Getting an invalid signature... I can't see anything from the NetSuite side.
Our SF developer sent me this.
Obviously removed some stuff for security reasons.
HttpRequest req = new HttpRequest();
req.setEndpoint('myRestletUrl');
req.setMethod('GET');
req = OAuth.signRequest(req, '1234','2345','5678','realm with _SB1', 'Mozilla/5.0');
Http h = new Http();
HTTPResponse resp = h.send(req);
System.debug('HTTPResponse ' + resp);
@scottvonduhn + this class you sent me in that github repo.
