Everything you need to know about using the Tectalic WP Engine PHP API Client.
The Tectalic WP Engine REST API Client is a package that provides a convenient and straightforward way to interact with the WP Engine API from your PHP application.
You can purchase this package from https://tectalic.com/apis/wp-engine.
To install this package into your PHP project, we recommend using Composer.
Please see the detailed instructions on configuring your project to access the Tectalic Composer repository.
You will need to log into the Tectalic account that purchased the Tectalic WP Engine REST API Client package to access these instructions.
Once you have followed the above instructions, install the package into your project:
composer require tectalic/wp-engine
If you aren’t using Composer in your PHP project, you can choose to Download the latest release and install it into your PHP project manually.
If doing this, you will need to ensure that all dependencies listed in the package’s composer.json
file are also installed.
After installing the Tectalic WP Engine REST API Client package into your project, ensure you also have a compatible PSR-18 HTTP client such as ‘Guzzle’ or the Symfony ‘HTTP Client’.
You can use the following code sample and customize it to suit your application.
// Load your project's composer autoloader (if you aren't already doing so).require_once(__DIR__ . '/vendor/autoload.php');
use Symfony\Component\HttpClient\Psr18Client;use Tectalic\WpEngine\Authentication;use Tectalic\WpEngine\Client;use Tectalic\WpEngine\Manager; // Build a Tectalic WP Engine REST API Client globally.$auth = new Authentication('username', 'password');$httpClient = new Psr18Client();Manager::build($httpClient, $auth); // or // Build a Tectalic WP Engine REST API Client manually.$auth = new Authentication('username', 'password');$httpClient = new Psr18Client();$client = new Client($httpClient, $auth, Manager::BASE_URI);
To authenticate your API requests, you will need to provide an Authentication
($auth
) object when calling Manager::build()
.
Authentication to the WP Engine API is by HTTP Basic authentication.
API username and password from Portal’s API Access page: https://my.wpengine.com/api_access
Please see the WP Engine API documentation for more details on obtaining your authentication credentials.
In the Usage code above, customize the Authentication
constructor to your needs. For example, you may wish to define your credentials in an environment variable and pass it to the constructor.
The primary class you will interact with is the Client
class (Tectalic\WpEngine\Client
).
This Client
class also contains the helper methods that let you quickly access the 12 API Handlers.
Please see below for a complete list of supported handlers and methods.
This package supports 32 API Methods, which are grouped into 12 API Handlers.

There are two ways to make a request to the nominated API Handler and API Method:
If you built the client to be accessible globally, you can use the relevant API Handler Class directly:
use Tectalic\WpEngine\Handlers\Accounts; (new Accounts())->list();
Alternatively, you can access all API Handlers from the client class using the Client class:
$client->accounts()->list();
Once you have made a request using one of the two methods outlined above, the next step is to access the response.
You can access the response in different ways. Please choose your preferred one.
Model responses are Data Transfer Object (DTO) style PHP classes, with public properties for each API property.
They offer a structured way of retrieving the response from an API request.
All Response Models are an instance of Tectalic\WpEngine\Models\AbstractModel
or Tectalic\WpEngine\Models\AbstractModelCollection
.
After performing the request, use the ->toModel()
fluent method to the API Method:
use Tectalic\WpEngine\Handlers\Accounts; $model = (new Accounts())->list()->toModel();
Each API Method’s toModel()
call will return the appropriate Model class type for the API Method you have just called.
After performing the request, use the ->toArray()
fluent method to the API Method:
use Tectalic\WpEngine\Handlers\Accounts; $array = (new Accounts())->list()->toArray();
In the resulting associative array, the array keys will match the names of the public properties in the relevant Model class.
If you need to access the raw response or inspect the HTTP headers, use the ->getResponse()
fluent method to the API Method. It will return a Psr\Http\Message\ResponseInterface
:
use Tectalic\WpEngine\Handlers\Accounts; $response = (new Accounts())->list()->getResponse();
When performing requests with Tectalic WP Engine REST API Client, specific scenarios will cause a Tectalic\WpEngine\Exception\ClientException
to be thrown. Please see below for details.
