M Query to use POST method on a Web API

Hi,

Thanks for the response.

I have the Sage One documentation and have updated my query to:

let

body=
"{
  ""FromDate"": ""2017-01-01"",
  ""ToDate"": ""2018-01-01""
}",

url = "https://accounting.sageone.co.za/api/1.1.2/AccountBalance/Get?ApiKey={GUID-GUID-GUID}&CompanyId=12345",

Source = Json.Document(Web.Contents(url,[ Headers = [#"Content-Type"="application/json"], Content = Text.ToBinary(body) ] ))

in Source

but Im getting this error:

DataSource.Error: Web.Contents with the Content option is only supported when connecting anonymously.
Details:
    DataSourceKind=Web
    DataSourcePath=https://accounting.sageone.co.za/api/1.1.2/AccountBalance/Get

Can you advise?

Thanks

Digiroo
