Hello Experts,
We are building a Power BI connector to extract data from one of our systems that expose data via Rest API. Hoping that you can guide me in right direction with following issue
API structure as follows:
baseURI: https://api.myapp.com/api/rest/
API end point for document list: https://api.myapp.com/api/rest/documents/ => (returns a list of docIDs)
API end point for document users: https://api.myapp.com/api/rest/documents/docID/users
After getting response from List API, I am try to add a new column by invoking a custom function that accepts docID as parameter and then invoke document users API.
I get the following error: Expression.Error: Access to the resource is forbidden.
Tried changing the Privacy levels at Data source settings but no luck!
It works fine when I try to hard code any docID instead of passing as a parameter. Kindly find my code below and request you to help. Thanks!
Query1:
let
DefaultRequestHeaders = [
#"Accept" = "application/json", // column name and values only
#"Authorization" = "****",
#"client_id" = "****",
#"client_secret" = "****",
],
source = Web.Contents("https://api.myapp.com/api/rest/", [ RelativePath = "documents", Headers = DefaultRequestHeaders ]),
json = Json.Document(source),
docList = json[docList],
#"Converted to Table" = Table.FromList(docList, Splitter.SplitByNothing(), null, null, ExtraValues.Error),
#"Expanded Column1" = Table.ExpandRecordColumn(#"Converted to Table", "Column1", {"id"}, {"id"}),
#"Invoked Custom Function" = Table.AddColumn(#"Expanded Column1", "Query2", each Query2([id]))
in
#"Invoked Custom Function"
Query2:
let
GetUsers = (docId as text) as table =>
let
DefaultRequestHeaders = [
#"Accept" = "application/json", // column name and values only
#"Authorization" = "****",
#"client_id" = "****",
#"client_secret" = "****",
],
source = Web.Contents("https://api.myapp.com/api/rest/", [ RelativePath = "documents/"&docId&"/users", Headers = DefaultRequestHeaders ]),
json = Json.Document(source),
#"Converted to Table" = Record.ToTable(json),
#"Pivoted Column" = Table.Pivot(#"Converted to Table", List.Distinct(#"Converted to Table"[Name]), "Name", "Value")
in
#"Pivoted Column"
in
GetUsers
