} catch (RateLimitException $e) {
    // 429 — back off and retry
} catch (ApiException $e) {
    echo $e->httpStatus; // 4xx / 5xx
    echo $e->rawBody;
} catch (ProtocolException $e) {
    // response received but could not be parsed (malformed JSON from API)
} catch (NetworkException $e) {
    // curl / transport error
}

Configuration

$client = new Client(
    apiKey:         'key',
    connectTimeout: 10,   // seconds, default
    requestTimeout: 30,   // seconds, default
);

Custom HTTP client (PSR-18)

use Sendpulse\RestApi\Http\Adapter\Psr18Adapter;

$client = new Client(

    httpClient: new Psr18Adapter(
        client:         $yourPsr18Client,
        requestFactory: $requestFactory,
        streamFactory:  $streamFactory,
    ),
);

Custom token storage

use Sendpulse\RestApi\Token\Psr16TokenStorage;
use Sendpulse\RestApi\Token\InMemoryTokenStorage;

// PSR-16 cache (e.g. Symfony Cache, Laravel Cache)
$storage = new Psr16TokenStorage($psr16Cache);

// In-memory (tokens lost on process exit)
$storage = new InMemoryTokenStorage();

$client = new Client(
    clientId:     'id',
    clientSecret: 'secret',
    tokenStorage: $storage,
);
