Pull data from API using POST method in Power BI

[TuanPham1999]

Hi all, I'm a fresher in Power BI Desktop. my mission is extract data from given credentials include: ClientID, Password and Url. The credentials must be Base64 encoded for use in the POST /oauth2/token request. I have used that credentials in Postman and I got its header such as: Authorization: Basic xxxxxxxxxxxxxxxxxxxxxx. what should i start with all of them to get data from API. Can anyone help me to solve this probleml. thank you so much for any solution and suggestion. Cheer!!!

I found it not so easy to get data via POST so I am pasting here what I did in case this helps someone else in the future.

I created the following blank query:

= let
   body = "The POST method body here",
   Data= Web.Contents("https://yourusrlhere",[Content=Text.ToBinary(body),Headers=[#"Content- 
   Type"="application/json"]]),
   DataRecord = Json.Document(Data),
   Source=DataRecord 
in
   Source

I wanted to post a more complete/cleaner version of the above solution that contains multiple headers and shows how to convert the body to binary data for POST operations: 

let
    url = "https://api.somevendor.com/api/",
    headers = [#"Content-Type" = "application/x-www-form-urlencoded", #"Accept" = "application/json"],
    postData = "Any sort of text data you want to post to the API",
    response = Web.Contents(
        url,
        [
            Headers = headers,
            Content = Text.ToBinary(postData)
        ]
    ),
    jsonResponse = Json.Document(response)
in
    jsonResponse

What  body = "The POST method body here", is for?

Thanks
