API Queries

Good afternoon dear,

It is the first time that I work with API's in PBI and I do not handle correctly all the concepts/errors that they can carry out.


I have to connect to an API and extract the data of the workers.

API documentation: https://demo.buk.cl/apidocs#/

 

Employees: 

 

 

= (Page as number) =>
let
    Source = Json.Document(Web.Contents("INSERT URL?page="&Number.ToText(Page), [Headers=[token="xxxxxxxxxxxxxxx"]])),
    data = Source[data],
    #"Converted to Table" = Table.FromList(data, Splitter.SplitByNothing(), null, null, ExtraValues.Error),
    #"Expanded Column1" = Table.ExpandRecordColumn(#"Converted to Table", "Column1", {"full_name", "rut"}, {"full_name", "rut"})
in
    #"Expanded Column1"

 

 

Query:

 

 

= List.Generate(()=> 
[Result = try employees(1) otherwise null, Page = 1], 
each [Result] <> null, 
each [Result = try employees([Page]+1) otherwise null, Page = [Page]+1],
each [Result])

 

 

Tutorial I followed: https://www.youtube.com/watch?v=05yhwnuCjRw

 

There is no problem in the data I get, but the problem starts when I need to update it automatically in PBI Service, where I get the following error:

Ivancito111_0-1649347971033.png

English translation:

This dataset includes a dynamic data source. Since these sources are not updated in the Power BI service, this dataset will not be updated. Learn more at https://aka.ms/dynamic-data-sources.
Query1 data source

 

I would like if someone could guide me what modification should I make to update automatically or if it is already impossible to update in this way.

 

Thank you very much for your time, have a nice day.

Hi @Ivancito111 ,

 

Please try use the Query option in Web.contents function:

 

(Page as number) =>
let
    Source = Json.Document(Web.Contents("https://xxxx/api/v1/chile/employees",[Query=[page=Number.ToText(Page)], Headers=[auth_token="xxxxxx"]])),
    data = Source[data],
    #"Converted to Table" = Table.FromList(data, Splitter.SplitByNothing(), null, null, ExtraValues.Error),
    #"Expanded Column1" = Table.ExpandRecordColumn(#"Converted to Table", "Column1", {"full_name", "rut"}, {"full_name", "rut"})
in
    #"Expanded Column1"
let
    Query1 = List.Generate(()=> 
[Result = try employees(1) otherwise null, Page = 1], 
each [Result] <> null, 
each [Result = try employees([Page]+1) otherwise null, Page = [Page]+1],
each [Result]),
    Query2 = Query1{0}
in
    Query2

 

Then publish report and select "Skip test connection" for this data source.
