Filter API Query with a List

[RappJ]

Good day all,
I am trying to filter an API query from a List in BI. 
let
Source = Json.Document(Web.Contents("https://qwerty.co/api/v9/qwerty?api_key=1234567890&API_Request_Parameter=list")),
#"Converted to Table" = Table.FromRecords({Source}),

I would like to add a filter after the API key that will itterate through each item in the list.

Regards,
Jason

Thank you, I had to make some additional changes as the filter list was compiled form an outside source.
