1. Klyant REST API

The Klyant REST API provides you with access to read and write data into Klyant software. In order to access the Klyant data you need to be first registered within the Klyant software application.

A registered user can use his or her credentials to access data using the REST Klyant API.

2. Security

Klyant API uses Oauth as the authentication mechanism for the API. The user will use a CliendID and Secret Key together with the login credentials to get an API token. Furthermore the API token will be the one used for further API calls.

2.1 Workflow

Use a HTTP Client appropriate for your development technology. Authenticate within the system based on user credentials. Once authenticated the http client instance will be used for future http calls within the system. This authentication requires the server to use SSL for better protection.

2.2 Example

Using Laravel Framework

In order to use the Klyant API your Laravel project needs to have at least:

"guzzlehttp/guzzle": "~4.0" in composer.json

Run composer update or composer install to update this dependency. The GuzzleHttp is a client php class library which helps you create http calls to a certain server.

Using the Klyant API means:

Step 1. Authenticate using your secret and client unique identification which can be found in Klyant under the Settings page and get your token:

$this->client = new \GuzzleHttp\Client([
 'base_url' => ''
$this->response = $this->client->post('access_token', [
 'body' => [
 'grant_type' => 'password',
 'client_id' => 'your client id',
'client_secret' => 'your client secret',
 'username' => 'Klyant login email',
 'password' => 'Klyant password'
 $token = $this->response->json();
 $this->token = $token['access_token'];

Any calls from this moment can use the authentication token:

$response = $this->client->get('v2/clients?access_token=' . $this->token);

3. API Documentation

The following methods can be called using the Klyant API:

Path Method Method Details
v2/clients?access_token= GET Load all clients or landlords
v2/client?access_token= POST Create a new client or landlord
v2/clientLedger?access_token= GET Load the client ledger card view
v2/matters?access_token= GET Load matters or properties
v2/matter?access_token= POST Create a new matter or property
v2/portfolios?access_token= GET Load all portofolios
v2/portfolio?access_token= POST Create a new portfolio


How to …


The following method can be used to authenticate a user using user email, password, client API key and secret id.

public function iSignIn ($email, $password)
  try {
  $this->response = $this->client->post('access_token', [
   'body' => [
   'grant_type' => 'password',
   'client_id' => 'client Id or API key',// can be read from environment variable
   'client_secret' => 'secret',// can be read from environment variable
   'username' => $email,
   'password' => $password
  $token = $this->response->json();
  $this->token = $token['access_token'];
} catch (GuzzleHttp\Exception\BadResponseException $e) {
  //do something with the error


$this->client = new \GuzzleHttp\Client([
   'base_url' => ''
   $this->response = $this->iSignIn('', 'mypassword');

Create a Client

The following fields can be set when you create a new client:

Field Tag Required
First_Name/td> Y
Last_Name Y
Client_Code Y
Date N (current date by default)
Is_Company (0/1) N (0 by default)
Address_1 N
Address_2 N
Address_City N
Address_Region N
Address_Country N
Address_Postcode N
PPS_Number N
Notes N
Email N
Phone N
Mobile N
Contact_Person N


Once the token is obtained via the authentication method described above a client can be created by a
code similar to the one below:

$response = $this->client->post('v2/client', [
'body' => [
'access_token' => $this->token,
'First_Name' => 'Johnny',
'Last_Name' => 'Walker',
'Client_Code' => 'WALJ001'

Retrieve All Clients

The following GET example can be used to load all clients:

$response = $this->client->get('v2/clients?access_token=' . $this->token);
 return $response->json();

Retrieve one client

The following GET example can be used to load one client uniquely identified by the Client_Code:

$response = $this->client->get('v2/client/WALJ001?access_token=' . $this->token);
 return $response->json();

Create a Property or Matter

The following fields can be set when you create a new property/matter:

Field Tag Required
Client_Account_1 Y
Client_Code Y
Date Y
Matter_Code Y
Name Y
Status (0 = Closed, 1 = Open) N (default 1)


Load All Properties or Matters

The following GET example can be used to load all matters/properties:

$response = $this->client->get('v2/matters?access_token=' . $this->token);
 return $response->json();

Data format

All results of the Klyant REST API are in json format.
In case of failure the json result contains a message explaining the failure reason and a generic status code.

Generic error codes

Here is the list of error codes and reasons why they may appear:

Code Method Reason
200 OK Successfull call.
201 Created The requested entity is succesfully created.
400 Bad Request This error usually appear when your request fails the validation (e.g. missing required fields or invalid data provided to field: specifying string for numerics etc). Consider checking the validation message or your input data.
404 Not Found The requested entity was not found in the database. Verify the id you provided or the query conditions. It also may be possible that you do not have access to that data.
500 Internal Server Error An unexpected error occurs processing your request. Please contact the Klyant administrator for support
