API Query iteration

Thanks Xiaoxin.

I went in a slightly different direction, using List.Accumulate which gave me a list of binary from passing in only one parameter for Query argument. I and was able to get the data in the form I need.

My question now is, how can I pass in a table (3 columns) of values for list in List.Accumulate so it can iterate over all combinations of all parameters?

Ex. 

Table:

So my WebQuery would start with Column A's parameter1value1, then iterate thru ALL values of ColumnB  for parameter2, then all values of ColumnC for parameter3.  Then move to parameter1value2 and repeat process until end of ColumnA.

let
   GetWebData = (statisticType as text) =>
       let
           Source = 
            Web.Contents("https://someapiurl?TIME=parameter1&POLYGON=parameter2&STATISTICS=parameter3", 
                [
                    Query=
                        [
                            STATISTICS=statisticType
                        ]
               
               ]
            )
       in
           Source            
in
   GetWebData


let
   YourList = {parameter3value1, parameter3value2, parameter3value3},
   Result = List.Accumulate(YourList, {}, (state, current) => state & {WebQuery(Text.From(current))}),
in
	Result