Manager
ClassA \LogicException
will be thrown if the Manager::build()
function is called multiple times, or if Manager::access()
is called before calling Manager::build()
.
The Tectalic WP Engine REST API Client depends on a PSR-18 compatible HTTP client, and that HTTP client should not throw an exception for unsuccessful HTTP response codes.
An unsuccessful response code is classified as one that is not in the range 200
-299
(inclusive). Examples of unsuccessful response codes include:
100
-199
)300
-399
)400
-499
)500
-599
)If an unsuccessful response code does occur:
toModel()
method will throw a ClientException
.toArray()
method will return the response body and not throw a ClientException
.getResponse()
method will return the raw response and not throw a ClientException
.Below is an example of how you may wish to use a try
/catch
block when performing a request so that you can detect and handle unexpected errors.
use Tectalic\WpEngine\Authentication;use Tectalic\WpEngine\Client;use Tectalic\WpEngine\ClientException;use Tectalic\WpEngine\Manager; // Build a Tectalic WP Engine REST API Client globally.$auth = new Authentication('username', 'password');Manager::build($httpClient, $auth);$handler = new Accounts(); // Perform a requesttry { $model = $handler->list()->toModel(); // Do something with the response model...} catch (ClientException $e) { // Error response received. Retrieve the HTTP response code and response body. $responseBody = $handler->toArray(); $rawResponse = $handler->getResponse()->getResponse(); $responseCode = $handler->getResponse()->getStatusCode(); // Handle the error...}
If your HTTP client of choice throws an exception other than ClientException
, the Tectalic WP Engine REST API Client Client
and its API Handler classes will let these exceptions bubble up.
Consult your HTTP client’s documentation for more details on exception handling.
The Tectalic WP Engine REST API Client package includes several types of automated PHPUnit tests to verify the correct operation:
To run these tests, you will need to have installed the Tectalic WP Engine REST API Client package with its dev dependencies (i.e. not using the --no-dev
flag when running composer).
These PHPUnit tests are designed to:
Client
and Manager
classes.The unit tests can be run using the following command, which needs to be run from this package’s root directory.
composer test:unit
Unit tests do not perform any real requests against the WP Engine API.
Unit tests are located in the tests/Unit
directory.
Integration tests are located in the tests/Integration
directory.
These PHPUnit tests are designed to confirm that each API Method parses a valid response, according to the WP Engine API OpenAPI specification. Out of the box the integration tests are designed to work with the Prism Mock Server.
Make sure Prism is installed. Please see the Prism documentation for details on how to install Prism.
Once Prism is installed, you can run prism and the integration tests side by side in separate terminal windows, or using the following command, which need to be run from this package’s root directory.
echo "> Starting Prism server"prism mock tests/openapi.yaml >/dev/null 2>&1 &PRISM_PID=$!sleep 2echo " => Started"composer test:integrationkill $PRISM_PID
Those commands will start the Prism mock server, then run the integration tests, and then stop the Prism mock server when the tests are completed.
In this case the integration tests do not perform any real requests against the WP Engine API.
By setting the WP_ENGINE_CLIENT_TEST_BASE_URI
environment variable, you can set a different API endpoint target for the integration tests.
For example, instead of using Prism, you can use a different mocking/staging/test server of your choice, or you can use the WP Engine API’s live endpoints.
Do not forget to set the appropriate credentials in the WP_ENGINE_CLIENT_TEST_AUTH_USERNAME
WP_ENGINE_CLIENT_TEST_AUTH_PASSWORD
environment variables.
After your setup is complete simply run the following command.
composer test:integration
We do not recommend running integration tests against the live WP Engine API endpoints. This is because the tests will send example data to all endpoints, which can result in new data being created, or existing data being deleted.
If you are writing your own tests, you will likely need to mock the responses from the WP Engine API.
One way of doing this is to install the php-http/mock-client
package into your project, and then use the \Http\Mock\Client
class (instead of a real PSR-18 client) when instantiating the Tectalic WP Engine REST API Client.
This allows you to mock the responses from the WP Engine API, rather than performing real requests.
Please see the Mock Client documentation for details.
