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

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
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
