I tried using this url for consuming API, but getting error 'The Given Header was not Found'.

   

Don't know what's wrong, when i try in Postman it works.

Below Code for reference,

RSetup.Get();


Initialize;
JsonTextWriter.WriteStartObject;
JsonTextWriter.WritePropertyName('action');
JsonTextWriter.WriteValue('INITAUTH');
JsonTextWriter.WritePropertyName('UserName');
JsonTextWriter.WriteValue(RSetup."API User Name");
JsonTextWriter.WritePropertyName('GstinNo');
JsonTextWriter.WriteValue(RSetup."API GSTIN");
JsonTextWriter.WriteEndObject;
JSON := StringBuilder.ToString;

HttpWebRequestMgt.Initialize(RSetup."API Auth URL");

HttpWebRequestMgt.DisableUI();

HttpWebRequestMgt.SetMethod('POST');

HttpWebRequestMgt.SetContentType('application/json')

HttpWebRequestMgt.SetReturnType('application/json')


HttpWebRequestMgt.AddHeader('client_id',RSetup."API Client ID");

HttpWebRequestMgt.AddHeader('client_secret',RSetup."API Client Secret");

HttpWebRequestMgt.AddHeader('IP',RSetup."API IP");

HttpWebRequestMgt.AddHeader('AuthDateTime',FORMAT(CURRENTDATETIME));

HttpWebRequestMgt.AddBodyAsText(JSON);

TempBlob.INIT;

TempBlob.Blob.CREATEINSTREAM(Instr);

IF NOT HttpWebRequestMgt.GetResponse(Instr,HTTPStatusCode,ResponseHeader)THEN

HttpWebRequestMgt.ProcessFaultResponse(Response);

IF HTTPStatusCode.ToString <> HTTPStatusCode.OK.ToString THEN

 ERROR(TempBlob.ReadAsText('',TEXTENCODING::UTF8));

Response := TempBlob.ReadAsText('',TEXTENCODING::UTF8);

MESSAGE(Response);

Response what i receive,

{"MessageId":-1,"Message":"The given header was not found.","ErrorCode":null,"Data":null,"ResponseJson":null,"Status":null}

I am using Codeunit 1297 'Http Web Request Mgt.".

    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

    www.dynamicsuser.net/.../14

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

    Thanks.

    Hey Marco,

    Thank for your reply, solved the issue, there was a hidden character which was giving issue in the baseurl.

    I copied URL hence issue.
