How to Pass GUID in header for post request to third party api

(0) ShareShare
ReportReport
Posted on by 142

Hello to all, 
I want to send post request to third party api to retrieve token, where in header pass 'guid' as authorization. Like on picture in postman:

From postman works well, but when I want from business central I got 401 error.

This is my procedure in codeunit:
pastedimage1671613978336v3.png

and on Employee Card I add action where call function from codeunit:
 pastedimage1671614199365v4.png

and got
pastedimage1671614329071v5.png
But if remove 'content-type' I got 401 error.

Do you know where I am wrong? I try to pass  'Bearer' ,'Token', and 'Basic' without coding to base64 but same results

I have the same question (0)

    Yes you are right.

    It seems space in and other non hex letters are problem too.

    Now I try another api but get this error:

    An error occurred while sending the request. The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.

    do you know what that could be?

    hi

    I think the guid problem is over

    this error, on the other hand, I don't know exactly what it is due to

    but I enclose this

    stackoverflow.com/.../could-not-establish-trust-relationship-for-ssl-tls-secure-channel-soap

    check my answer if it helped you, thanks

    hi DAnny3211  thank you very much.

    I wanted to ask you do you know how to pass parameters into httpbody?

    I have that one GUID parameter for authorization into header, but have two parameters (Username, Password) into body. But don't know how to pass that values in AL.

    Hi,

    Try to get an idea from below code.

      var
            bulkArrayPayload: JsonArray;
            JsonText: text;
            Location: record Location;
            RespMessage: text;
            http_Client: HttpClient;
            httpReqMsg: HttpRequestMessage;
            httpResMsg: HttpResponseMessage;
            http_Content: HttpContent;
            http_Header: HttpHeaders;
            serviceResponse: text;
            URL: Text;
        begin
            RespStatus := '';
            Clear(bulkArrayPayload);
            clear(httpResMsg);
            Clear(serviceResponse);
            bulkArrayPayload.Add(JSOObject);
            bulkArrayPayload.WriteTo(JsonText);
            if CopyStr(JsonText, 1, 1) = '[' then begin
                JsonText := CopyStr(JsonText, 2, StrLen(JsonText));
                JsonText := CopyStr(JsonText, 1, StrLen(JsonText) - 1);
            end;
            http_Client.Clear();
            http_Content.Clear();
            http_Content.WriteFrom(JsonText);
            http_Content.GetHeaders(http_Header);
            http_Header.Clear();
            http_Client.DefaultRequestHeaders.Add('Authorization', 'Bearer ' + APIKey + '');
            http_Header.Add('Content-Type', 'application/json');
            if http_client.Post(APIURL, http_Content, httpResMsg) then begin
                httpResMsg.Content.ReadAs(serviceResponse);
                RespStatus := 'Pass';
                if (httpResMsg.HttpStatusCode <> 200) or (StrPos(serviceResponse, 'error') > 0) then
                    RespStatus := 'Failed';
            end;
            exit(serviceResponse);
        end;

    From AL you will typically need to add the token as a header just like Nitin showed you in his code sample.
