Hi, Try to implement Screen a case like sample SEQ-4a. Post request get Error 400 Bad Request.

I use the postman default group id in the pilot environment.

Please check the source code as below, for the function of “Save a simple case”

// -----------------------

procedure TForm2.btSaveasimplecaseClick(Sender: TObject);

var

response : string;

RequestBody : TstringStream;

tt : TBytes;

dataToSign, strdatetime : string;

thedate : tdatetime;

const

strbody='{ "entityType": "INDIVIDUAL", "groupId":"418f28a7-b9c9-4ae4-8530-819c61b1ca6c","providerTypes": ["WATCHLIST"], "name": "John Doe"}';

strbaseurl='https://rms-world-check-one-api-pilot.thomsonreuters.com/v1/cases';

begin

thedate:=now-(13/24); // get server time , the offset of the time different is 13 hours

strdatetime:= formatdatetime('ddd, dd mmm yyyy hh:mm:ss "GMT"',thedate);

edtdate.Text:=strdatetime; // display purpose – date string

dataToSign:= '(request-target): post /v1/cases'+#10 +'host: rms-world-check-one-api-pilot.thomsonreuters.com' +#10+'date: '+strdatetime+#10+'content-type: application/json'+#10+'content-length: '+

inttostr(length(strbody))+#10+strbody;

msignstring.Lines.Text:=datatosign; // Sign string -- display purpose

tt:=System.Hash.THashSHA2.GetHMACasBytes(dataToSign,APIsecret,SHA256);

edtsignatures.text:=EncodeBase64(tt,length(tt)); // signature string - display purpose

edtauth.Text:='Signature keyId="a4364e62-e58b-4b64-9c71-faead5417557",algorithm="hmac-sha256",headers="(request-target) host date content-type content-length",signature="'+edtsignatures.text+'"'; // authorization string

edit1.Text:=inttostr(length(strbody)); // content -length

RequestBody := TStringStream.Create(strbody, TEncoding.UTF8);

RequestBody.Position := 0;

try

IdHTTP1.Request.CustomHeaders.Clear;

IdHTTP1.Request.Method:=Id_HTTPMethodPost;

IdHTTP1.Request.ContentType := 'application/json';

IdHTTP1.Request.CustomHeaders.AddValue('cache-control', 'no-cache');

IdHTTP1.Request.CustomHeaders.AddValue('authorization',edtauth.Text);

IdHTTP1.Request.CustomHeaders.AddValue('date', strdatetime);

IdHTTP1.Request.CustomHeaders.AddValue('content-type', 'application/json');

IdHTTP1.Request.CustomHeaders.AddValue('content-length', inttostr(length(strbody)));

try

IdHTTP1.Post(strbaseurl, RequestBody);

except

on e:EIdHTTPProtocolException do

begin

showmessage(e.ErrorMessage+' .. '+ e.Message );

end;

on e:exception do

showmessage(e.Message);

end;

memo1.Lines.text:=IdHTTP1.ResponseText;

finally

RequestBody.Free;

Hi, i have found the problem and got this issue resolved. Basically it is the the HTTP component bug does not stream string parameters in order. Also there is another reasons cause the body string not compatible with the REST server. Thanks a lot for the help. John

Hi @information

We do not support IDE environments. However If your GET requests succeed, then the body of your POST request is not formed properly. Perhaps try not encoding the string, first.
