Can query parameters be applied to functions?

I have a function that retrieves data from a web API. One of the fields to be passed to the API accepts just two values, "10-Q" and "10-K". I've read the blog posts about parameters and created a parameter list with these two values, but is there a way to use that parameter right in the function definition (i.e. not in a downstream query)? This would work as a form of data validation when the function is invoked.

 

Screenshot below to try and clarify what I mean:

 

 

 

  • Hi otravers

     

    I think that you can put your variable as part of your function in your code below.

     

    let
        Source = (ticker as text, FormTypes as text, order as text) as table =>
    let
        Source = Json.Document(Web.Contents("https://services.last10k.com/v1/company/" & #"ticker" & "/balancesheet?formType=" & #"FormTypes" & "&filingOrder=" & order, [Headers=[#"Ocp-Apim-Subscription-Key" = "redacted"]])),
        #"Converted to Table" = Record.ToTable(Source),
        #"Transposed Table" = Table.Transpose(#"Converted to Table"),
        #"Promoted Headers" = Table.PromoteHeaders(#"Transposed Table")
    in
        #"Promoted Headers"
    in
        Source

    What I have done is to change it from your parameters in your Source line which might work?

     

        Source = Json.Document(Web.Contents("https://services.last10k.com/v1/company/" & #"ticker" & "/balancesheet?formType=" & #"FormTypes" & "&filingOrder=" & order, [Headers=[#"Ocp-Apim-Subscription-Key" = "redacted"]])),
