API Client Documentation

Welcome to The Marketer API Client docs.

This documentation is for teams integrating the PHP package themarketer/api-client.

Official theMarketer API Reference — HTTP endpoints, parameters, and flows for the same platform APIs this client wraps: developers.themarketer.com/reference (the developer portal home redirects here). Use it alongside these docs for staging setup, endpoint details, and topics such as testing on a staging environment.

Most integrations start with:

• authenticating the client
• initializing the modules you use (orders(), events(), etc.)
• handling validation and API errors

The Client is constructed with an associative array (customerId, restKey, trackingKey, plus optional URLs and maxRetryAttempts). See Authentication.

Common first call

$ok = $client->checkApiCredentials();

if (!$ok) {
    // handle invalid credentials
}
