WAPI Manual

  WAPI (API Interface)

In this article, you will learn:

WEDOS API

The WEDOS API, also called WAPI, is used to manage services directly from your own information system.

To use WAPI, you need an active credit account, from which the system deducts payments for domain registrations, renewals, transfers and other charges.

WAPI currently supports the management of:

Restrictions

To prevent misuse, we apply the following restrictions to WAPI:

  • One user account can send a maximum of 1000 requests per hour. This applies to all types of requests. When this limit is reached, WAPI rejects further requests until the timeout expires.
  • One user account is allowed to make a maximum of 100 domain availability requests per hour. This applies to the domain-check, domain-create and domain-transfer-check requests.
  • Repeated invalid requests (authorization failure, access from an unauthorized IP address, incorrect input, missing or incorrect parameters, unknown commands, commands resulting in any error, or any request beyond other restrictions) will cause the IP address to be blocked for 1 minute for each invalid request in excess of 10. With each additional invalid request, the system increases the blocking time.

Synchronous and Asynchronous Requests

Most of the requests executed via WAPI are synchronous – you send the request and you usually get the result within a few seconds.

Some requests are asynchronous – processing such requests can take a very long time (even hours or days). In such cases, WAPI doesn’t return the final result, but only information about receiving the request. The system then sends you information about the progress and the final result in the form of notifications.

WAPI Activation

Before you start using WAPI, activate it in the customer administration by following these steps:

  1. Log into the customer administration panel.
  2. In the navigation bar, select My Account Customer.
  3. In the left menu, select WAPI Interface.
  4. Set up allowed IPs, a notification method, a preferred protocol and a password.
  5. Confirm by clicking the Set button.

You can change all these settings later in the same way. To disable WAPI entirely, delete the contents of the Allowed IPs field.

Communication and Authentication

Communication with the WAPI interface takes place via the HTTPS protocol. Data is passed by the POST method in the request parameter in XML or JSON format. The basic structure of both the request and response is the same for all commands. Data encoding is UTF-8.

The interface URLs are:

  • XML: https://api.wedos.com/wapi/xml
  • JSON: https://api.wedos.com/wapi/json

Request Structure

The request consists of the following data:

  • user: Your WEDOS customer account login (email), required.
  • auth: Authorization string, required. This is a sha1 hash of a string composed of the username, the sha1 hash of the WAPI password and the current time (00-23). The time zone is Europe/Prague (UTC+1 CET, or UTC+2 CET with DST adjustment). See code below for a specific example.
  • command: The actual WAPI request. Required.
  • clTRID: Request ID, optional. You can put any string in this element as an identifier that WAPI will return in the response.
  • data: The data part of the request. Optional.
  • test: Test mode flag, optional. If you include a test element with a value of 1 in the request, WAPI will only check the command, but not make any changes in the system.

Enter the WAPI password when communicating with WAPI. The customer account password does not work.

  "request":
  {
    "user": "your@login.tld",
    "auth": "auth-string",
    "command": "request-name",
    "data":
    {

PHP Template (JSON)

The following sample script requires the curl extension to run.

<?php 
date_default_timezone_set('Europe/Prague'); 
$login = 'your@login.tld'; 
$wpass = 'your-WAPI-password'; 
$auth = sha1($login.sha1($wpass).date('H', time())); 
$url = 'https://api.wedos.com/wapi/json'; 
$input = [ 'request' => [
  'user' => $login,
  'auth' => $auth,
  'command' => 'request-name',
  'data' => ['request-data'],
  'clTRID' => 'request-id (optional)',
  'test' => '1 (if you want to test the request only)'
  ]
];

$post = json_encode($input);
$ch = curl_init($url);
curl_setopt($ch,CURLOPT_TIMEOUT,60);
curl_setopt($ch,CURLOPT_POST,true);
curl_setopt($ch,CURLOPT_POSTFIELDS, 'request=' . $post);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type: application/x-www-form-urlencoded']);
$res = curl_exec($ch);
?>

PHP example:

<?php 
date_default_timezone_set('Europe/Prague');
$login = 'your@login.tld';
$wpass = 'your-WAPI-password';
$auth = sha1($login.sha1($wpass).date('H', time()));
$url = 'https://api.wedos.com/wapi/json';
$input = [ 'request' => [
'user' => $login,
'auth' => $auth,
'command' => 'request name',
'data' => ['request data'],
'clTRID' => 'request identifier',
'test' => '1 (if you only want to test the request)'
]
];

$post = json_encode($input);
$ch = curl_init($url);
curl_setopt($ch,CURLOPT_TIMEOUT,60);
curl_setopt($ch,CURLOPT_POST,true);
curl_setopt($ch,CURLOPT_POSTFIELDS, 'request=' . $post);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type: application/x-www-form-urlencoded']);
$res = curl_exec($ch);
?>

Response Structure

The response consists of the following data:

  • code: The return code for the given request. You can find more information in the chapter Return Codes.
  • result: Return code description.
  • timestamp: Command execution time in UNIX format.
  • clTRID: Client’s request identifier.
  • svTRID: Server’s request identifier.
  • command: WAPI request.
  • data: Return data. None if the request fails.
  • test: Included with responses for test requests.

A sample JSON response looks like this:

{
  "response":
  {
    "code": "1000",
    "result": "ok",
    "timestamp": "1286356644",
    "svTRID": "1286356644.0246.21616",
    "command": "domain-create",
    "data": 		
    {
      "num": "1311000863",
      "expiration": "2011-10-06"	
    },
    "test": "1"
  }
}

Notifications

Asynchronous requests cannot be performed immediately. You can monitor the progress and result of such operations through notifications. Synchronous requests do not use notifications.

If WAPI cannot complete the operation immediately, it returns Request pending (1001) in response. After the operation is completed (for more complicated actions of individual steps), it creates a notification that is similar to a classic response. You can match the notification to the corresponding request using the clTRID or svTRID parameters.

Notification data is always encoded in UTF-8.

You can receive notifications in the following ways (according to the settings):

  • Using the POLL queue.
  • Send to specified email address.
  • Via HTTP (or HTTPS) protocol to the URL address specified by you using the POST method in the request parameter. An HTTP response with a return code of 200 is considered a success. If delivery fails, the system will attempt to deliver the notification againat several-minute intervals.

A sample notification in JSON format looks like this:

{
"notify": {
"code": 1000,
"result": "OK",
"timestamp": 1286957932,
"svTRID": "1286957874.1271.15706",
"command": "ping-async",
"ID": 2691
}
}

System Notifications

System notifications send information about relevant events, currently only about domain transfers to another registrar. If you have an active WAPI for your account, the system sends such information using notifications, similar to an asynchronous command.

Set the protocol in which WAPI sends system notifications in the customer administration panel according to the chapter WAPI Activation. This option works for notifications sent to an email or URL address. In the case of downloading from the POLL queue, the response is in the same form as the command.

The structure is the same as a classic notification, the command is always system-notify. You will then find more detailed information in the data node.

Basic Requests

Basic requests include ping, ping-async, and commands for working with the POLL queue poll-req and poll-ack.

poll-req and poll-ack

You can receive notifications from the POLL queue by combining poll-req and poll-ack commands:

  1. Use the poll-req command to download the oldest available notification.
  2. With the poll-ack command, mark the notification as read and make newer ones available until the queue is exhausted.

The return values for poll-req are:

  • 1000 – notification received
  • 1003 – no unread notification in queue
  • 2150 – poll queue notifications disabled for this account
