README

A PHP client library for interacting with the Matomo API, providing robust and extensible functionality for managing and querying Matomo analytics data.

Features

• Supports retry logic with RetryingMatomoApiClient for handling transient failures.
• Caching with Psr6CacheMatomoApiClient to minimize API calls and improve performance.
• Fully PSR-compliant with PSR-6 (Caching), PSR-3 (Logging), PSR-17 (HTTP Factories), and PSR-18 (HTTP Client).
• Extensible via the MatomoApiClientInterface for standardized requests to the Matomo API.

Installation

Install via Composer:

composer require tomkyle/matomo-api-client

Usage

Basic API Client

Class MatomoApiClient is the primary client for sending requests to the Matomo API. The API response is returned as an associative array:

use tomkyle\MatomoApiClient\MatomoApiClient;
use GuzzleHttp\Psr7\Uri;

// Initialize the client
$uri = new Uri('https://your-matomo-domain.com');
$defaults = ['token_auth' => 'your-api-token'];
$client = new MatomoApiClient($uri, $defaults);

// Send a request
$params = ['idSite' => '1', 'period' => 'day', 'date' => 'today'];
$response = $client->request($params, 'VisitsSummary.get');

print_r($response);

The Interface

All classes in this package implement the MatomoApiClientInterface interface with a request method which returns the API response as an associative array. The method accepts the Matomo API parameters as well as an optional API method—See Matomo docs for more information:

/**
 * @param  array<string,string>  $params API params
 * @return array<string|int,mixed> API result
 */
public function request(array $params, string $method = null): array;

Retrying Client

The RetryingMatomoApiClient wraps the above MatomoApiClient instance. When a request fails due to server load, it will retry the request up to a specified number of attempts.

use tomkyle\MatomoApiClient\RetryingMatomoApiClient;

// Maximum 3 attempts, 5 seconds wait
$retryingClient = new RetryingMatomoApiClient($client, 3, 5); 

// Send a request
$params = ['idSite' => '1', 'period' => 'day', 'date' => 'today'];
$response = $retryingClient->request($params, 'VisitsSummary.get');

Caching Client

The Psr6CacheMatomoApiClient wraps any MatomoApiClientInterface instance and integrates with any PSR-6 compliant cache pool.

use tomkyle\MatomoApiClient\Psr6CacheMatomoApiClient;
use Symfony\Component\Cache\Adapter\FilesystemAdapter;

$cachePool = new FilesystemAdapter();
$cachingClient = new Psr6CacheMatomoApiClient($cachePool, $client);

$response = $cachingClient->request($params, 'VisitsSummary.get');

Exceptions

• MatomoApiClientException: Thrown for errors during API requests or response handling.
