Cannot refresh query using API

[goWithK]

I have a query but one of parameters is type "query based dropdown list". I do not know the format of json for this parameter.
Please help me!!!

Here is the example I've followed: https://github.com/getredash/redash-toolbelt/blob/master/redash_toolbelt/examples/refresh_query.py

See the below script:

from redash_toolbelt.examples.refresh_query import get_fresh_query_result

HOST = "<your Redash url>"
KEY = "<your api key>"
ID = "<your query id>"

# My test query uses a query-based dropdown parameter named `foo`
# The underlying query returns integers 1 - 5. These are acceptable parameter values.

# The following call succeeds
result = get_fresh_query_result(
    redash_url=HOST,
    query_id=ID,
    api_key=KEY,
    params={"foo": 1},
)

# But this fails...
result = get_fresh_query_result(
    redash_url=HOST,
    query_id=ID,
    api_key=KEY,
    params={"foo": 6},
)

# Because 6 is not an allowed value for `foo`
