Unable to authenticate Rest api with servicenow to get devices
Hi All, I am trying to authenticate in servicenow using script but it is not working. It is throwing an error authentication failed status 401. var ACCESS_ID = '123'; var ACCESS_KEY = 'abc'; var ACCOUNT_NAME = 'test'; var resourcePath = '/device/devices'; var epoch = (new Date()).getTime(); var id = 2; var requestVars = 'GET' + epoch + resourcePath; var HexUtil = { convertByteArrayToHex : function(byteArray) { var hex = ""; byteArray.forEach(function(byteValue) { hex += HexUtil.convertByteToHex(byteValue); }); return hex; }, convertByteToHex : function(b) { var hexChar = ["0", "1", "2", "3", "4", "5", "6", "7","8", "9", "a", "b", "c", "d", "e", "f"]; return hexChar[(b >> 4) & 0x0f] + hexChar[b & 0x0f]; } }; // Compute the HMACSHA256 hash using GlideDigest var key = "key"; key = encodeURIComponent(key); key = GlideStringUtil.base64Encode(key); var msg = "message"; msg = encodeURIComponent(msg); var mac = new GlideCertificateEncryption(); signature = mac.generateMac(requestVars, "HmacSHA256", ACCESS_ID); var bytes = GlideStringUtil.base64DecodeAsBytes(signature); var hex = HexUtil.convertByteArrayToHex(bytes); var hexB64 = GlideStringUtil.base64Encode(hex); var token = 'LMv1 ' + ACCESS_ID + ':' + signature + ':' + epoch; gs.info('Devices = ' +token); var httpRequest = new GlideHTTPRequest('https://' + ACCOUNT_NAME + '.logicmonitor.com/santaba/rest/device/devices'); httpRequest.addHeader('Content-Type', 'application/json'); httpRequest.addHeader('Authorization', token); //httpRequest.addHeader('x-server-version', '3'); var response = httpRequest.getBody(); gs.log(response); Could you please help me on this.
