API header in Web.Contents is not respected.

Need to make API GET request with following headers especially 'q' search term which i but this doesn't seem to be respecting it. Can anyone help me out on this, if the following code has a mistake in it? The API header here is coming from an excel file and API is executing on it. 

The search results with 'URL' in the JSON response which should be different for search terms (i.e., q) but here it doesn't seem to be respecting it. 

let
    Query2 = let
    Source = Excel.Workbook(File.Contents("C:\Users\nitin.chawda\Documents\InputSearchIRDText.xlsx"), null, true),
        SourceData_Table = Source{[Item="Sheet1",Kind="Sheet"]}[0][Data],
       #"Filtererd_Rows" = Table.TransformColumns(SourceData_Table)
  in Source,
    Sheet1_Sheet = Query2{[Item="Sheet1",Kind="Sheet"]}[Data],
    #"Promoted Headers" = Table.PromoteHeaders(Sheet1_Sheet, [PromoteAllScalars=true]),
    #"Changed Type" = Table.TransformColumnTypes(#"Promoted Headers",{{"Search_Term", type text}, {"Search_Scope", type text}, {"Type_of_Facet", type text}, {"Page_Number", type text}, {"Item_id", type text}}),
//Start custom function to read records in table. Here is where the error is.

apiLoadSheetFunction = (_ as record) =>

let
    url = "https://www.ird.govt.nz//sxa/search/results/",
    headers = [
        #"Content-Type" = "application/json",
        #"q" =  " & Text.From(_[Search_Term]) & ",
        #"s" = " & Text.From(_[Search_Scope]) & ",
        #"type" = " & Text.From(_[Type_of_Facet]) &",
        #"itemid" = " & Text.From(_[Item_id]) &",
        #"e" = "& Text.From(_[Page_Number]) &"],
	webdata = Web.Contents(url, [Headers=headers, ManualStatusHandling={400..499}]),
    response = Json.Document(webdata),
    Source = response

in 
    response,
    
	AStepName = Table.AddColumn(#"Changed Type", "APICall", each apiLoadSheetFunction(_)),
    #"Expanded APICall" = Table.ExpandRecordColumn(AStepName, "APICall", {"Results"}, {"APICall.Results"}),
    #"Expanded APICall.Results" = Table.ExpandListColumn(#"Expanded APICall", "APICall.Results"),
    #"Expanded APICall.Results1" = Table.ExpandRecordColumn(#"Expanded APICall.Results", "APICall.Results", {"Url"}, {"APICall.Results.Url"})
in
    #"Expanded APICall.Results1"

 Something wrong with above code?

Hi @Anonymous ,

Firstly, do you get any error message with the M query?

In addition, do you only have the issue with 'q' search term ? What about 's' search_scope?

What's more, you could have a reference of the link below.
