How to use this Interactive Documentation
This API documentation guide is interactive. On the api details page, simple enter your api and shared secret keys and you can make test api calls right from the documentation page. You can find your api keys by going to the "My Account" area when clicking on your username in the top right corner of the web portal, and then clicking on 'Manage' for your username. The documentation page constructs a valid sig for you, and automatically adds the apikey parameter to each call. You may then tweak the other parameters as desired. Required parameters are bolded, and any defaults will be pre-populated for you.How to use the APIs
The Neustar Web Performance Management (WPM) APIs are provided as a simple RESTful web service interface so that you can obtain information from and modify your account.To perform an action using the Neustar WPM APIs, you need to send an HTTP GET, POST, PUT or DELETE request to the API URL specifying your api key, a valid signature and some arguments. You will receive a json formatted response, along with a HTTP response code.
The base Neustar WPM API URL is: http://api.sec.neustar.biz/performance/ The path to the particular api endpoint that you wish to call is appended next (includes the API version number).
A Python library is available as an example at https://github.com/web-performance/wpm_api_client
Making the Request
Signing the API Call
Requests sent to the Neustar WPM API require an API key and a digital signature.A valid call is determined by validating the sig parameter at the time the request is made against the service. The value of sig is calculated by generating an MD5 or SHA256 hash made up of the API key (apikey), the API user’s shared secret, and a UNIX timestamp reflecting the number of seconds since the Unix epoch (January 1 1970 00:00:00 GMT) at the time the request is made. The system accepts timestamps up to five minutes on either side of the server timestamp, to accommodate reasonable clock drift.
NOTE: To obtain your Neustar WPM API key (apikey) and the shared secret that you need to build a digital signature, register online at https://home.wpm.neustar.biz/, then click on 'Manage Account' on the top right and go to 'Users', then click your username and your License key and password will be displayed.
Creating a Digital Signature in Code
Most programming languages provide some version of an md5() function, which should be used to generate the signature. The following example illustrates how to generate a valid signature with PHP:
$apikey = 'epuc35nesxv4bj9ww9k372rj'; $secret = 's2Q3Cx6P'; $timestamp = gmdate('U'); // 1200603038 $sig = md5($apikey . $secret . $timestamp);
The following example URL illustrates a request to the Neustar WPM API, based on an API key of ‘epuc35nesxv4bj9ww9k372rj,’ a timestamp of ‘1200603038’ (Thu, 17 Jan 2008 20:50:38 +0000), and a shared secret of ‘s2Q3Cx6P’:
http://api.sec.neustar.biz/performance/monitor/1.0?apikey=epuc35nesxv4bj9ww9k372rj&sig=65a08176826fa4621116997e1dd775fa
NOTE: Errors during the creation of the digital signature are often the reason when requests fail to authenticate and yield 403 errors. When creating the signature, be sure to:
- Use seconds since the UNIX Epoch, not milliseconds. (Some systems return the time in milliseconds. In these cases, the timestamp must be converted to seconds before being used.)
- Recalculate the digital signature with each call. (There is a 5-minute window of clock skew allowed.)
- Make sure the server calling our service is in sync with an atomic clock. It will then be in sync with our servers.
Code Samples
You can send REST requests in any programming language. The following are samples of the code for several popular languages (PHP, Python, Java, Ruby, Perl, C#, and node.js). Each example retrieves the list of all monitoring locations available for an account, uses the hosted service at api.sec.neustar.biz, and passes query parameters for an API key (apikey) and the digital signature (sig). The response is in JSON, and does not change from language to language of the request.
NOTE: This is sample code to illustrate the syntax and is not suitable for production environments. Best practices dictate that using these samples in a production environment requires error handling to catch situations where the request fails at the HTTP level.

Response Format
The response will return two things:- The general success criteria, whether success or error, is encoded into the HTTP response code, either ok (200), not found (404), forbidden (403) or some other error (5xx).
- A json response with the results if a successful query or the error messages if an error.
{ "data": { "items": [{"status": 'SUCCESS', "bytesReceived": 594936, "errorLineNumber": 0, "location": 'portland', "startTime": '2012-05-31T15:27:05', "duration": 6765, "id": 'bf5565f0ab6f11e1afe1984be166ac54' }, {...}, ... {...} ], "count": 2000, "more": true, "total": 2268, "offset": 0 } }
If the success response isn't paginated, then just the items.
{ "data": { "items": [{"alertPolicy": null, "locations": ["sanfranciscoca", "washingtondc", "portlandor"], "script": {"version": "mPHIo4TJ5nAonnZhz_16wyB5lTLC7.MX", "id": "69cc4faaac5a4bb7b880380926b08998", "name": "Grid" }, "description": "My Monitor Description", "interval": 5, "name": "API Name", "lastSampleAt", null "inMaintenanceWindow": false, "active": false, "type": "full", "id": "8725440e931711e1b459000c299f6329", "browser": "chrome" }, {...}, ... {...} ] } }
The error response should always contain the message, code and param keys, but additional are optional.
{ "errors": [{ "message": "The item could not be found", //A string providing details on what the error was. "code": "NAMESPACE-40", //Identifies which error occurred. "param": "FAILED_PARAMETER" //Optional - A string indicating which field(s) had the failure, if it was a field error. // other optional }] }
Error Codes
If a request fails, then both an HTTP status coding indicating the general failure condition as well as a detailed error message are produced. The error code is a machine readable status which will never change, where the text of the error message might change due to changing inputs or other factors. A list of these codes and messages is shown below.
