Get 401 when calling Check-CaseId-Availability in C#

Hi,
So far I am able to make other calls through C#.
When I try to check for my case id availability, I keep getting 401 but it works in Postman
Can you please review if I make any mistake with the call data?
requestendpoint = "https://api-worldcheck.refinitiv.com/v2/caseIdentifiers?caseId=BENNINGTON_1"
dataToSign = "
(request-target): head /v2/caseIdentifiers?caseId=BENNINGTON_1
host: api-worldcheck.refinitiv.com
date: Tue, 27 Jul 2021 22:04:10 GMT
"
authorization = "Signature keyId="xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",algorithm="hmac-sha256",headers="(request-target) host date",signature="5UB8TMDsCRIO0FIc3Jc7j9QLgLYWehGWc3PiE3keb+w=""
WebReq.Method = "HEAD";
WebReq.Headers.Add("Authorization", authorisation);
WebReq.Headers.Add("Cache-Control", "no-cache");
WebReq.Date = dateValue; // use datetime value GMT time
Thank you,
Cady
