Power Query : http POST request with form data

0 votes

So, there's REST API I have, which accepts only POST requests with form data.

I know that JSON requests are like this in Power Query :

let
    url = "https://example.com",
    body = "{ ""first_param"": ""AAAAA"",  ""second_param"": ""BBBBBB""}",    

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

So my question is that Is it possible to send form data?? and How?

Thanks.

Try using Uri.BuildQueryString and Json.Document.

let
    url = "https://example.com",
    body  = "{ ""first_param"": ""AAAAA"",  ""second_param"": ""BBBBBB""}",
    Parsed_JSON = Json.Document(body),
    BuildQueryString = Uri.BuildQueryString(Parsed_JSON),
    Source = Json.Document(Web.Contents(url,[Headers = [#"Content-Type"="application/json"], Content = Text.ToBinary(body) ] ))
in
    Source

Hope this helps!
