Rossum API

rossum-api provides Python programmatic access to the Rossum API and other useful tooling enabling seamless integration of the Rossum platform into Python applications.

It is a replacement for Rossum package. In case of any missing functionality, please open an issue or a pull request.

For comprehensive API reference and detailed examples, visit our documentation.

Note

If you need both synchronous and asynchronous API clients, this SDK provides both flavors to fit your application's needs.

Key Features

• Minimal dependencies: Lightweight with minimal external dependencies
• API-aligned naming: Method names map closely to the official API documentation
• Dual API support: Choose between synchronous and asynchronous clients
• Authentication: Built-in authentication handling
• Retry mechanism: Built-in retry mechanism handling throttling API errors
• Pagination handling: Automatically merges paginated results into one list
• Rich methods: Includes methods for frequent API operations
• Type-safe: Returns results as Python dataclasses with full type hints

Installation

The easiest way is to install the package from PyPI:

pip install rossum-api

or from the github repo:

pip install git+https://github.com/rossumai/rossum-sdk#egg=rossum-api

You can eventually download an installation file from GitHub releases and install it manually.

Usage

Python API

The rossum-api library can be used to communicate with Rossum API, instead of using requests library directly. The advantages of using rossum-api:

• it contains a function that merges the paginated results into a single list so the user does not need to get results page by page and take care of their merging,
• it comes with both synchronous and asynchronous API, so you can choose the approach you need,
• it takes care of authenticating the user,
• it includes many methods for common actions that you don't need to write by yourself from scratch,
• it returns the result as a Python first-class object (dataclass), so you don't need to parse the JSON by yourself,
• it maps method naming as close as possible to API docs,
• in case the API version changes, the change will be implemented in the library by the Rossum team for all users.
• it has minimal dependencies

Examples

You can choose between asynchronous and synchronous clients. Both are exactly the same in terms of features.

Async version

import asyncio
import os
from rossum_api import AsyncRossumAPIClient
from rossum_api.dtos import UserCredentials

WORKSPACE = {
    "name": "Rossum Client NG Test",
    "organization": "https://elis.rossum.ai/api/v1/organizations/116390",
}


async def main_with_async_client() -> None:
    client = AsyncRossumAPIClient(
        base_url="https://elis.rossum.ai/api/v1",
        credentials=UserCredentials(os.environ["ELIS_USERNAME"], os.environ["ELIS_PASSWORD"]),
    )
    ws = await client.create_new_workspace(data=WORKSPACE)
    workspace_id = ws.id
    ws = await client.retrieve_workspace(workspace_id)
    print("GET result:", ws)
    print("LIST results:")
    async for w in client.list_workspaces(ordering=["-id"], name=WORKSPACE["name"]):
        print(w)
    await client.delete_workspace(workspace_id)
    print(f"Workspace {workspace_id} deleted.")


asyncio.run(main_with_async_client())

Sync version

import os

from rossum_api import SyncRossumAPIClient
from rossum_api.dtos import UserCredentials

WORKSPACE = {
    "name": "Rossum Client NG Test",
    "organization": "https://elis.rossum.ai/api/v1/organizations/116390",
}


def main_with_sync_client() -> None:
    client = SyncRossumAPIClient(
        base_url="https://elis.rossum.ai/api/v1",
        credentials=UserCredentials(os.environ["ELIS_USERNAME"], os.environ["ELIS_PASSWORD"]),
    )
    ws = client.create_new_workspace(data=WORKSPACE)
    workspace_id = ws.id
    ws = client.retrieve_workspace(workspace_id)
    print("GET result:", ws)
    print("LIST results:")
    for w in client.list_workspaces(ordering=["-id"], name=WORKSPACE["name"]):
        print(w)
    client.delete_workspace(workspace_id)
    print(f"Workspace {workspace_id} deleted.")

Local development

Pull the repository, create a virtual environment, and install the package from the source with test dependencies:

# Create and activate virtual environment
python -m venv .env
source .env/bin/activate

# Install in editable mode with test dependencies
pip install -e .[tests]

We use ruff for linting and formatting. Run all pre-commit hooks with:

pre-commit run --all-files

Or run specific tools:

# Linting and formatting
pre-commit run ruff --all-files
pre-commit run ruff-format --all-files

# Type checking
pre-commit run mypy --all-files

# Run tests
pytest
