The Marketer API Client (PHP)

PHP client for the The Marketer API. It sends HTTP requests via Guzzle (the internal ApiGateway class) and validates payloads with Symfony Validator (the AbstractPayload / Data DTOs from TheMarketer\ApiClient\Common).

Client documentation

For a structured, easy-to-follow version:

• API Client Docs

Docusaurus site (GitHub Pages)

The documentation is also available as a Docusaurus site in the website/ folder.

Run locally:

cd website
npm install
npm run start

Deployment to GitHub Pages is configured through the workflow:

• .github/workflows/deploy-docs.yml

Architecture at a glance

• TheMarketer\ApiClient\Client — single entry point: takes a configuration array (customerId, restKey, optionally trackingKey, restUrl, trackingUrl, maxRetryAttempts), builds Config + ApiContext and exposes the API modules (subscribers(), orders(), checkCredentials(), etc.).
• ApiContext — provides the REST gateway (ApiGateway) and the tracking gateway (TrackingGateway); both use Guzzle (configurable retry).
• ApiGateway — for REST: k (rest key) and u (customer id) query params; JSON on POST where the DTO requires it; maps HTTP errors to exceptions.
• TrackingGateway — for the tracking host: requires trackingKey in the config; a different set of authentication parameters in the query.
• The classes in src/Api/ — encapsulate the endpoints; input validation happens in src/DTO/.

The base URL for REST is Config::baseRestUrl() = {restUrl}/api/{apiVersion}/ (default apiVersion = v1). The default URLs live in Client / Config (src/Common/Config.php).

Basic usage

use TheMarketer\ApiClient\Client;

$client = new Client([
    'customerId' => 'THE_MARKETER_ACCOUNT_ID', // query `u` on REST
    'restKey' => 'REST_KEY',                    // query `k` on REST
    'trackingKey' => 'TRACKING_KEY',            // optional: for tracking events
    'maxRetryAttempts' => 1,                     // optional
]);

// Examples of accessing the grouped APIs
$client->subscribers()->addSubscriber([/* … */]);
$client->orders()->saveOrder([/* … */]);
$client->transactionals()->sendEmail([/* … */]);

Credentials and utilities (directly on Client)

These methods do not go through subscribers() / orders(); they are delegated to the internal CredentialsClient.

checkCredentials(string $trackingKey): bool

Checks the credentials (tracking key in the JSON body on REST, see CredentialsClient). On Client, it returns true if the decoded response is an empty array [], otherwise false. For the raw JSON as an array, use CredentialsClient::checkCredentials() with the same context.

$ok = $client->checkCredentials('TRACKING_KEY');

checkApiCredentials(): bool

On Client, it returns a bool (same criterion: JSON body → empty array = success). For the full decoded response, see CredentialsClient::checkApiCredentials().

$ok = $client->checkApiCredentials();

getCosts(), getRealtimeVisitors(), getSmsCredit(): array

Decoded JSON response.

getReferralLink(?string $email = null): string

Returns the raw content of the response (not JSON).

getDeliveryLogs(array $payload): array

email required; optional: per_page, page, start, end.

getEnteredAutomation(array $payload): array

date required (Y-m-d); optional page, perPage.

config(): Config

Access to customerId, restKey, baseRestUrl(), trackingKey(), etc.

API modules (examples)

Accessor on Client	Role
subscribers()	Subscribers: status, add/remove, bulk, tags, etc.
orders()	Orders, feed URL, retail, statistics
transactionals()	Transactional email and SMS
products()	Product CRUD / sync, categories, brands
campaigns()	List, create campaign, email report, last campaign
loyalty()	Loyalty points
coupons()	Available coupons, saving
reviews()	Product and merchant reviews, Merchant Pro settings
mobilePush()	Mobile push (iOS/Android tokens)
events()	Custom events
reports()	Email/SMS/push/forms/audience reports

Details about parameters: the files in src/Api/*Api.php and src/DTO/**. The tests in tests/*ApiTest.php show examples of valid payloads.

Campaigns — important notes

• list() uses POST to /campaigns/list, with the body from ListCampaign.
• create() requires a nested structure validated by CreateCampaign; for the sender it uses the keys name, sender (email), reply_to (not sender_name / sender_email).

Reviews

• getProductReviews() returns a string (raw response content, not an automatically decoded array).

Reports

• Queries usually include start, end, type (see the enums in src/Enum/ and the DTOs in src/DTO/Reports/).

---

Errors and exceptions

Before the request (local validation)

• TheMarketer\ApiClient\Exception\ValidationException — missing customerId / restKey in the config, or messages from Symfony validation on the DTO.
• Missing required arguments when building a DTO can lead to ArgumentCountError or TypeError before any network call.

After the request (ApiGateway maps the HTTP status)

Status	Exception
401	UnauthorizedException
404	CustomerNotFoundException
405	MethodNotAllowedException
Other errors	ApiException (uses the code and message from the response; the message is extracted from the JSON message when present)

On a successful response with invalid JSON, the methods that decode it can throw JsonException. For network errors: GuzzleHttp\Exception\GuzzleException.

---

Tests

composer test

The suite uses ApiGateway with a Guzzle MockHandler (no real API calls). For Client in tests with an HTTP mock, context is readonly; in practice CredentialsClient and the *Api classes are tested with the same stack — see tests/CredentialsClientTest.php and tests/TestCase.php.

---

Smoke script (smoke.php)

A quick check with real credentials (do not commit keys to the repo):

php smoke.php

The example in the repo calls checkCredentials($trackingKey) — replace the values with the ones from your The Marketer account.
