Many of the Swimlane RESTful API endpoints require JSON payloads. However, the POST /task/upload-script endpoint requires multipart/form-data.

To learn how to interact with this endpoint, or any other, it’s best to inspect the Swimlane UI’s manner of interacting with the endpoint:

Here is the successful POST:

Here is the POST body payload that needs to be replicated in client Python code:

Here is a Python 3.7 code sample, which relies on the Swimlane Driver for authentication and for ease of retrieving the pertinent application’s ID value, illustrating how to make this POST:

:::BlockQuote
from swimlane import Swimlane
host = 'https\://SWIMLANE-HOST'
swimlane = Swimlane(host, 'USER', 'PASSWORD', verify\_ssl=False)
app = swimlane.apps.get(name='APPLICATION-NAME')
	
resp = swimlane.request(
    'post',
    '/task/upload-script',
	data=\[
		("taskName", "do\_some\_cool\_secops.py"),
		("scriptType", "Python"),
		("appId", app.id)
	],
	files=\{
		"file": open(r'C:\Swimlane\shared\do\_some\_cool\_secops', 'rb'),
		"contentType": "text/plain"
	}
)

print str(resp.status\_code)
print resp.text
:::


The two supported file types are .py (Python scripts) and .ps1 (Powershell scripts).
