How to create an "analysis specification" by JSONAPI

1

Hello,
Can someone show me an example of how to create “analysis specificaton” by JSONAPI?

by the code in below, it could create an analysis specification with blank value.
i didn’t know how to set result range while creating analysis specification.

data = {
# “parent_id”: “bika_analysisspecs”,
“title”: spec_name,
“description”: DESC,
“portal_type”: “AnalysisSpec”,
“SampleType”: sampletype_UID,
“parent_path”: “/senaite/bika_setup/bika_analysisspecs”,
}

url = url_base + “/create”
requests.post(url, data=data, auth=auth)

thanks a lot in advance.
