Pulling specific parameters other than action=list from an API

[user180618]

I am using Qualys's API documentation to pull their endpoints into Power Query. Doing the below works fine:

let
Url = "https://qualysapi.qualys.eu/api/2.0/fo/knowledge_base/vuln/",
AuthString = "Basic ###############################",
Source = Xml.Tables(
Web.Contents (
Url,
[
Headers = [ #"Authorization" = AuthString,
#"X-Requested-With" = "Power BI"],
Query = [action = "list"],
Content = Text.ToBinary("")
]

)
)

However, I'm not sure how to modify the 'Query' line to pull multiple parameters from the API, for example so that I can use both action=list and also something like echo_request.

Appreciate any suggestions.

Query = [action = "list", echo_request = "1"],
