Blank JSON Response

Posted on by Charan_12 115

I am sending a Json Post request to a API.

The HTTP Response Message is successful, however the content is blank

The same request in Postman returns content. 

       HttpContentVAR.WriteFrom(JsonText);
        HttpClientVAR.Send(HttpRequestVAR, HttpResponseMessageVAR);

        if not HttpResponseMessageVAR.IsSuccessStatusCode then
            error('The web service returned an error message:\\' +
                  'Status code: %1\' +
                  'Description: %2',
                  HttpResponseMessageVAR.HttpStatusCode,
                  HttpResponseMessageVAR.ReasonPhrase);

        HttpResponseMessageVAR.Content.ReadAs(JsonResponseText);

    Also, not seeing the full code: Check you're actually adding the request content to the HttpRequest object?

    Could be you're sending a blank request?

    Hi,

    You might need to add some headers to your request.

    Have a look at the header section in postman and double check you're applying the same in AL.

    Hello  - We currently do not have dedicated Dev support via the Dynamics 365 Business Central forums, but I wanted to provide you some additional resources to assist.  If you need assistance with debugging or coding I would recommend discussing this on one of our communities.

    www.yammer.com/dynamicsnavdev

    dynamicsuser.net/.../developers

    I will open this up to the community in case they have something to add.
