Google Apps Script to LogicMonitor REST API | Archive

I am trying to use the REST API from Google Apps Script but having trouble getting the auth signature to match the expected values. The code executes but I get HTTP 403 back because the auth signature is not as expected. Here's my Google Apps Script code, hoping someone from LM can point me in the right direction. I know my accessKey etc. are okay as my PowerShell code works just fine. Thanks in advance. <span class="pln"> var httpVerb = "GET"; var epoch = (new Date).getTime(); var resourcePath = "/device/groups"; var queryParams = "?filter=fullPath~Business Services&fields=id,name"; // Construct signature var requestVars = httpVerb + epoch + resourcePath; var message = requestVars; var secret = accessKey; var signature = Utilities.computeHmacSha256Signature(message, secret, Utilities.Charset.UTF_8); var signatureHex = ""; for (var i = 0; i < signature.length; i++) { signatureHex += (signature<i>).toString(16); } signatureHex = signatureHex.split("-").join(""); signature = Utilities.base64Encode(signatureHex); Logger.log(signatureHex); Logger.log(signature); // Construct HTTP request headers var auth = "LMv1 " + accessId + ":" + signature + ":" + epoch; var options = { "Authorization" : auth, "method" : httpVerb, "contentType" : "application/json" }; var url = "https://" + accessCompany + ".logicmonitor.com/santaba/rest" + resourcePath + queryParams; var response = UrlFetchApp.fetch(url, options); Logger.log(response.getContentText());</i></span>
