assert res.get_versions_response is not None

    # Handle response
    print(res.get_versions_response)

Error Handling

Handling errors in this SDK should largely match your expectations. All operations return a response object or raise an exception.

By default, an API error will raise a errors.SDKError exception, which has the following properties:

Property Type Description
.status_code int The HTTP status code
.message str The error message
.raw_response httpx.Response The raw HTTP response
.body str The response content

When custom error responses are specified for an operation, the SDK may also raise their associated exceptions. You can refer to respective Errors tables in SDK docs for more details on possible exception types for each operation. For example, the add_metadata_on_transaction_async method may raise the following exceptions:

Error Type Status Code Content Type
errors.V2ErrorResponse default application/json
errors.SDKError 4XX, 5XX */*

Example

from formance_sdk_python import SDK
from formance_sdk_python.models import errors, shared

with SDK(
    security=shared.Security(
        client_id="<YOUR_CLIENT_ID_HERE>",
        client_secret="<YOUR_CLIENT_SECRET_HERE>",
    ),
) as sdk:
    res = None
    try:

        res = sdk.ledger.v2.add_metadata_on_transaction(request={
            "id": 1234,
            "ledger": "ledger001",
            "request_body": {
                "admin": "true",
            },
            "dry_run": True,
        })

        assert res is not None

        # Handle response
        print(res)

    except errors.V2ErrorResponse as e:
        # handle e.data: errors.V2ErrorResponseData
        raise(e)
    except errors.SDKError as e:
        # handle exception
        raise(e)

Server Selection

Select Server by Index

You can override the default server globally by passing a server index to the server_idx: int optional parameter when initializing the SDK client instance. The selected server will then be used as the default on the operations that use it. This table lists the indexes associated with the available servers:

# Server Variables Default values
0 http://localhost
1 https://{organization}.{environment}.formance.cloud environment: models.ServerEnvironment
organization: str		 "eu.sandbox"
"orgID-stackID"

If the selected server has variables, you may override their default values through the additional parameters made available in the SDK constructor.

Example

from formance_sdk_python import SDK
from formance_sdk_python.models import shared

with SDK(
    server_idx=1,
    security=shared.Security(
        client_id="<YOUR_CLIENT_ID_HERE>",
        client_secret="<YOUR_CLIENT_SECRET_HERE>",
    ),
) as sdk:

    res = sdk.get_versions()

    assert res.get_versions_response is not None

    # Handle response
    print(res.get_versions_response)

Override Server URL Per-Client

The default server can also be overridden globally by passing a URL to the server_url: str optional parameter when initializing the SDK client instance. For example:

from formance_sdk_python import SDK
from formance_sdk_python.models import shared

with SDK(
    server_url="http://localhost",
    security=shared.Security(
        client_id="<YOUR_CLIENT_ID_HERE>",
        client_secret="<YOUR_CLIENT_SECRET_HERE>",
    ),
) as sdk:

    res = sdk.get_versions()

    assert res.get_versions_response is not None

    # Handle response
    print(res.get_versions_response)

Custom HTTP Client

The Python SDK makes API calls using the httpx HTTP library. In order to provide a convenient way to configure timeouts, cookies, proxies, custom headers, and other low-level configuration, you can initialize the SDK client with your own HTTP client instance. Depending on whether you are using the sync or async version of the SDK, you can pass an instance of HttpClient or AsyncHttpClient respectively, which are Protocol's ensuring that the client has the necessary methods to make API calls. This allows you to wrap the client with your own custom logic, such as adding custom headers, logging, or error handling, or you can just pass an instance of httpx.Client or httpx.AsyncClient directly.

For example, you could specify a header for every request that this sdk makes as follows:

from formance_sdk_python import SDK
import httpx

http_client = httpx.Client(headers={"x-custom-header": "someValue"})
s = SDK(client=http_client)

or you could wrap the client with your own custom logic:

from formance_sdk_python import SDK
from formance_sdk_python.httpclient import AsyncHttpClient
import httpx

class CustomClient(AsyncHttpClient):
    client: AsyncHttpClient

    def __init__(self, client: AsyncHttpClient):
        self.client = client

    async def send(
        self,
        request: httpx.Request,
        *,
        stream: bool = False,
        auth: Union[
            httpx._types.AuthTypes, httpx._client.UseClientDefault, None
        ] = httpx.USE_CLIENT_DEFAULT,
        follow_redirects: Union[
            bool, httpx._client.UseClientDefault
        ] = httpx.USE_CLIENT_DEFAULT,
    ) -> httpx.Response:
        request.headers["Client-Level-Header"] = "added by client"

        return await self.client.send(
            request, stream=stream, auth=auth, follow_redirects=follow_redirects
        )

    def build_request(
        self,
        method: str,
        url: httpx._types.URLTypes,
        *,
        content: Optional[httpx._types.RequestContent] = None,
        data: Optional[httpx._types.RequestData] = None,
        files: Optional[httpx._types.RequestFiles] = None,
        json: Optional[Any] = None,
        params: Optional[httpx._types.QueryParamTypes] = None,
        headers: Optional[httpx._types.HeaderTypes] = None,
        cookies: Optional[httpx._types.CookieTypes] = None,
        timeout: Union[
            httpx._types.TimeoutTypes, httpx._client.UseClientDefault
        ] = httpx.USE_CLIENT_DEFAULT,
        extensions: Optional[httpx._types.RequestExtensions] = None,
    ) -> httpx.Request:
        return self.client.build_request(
            method,
            url,
            content=content,
            data=data,
            files=files,
            json=json,
            params=params,
            headers=headers,
            cookies=cookies,
            timeout=timeout,
            extensions=extensions,
        )

s = SDK(async_client=CustomClient(httpx.AsyncClient()))

Authentication

Per-Client Security Schemes

This SDK supports the following security scheme globally:

Name Type Scheme
client_id
client_secret		 oauth2 OAuth2 Client Credentials Flow

You can set the security parameters through the security optional parameter when initializing the SDK client instance. For example:

from formance_sdk_python import SDK
from formance_sdk_python.models import shared

with SDK(
    security=shared.Security(
        client_id="<YOUR_CLIENT_ID_HERE>",
        client_secret="<YOUR_CLIENT_SECRET_HERE>",
    ),
) as sdk:

    res = sdk.get_versions()

    assert res.get_versions_response is not None

    # Handle response
    print(res.get_versions_response)

Resource Management

The SDK class implements the context manager protocol and registers a finalizer function to close the underlying sync and async HTTPX clients it uses under the hood. This will close HTTP connections, release memory and free up other resources held by the SDK. In short-lived Python programs and notebooks that make a few SDK method calls, resource management may not be a concern. However, in longer-lived programs, it is beneficial to create a single SDK instance via a context manager and reuse it across the application.

from formance_sdk_python import SDK
from formance_sdk_python.models import shared
def main():
    with SDK(
        security=shared.Security(
            client_id="<YOUR_CLIENT_ID_HERE>",
            client_secret="<YOUR_CLIENT_SECRET_HERE>",
        ),
    ) as sdk:
        # Rest of application here...


# Or when using async:
async def amain():
    async with SDK(
        security=shared.Security(
            client_id="<YOUR_CLIENT_ID_HERE>",
            client_secret="<YOUR_CLIENT_SECRET_HERE>",
        ),
    ) as sdk:
        # Rest of application here...

Debugging

You can setup your SDK to emit debug logs for SDK requests and responses.

You can pass your own logger class directly into your SDK.

from formance_sdk_python import SDK
import logging

logging.basicConfig(level=logging.DEBUG)
s = SDK(debug_logger=logging.getLogger("formance_sdk_python"))

Development

Maturity

This SDK is in beta, and there may be breaking changes between versions without a major version update. Therefore, we recommend pinning usage to a specific package version. This way, you can install the same version each time without breaking changes unless you are intentionally looking for the latest version.

Contributions

While we value open-source contributions to this SDK, this library is generated programmatically. Feel free to open a PR or a Github issue as a proof of concept and we'll do our best to include it in a future release!
