Splunk SOAR SDK - the official tool for Splunk SOAR app development

Documentation

Detailed documentation can be found here

Installation

The Splunk SOAR SDK is available as a package on PyPI.

The recommended installation method is via uv.

Installing the SDK as a tool

This package defines the soarapps command line interface. To use it, install as a uv tool:

uv tool install splunk-soar-sdk
soarapps --help

Quick Start

Create a new, empty app: Run soarapps init.

Migrate an existing app to the SDK: Run soarapps convert myapp, where myapp is your app written using BaseConnector. This will convert asset configuration, action declarations, and inputs and outputs. You'll still need to re-implement your action code, as well as any custom views and webhooks.

Getting Help

If you need help, please file a GitHub issue at https://github.com/phantomcyber/splunk-soar-sdk/issues.

Installing the SDK as an app dependency

When developing a new Splunk SOAR app using the SDK, you should use uv as your project management tool:

uv add splunk-soar-sdk

Running the above command will add splunk-soar-sdk as a dependency of your Splunk SOAR app, in your pyproject.toml file.

Usage

In order to start using SDK and build your first Splunk SOAR App, follow the Getting Started guide.

A Splunk SOAR app developed with the SDK will look something like this:

Project structure:

string_reverser/
├─ src/
│  ├─ __init__.py
│  ├─ app.py
├─ tests/
│  ├─ __init__.py
│  ├─ test_app.py
├─ .pre-commit-config.yaml
├─ logo.svg
├─ logo_dark.svg
├─ pyproject.toml

With app.py containing:

from soar_sdk.abstract import SOARClient
from soar_sdk.app import App
from soar_sdk.asset import AssetField, BaseAsset
from soar_sdk.params import Params
from soar_sdk.action_results import ActionOutput


class Asset(BaseAsset):
    base_url: str
    api_key: str = AssetField(sensitive=True, description="API key for authentication")


app = App(name="test_app", asset_cls=Asset, appid="1e1618e7-2f70-4fc0-916a-f96facc2d2e4", app_type="sandbox", logo="logo.svg", logo_dark="logo_dark.svg", product_vendor="Splunk", product_name="Example App", publisher="Splunk")


@app.test_connectivity()
def test_connectivity(client: SOARClient, asset: Asset) -> None:
    client.debug(f"testing connectivity against {asset.base_url}")


class ReverseStringParams(Params):
    input_string: str


class ReverseStringOutput(ActionOutput):
    reversed_string: str


@app.action(action_type="test", verbose="Reverses a string.")
def reverse_string(
    param: ReverseStringParams, client: SOARClient
) -> ReverseStringOutput:
    reversed_string = param.input_string[::-1]
    return ReverseStringOutput(reversed_string=reversed_string)


if __name__ == "__main__":
    app.cli()

Requirements

• uv
• Python >=3.9
  • Python may be installed locally with uv
• Splunk SOAR >=6.4.0
