Hi Everyone,
I'm trying to connect to my external application through RESTFUL WEB services from powerbi desktop. I'm new to powerbi application, could you please help me out.
let
url = "https://XXX/api/",
body = "{""token"": ""XXXXXX"",""content"":""record"",""format"":""json"",""type"":""flat"",""returnformat"":""json""
}",
Source = Json.Document(Web.Contents(url,[
Headers = [#"Content-Type"="application/json"],
Content = Text.ToBinary(body)
]
))
in
Source
the external application supports only POST method - I tried with the Google Chrome postman with same parameters it worked. I don't know how to do it this in powerbi

Chris shows how to send a POST here.
Thanks,
I checked with https://blog.crossjoin.co.uk/2014/04/19/web-services-and-post-requests-in-power-query/ post, I'm getting same error.
Now, I'm getting the below error
DataSource.Error: Web.Contents with the Content option is only supported when connecting anonymously.
Details:
DataSourceKind=Web
DataSourcePath=XXXX/api
let
url = "XXXXXXXXXXXX/api/",
body = "{""token"": ""XXXXXXXXXXXXXXXXXXXXXX"",""content"":""record"",""format"":""json"",""type"":""flat"",""returnformat"":""json""
}",
Source = Json.Document(Web.Contents(url,
[
Headers = [#"Content-Type"="application/json"],
Content=Text.ToBinary(body)
]
)
)
in

Sorry, I am useless. I just recalled Chris had posted about POST. I would be doing to begging for help on google: https://community.powerbi.com/t5/Service/Anonymous-access/td-p/19136 🙂
