Hi, thanks for replying
Here is what we have:

Which translates to: (the code Postman generates)
var client = new RestClient(“https://api.twitter.com/1.1/tweets/search/fullarchive/ProdFullArchive.json?fromDate=200612220000&query=from%3Ajoelsartore&maxResults=500”);
var request = new RestRequest(Method.GET);
request.AddHeader(“postman-token”, “3d99f70d-b01a-97a6-aa65-8a9f6965346c”);
request.AddHeader(“cache-control”, “no-cache”);
request.AddHeader(“authorization”, “OAuth oauth_consumer_key=“RCA0644lFiOfvX1m4TcvBXzdR”,oauth_token=“958676983-tKavguohyw3VpjLYSpAFWo5hZXPYa34H3Sa1tJdo”,oauth_signature_method=“HMAC-SHA1”,oauth_timestamp=“1541571323”,oauth_nonce=“D1Q46Q”,oauth_version=“1.0”,oauth_signature=“PJxnfsDLTs7bJMLpmN2bV79Ix1c%3D””);
IRestResponse response = client.Execute(request);
or, taking the curl code in Postman:
curl -X GET
‘https://api.twitter.com/1.1/tweets/search/fullarchive/ProdFullArchive.json?fromDate=200612220000&query=from%3Ajoelsartore&maxResults=500’
-H ‘authorization: OAuth oauth_consumer_key=“RCA0644lFiOfvX1m4TcvBXzdR”,oauth_token=“958676983-tKavguohyw3VpjLYSpAFWo5hZXPYa34H3Sa1tJdo”,oauth_signature_method=“HMAC-SHA1”,oauth_timestamp=“1541571323”,oauth_nonce=“D1Q46Q”,oauth_version=“1.0”,oauth_signature=“PJxnfsDLTs7bJMLpmN2bV79Ix1c%3D”’
-H ‘cache-control: no-cache’
-H ‘postman-token: ff64569d-d207-0750-e165-215f0e23e91c’
And in our Authorization Header section:
OAuth oauth_consumer_key=“RCA0644lFiOfvX1m4TcvBXzdR”,oauth_token=“958676983-tKavguohyw3VpjLYSpAFWo5hZXPYa34H3Sa1tJdo”,oauth_signature_method=“HMAC-SHA1”,oauth_timestamp=“1541571323”,oauth_nonce=“D1Q46Q”,oauth_version=“1.0”,oauth_signature=“PJxnfsDLTs7bJMLpmN2bV79Ix1c%3D”
