Request Parameters

Parameter Description

Parameter	Description
StartTime	Only show notifications that were issued on this date/time or later, given as an ISO-8601 date/time string, like `YYYY-MM-DDTHH:MM:SS` (for example `2018-10-05T22:45:32`) or, if you want to omit the time, YYYY-MM-DD (for example `2018-10-05`). When only a date is provided the time is assumed to be at midnight of the given date. Note that the given date/time is inclusive and is assumed to be in UTC timezone.
EndTime	Only show notifications that were issued on this date/time or earlier, given as an ISO-8601 date/time string, like `YYYY-MM-DDTHH:MM:SS` (for example `2018-10-06T02:10:03`) or, if you want to omit the time, YYYY-MM-DD (for example `2018-10-06`). When only a date is provided the time is assumed to be at midnight of the given date. Note that the given date/time is inclusive and is assumed to be in UTC timezone.
ErrorCode	Only show notifications that returned this Error Code
RequestUrl	Only show notifications that have this RequestUrl

   -u "YourAccountSid:YourAuthToken"

const request = require('request');

// Provide your Account Sid and Auth Token from your Console Account page
const ACCOUNT_SID = 'my_ACCOUNT_SID';
const AUTH_TOKEN = 'my_AUTH_TOKEN';

request({
      method: 'GET',
      url: 'https://mycompany.restcomm.com/restcomm/2012-04-24/"Accounts/' + ACCOUNT_SID + '/Notifications.json?SortBy=DateCreated:asc',
      auth: { 'user': ACCOUNT_SID, 'pass': AUTH_TOKEN },
   },
   function (error, response, body) {
      // Add your business logic below; status can be found at 'response.statusCode' and response body at 'body'
      ...
   }
);

from http.client import HTTPSConnection
from base64 import b64encode

# Provide your Account Sid and Auth Token from your Console Account page
ACCOUNT_SID = 'my_ACCOUNT_SID'
AUTH_TOKEN = 'my_AUTH_TOKEN'

userAndPass = b64encode(bytes(ACCOUNT_SID + ':' + AUTH_TOKEN, 'utf-8')).decode("ascii")
headers = { 'Authorization' : 'Basic %s' %  userAndPass }

conn = HTTPSConnection('mycompany.restcomm.com')
conn.request("GET", '/restcomm/2012-04-24/"Accounts/' + ACCOUNT_SID + '/Notifications.json?SortBy=DateCreated:asc',
      headers=headers)
res = conn.getresponse()

// Add your business logic below; status can be found at 'res.status', reason at 'res.reason' and response body can be retrieved with res.read()

The result of the SortBy parameter:
