I am trying to generate REST API token dynamically from Power BI Desktop, using power Query. I am not sure what is causing this error. Any help is appreciated.
An error occurred in the ‘’ query. DataSource.Error: Web.Contents failed to get contents from 'https://login.mypurecloud.com.au/oauth/token' (400): Bad Request
Details:
DataSourceKind=Web
DataSourcePath=https://login.mypurecloud.com.au/oauth/token
Url=https://login.mypurecloud.com.au/oauth/token
Solved! Go to Solution.
After making few minor changes the code is generating token in Power BI . here is the modified code
let
GenerateToken = () =>
let
url = "https://login.mypurecloud.com.au/oauth/token",
body = "grant_type=client_credentials&client_id=<client-id>&client_secret=<Clinet_secret>",
headers = [#"Content-Type" = "application/x-www-form-urlencoded"],
response = Web.Contents(url, [Headers = headers, Content = Text.ToBinary(body)]),
jsonResponse = Json.Document(response),
accessToken = jsonResponse[access_token]
in
accessToken
in
GenerateToken

Hi,
Thanks for your support. i tried using above code , still gettig the same error. . Please see the attached screenshots. in the second script i just tried displaying the token value instead passing the value to retrieve the data.
Postman is generating the token and retrieving the data for the same credentials
for the same URL and
Hi @Anonymous ,
You can try the following code in general:
let
GenerateToken = () =>
let
url = "https://login.mypurecloud.com.au/oauth/token",
body = "grant_type=client_credentials&client_id=YOUR_CLIENT_ID&client_secret=YOUR_CLIENT_SECRET",
headers = [#"Content-Type" = "application/x-www-form-urlencoded"],
response = Web.Contents(url, [Headers=headers, Content=Text.ToBinary(body)]),
jsonResponse = Json.Document(response),
accessToken = jsonResponse[access_token]
in
accessToken
in
GenerateToken
let
token = GenerateToken(),
url = "https://api.yourservice.com/data",
headers = [#"Authorization" = "Bearer " & token],
response = Web.Contents(url, [Headers=headers]),
data = Json.Document(response)
in
data
Hope it helps!
