Call Power BI API in Power Query - powershell

Question

I'm trying to retrieve data from Power BI API services and the same is being accomplished via PowerShell code. But unfortunately due to some circumstances I am not able to deploy it in production. Hence now I am trying to get the same thing done in Power BI desktop itself so that I can call power BI rest API from Power Query only. There are tons of blogpost about calling an API in power query but they all require Power BI App registered Client ID. Which I don't have. I'm successfully able to call with my user name password in PowerShell and even I'm getting response from API.
Please find below PowerShell code and let me know if we can replicate the same in Power Query.
# User credential
$User = 'shahab***#*****.com'
$Pword = ConvertTo-SecureString –String '***password***' –AsPlainText -Force
$Credential = New-Object –TypeName System.Management.Automation.PSCredential –ArgumentList $User,$Pword
# Connect to service
Login-PowerBIServiceAccount -Credential $Credential
#Get Bearer token
$headers = Get-PowerBIAccessToken
$uri = 'https://api.powerbi.com/v1.0/myorg/datasets/f52f2abc-6445-41ee-ce02-3908c6e18dd4/refreshes'
$refreshes = Invoke-RestMethod -Uri $uri -Headers $headers -Method GET
$xs= $refreshes
Thanks.

With the wrapper, you want something like this.
WebRequest_Simple(
"https://api.powerbi.com",
"v1.0/myorg/datasets/f52f2abc-6445-41ee-ce02-3908c6e18dd4/refreshes",
[
Headers = [ Authorization = "Bearer OAuthTokenHere" ]
]
)
If the url had a query string (the part after ?), then you'd use options[Query]
Web Response
Full Query
Source: WebRequest_Simple.pq
let
/*
Wrapper for Web.Contents returns response metadata
for options, see: <https://learn.microsoft.com/en-us/powerquery-m/web-contents#__toc360793395>
*/
WebRequest_Simple
= (
base_url as text,
optional relative_path as nullable text,
optional options as nullable record
)
as record =>
let
headers = options[Headers]?, //or: ?? [ Accept = "application/json" ],
merged_options = [
Query = options[Query]?,
RelativePath = relative_path,
ManualStatusHandling = options[ManualStatusHandling]? ?? { 400, 404 },
Headers = headers
],
bytes = Web.Contents(base_url, merged_options),
response = Binary.Buffer(bytes),
response_metadata = Value.Metadata( bytes ),
status_code = response_metadata[Response.Status]?,
json = Json.Document(response),
Final = [
request_url = metadata[Content.Uri](),
status_code = status_code,
metadata = response_metadata,
IsJson = not (try json)[HasError],
response = response,
json = json
]
in
Final,
tests = {
WebRequest_Simple("https://httpbin.org", "json"), // expect: json
WebRequest_Simple("https://www.google.com"), // expect: html
WebRequest_Simple(
"https://api.powerbi.com",
"v1.0/myorg/datasets/f52f2abc-6445-41ee-ce02-3908c6e18dd4/refreshes",
[
Headers = [ Authorization = "Bearer OAuthTokenHere" ]
]
)
},
FinalResults = Table.FromRecords(tests,
type table[
status_code = text, request_url = text, metadata = record,
response = binary, IsJson = logical, json = any],
MissingField.Error
)
