API query return a range of selection

Hi Experts,

 

I have an API key like below that is working, no problem.  However, how do I modify my query to return more than one objectno?  For example objectno range that is 001 to 020?

 

Json.Document(Web.Contents("https://csv.business.tomtom.com/extern?account=AAAc&username=XXX&password=PPP&apikey=818c28e9-09ec-4...objectno=001&outputformat=json"))

 

Thanks,

Raymond

Hi @clubspec ,

You can try to create a custom function like this and use it in the number table column:

(Page as text) =>
let
    Source = Json.Document(Web.Contents("https://csv.business.tomtom.com/extern?account=AAAc&username=XXX&password=PPP&apikey=818c28e9-09ec-4...objectno="&Page&"&outputformat=json"))
in
    Source
let
    Source = List.Numbers(1,20,1),
    #"Converted to Table" = Table.FromList(Source, Splitter.SplitByNothing(), null, null, ExtraValues.Error),
    #"Changed Type" = Table.TransformColumnTypes(#"Converted to Table",{{"Column1", type text}}),
    Custom1 = Table.TransformColumns(#"Changed Type", {"Column1", each Text.PadStart(_, 3, "0"), type text}),
    #"Invoked Custom Function" = Table.AddColumn(Custom1, "function2", each function2([Column1]))
in
    #"Invoked Custom Function"

since it needs API key, currently it returns errorsince it needs API key, currently it returns error

Here's one way to do it in the query editor.  To see how it works, just create a blank query, open the Advanced Editor and replace the text there with the M code below.

let
    Source = List.Numbers(1,19,1),
    #"Converted to Table" = Table.FromList(Source, Splitter.SplitByNothing(), null, null, ExtraValues.Error),
    #"Changed Type" = Table.TransformColumnTypes(#"Converted to Table",{{"Column1", type text}}),
    Custom1 = Table.TransformColumns(#"Changed Type", {"Column1", each Text.PadStart(_, 3, "0"), type text}),
    #"Added Custom" = Table.AddColumn(Custom1, "Custom", each Json.Document(Web.Contents("https://csv.business.tomtom.com/extern?account=AAAc&username=XXX&password=PPP&apikey=818c28e9-09ec-4...objectno=" & [Column1]&"outputformat=json")))
in
    #"Added Custom"

Thanks Pat but it returns error:

"DataFormat.Error: We found extra characters at the end of JSON input.
Details:
Value=,
Position=4"

 

If I query one objectno at a time, it will return a list, from there I convert the list to a table.

Thanks in advance

Try taking out the Json.Document wrapper and just do Web.Contents to see what you get, and confirm/see the structure of the JSON.  Share screen shots of what you get back (if you can), if the issue is not obvious to you.
