POST Authentication to a REST API

[dcoronno]

Hi,

I am having issues doing a POST method in M to grab an authentication token.
Specifically I am trying to grab data out of the REST API to Power Query for Excel..

They have given a piece of curl code, but I am having trouble dissecting it into M.

curl -X POST --user {user}:'{password}' https://auth.anaplan.com/token/authenticate

Any help would be appreciated

Hi @dcoronno ,

You could try this

Get Access token in Power BI Desktop:


 

() =>

 

let

    body = "client_id=" & #"App ID"

    & "&scope=https://analysis.windows.net/powerbi/api/.default&client_secret=" & #"App Secret"

    & "&grant_type=client_credentials",

    Data= Json.Document(Web.Contents("https://login.microsoftonline.com/"& TenantID & "/oauth2/v2.0/token/",

    [Headers=[#"Content-Type"="application/x-www-form-urlencoded"], Content=Text.ToBinary(body)])),

    access_token = Data[access_token]

in

    access_token

This is the official document you can refer to.

Hi,

I was fighting with retrieving authentication tokens for some time. Here's what worked in my situation. The following is a function to retrieve an Auth Token which i then call in several different data queries. You may need to change the content type. Hope you can make it work for you! 

let
Source = () =>
let
body = "{
""user"": ""UserHere"",
""pass"": ""PassHere""
}",
Data=Json.Document(Web.Contents("https://LinkHere", [Headers=[#"Content-Type"="application/json"], Content=Text.ToBinary(body)])),
access_token = Data[token]
in
access_token
in
Source

cheers,

Keith

You call Web.Contents with a Content payload to transform a GET call into a POST call.
