    thediez  Can you check that credentials are set to Anonymous for the data source (since using Bearer Token)?

Hi thediez 

Try making this change:

body = Text.ToBinary(""),

This seemed to work for me for another API POST request.

 

Does this work for you?

Hi OwenAuger ,

 

Thanks for the suggestion.

 

I have updated as follows:

 

let
    body = Text.ToBinary(""),
    Source = Json.Document(Web.Contents("https://www.vptol.co.uk/dlatest/QuestionnaireDataWithProfile?org=whoglmat&typ=WHOData", [Headers=[#"Authorization"="Bearer "&GetAccessTokenForAcasiResponses()], Content=body]))
in
    Source

 

But now getting this message.

I suspect that adding "Content" in the brackets after "Header" is causing this error.

 

Kind regards,

Khurshed
