README

PHP client for the Deutsche Post DHL Internetmarke API.

Documentation

This repository provides:

HTTP client and service-layer classes to call the Internetmarke API. See documentation: AppResource, ApiVersionResource, UserResource.
DTO models for request/response payloads.
Token provider for OAuth-like authentication.
PHPUnit tests.

Highlights of recent changes

Base URI for requests is centralized in ClientConfig
ApiClient implements ApiClientInterface.
TokenProvider implements TokenProviderInterface.
AuthenticationRequest DTO introduced and used by TokenProvider and UserResource.
Tests were updated to use ClientConfig('') to avoid automatic base URI prefixing during unit tests.
Several classes and tests were adapted to be more testable and type-safe.
added Makefile for common tasks (install, test, etc.)
added Internetmarke facade for easy setup and usage.

Requirements

PHP 8.1+ (or the project's required PHP version)
Composer
client (provided via composer)
PHPUnit (dev dependency)

Installation

Use the included Make targets to install dependencies:

# install PHP dependencies
make install

(If you prefer running composer directly, composer install is equivalent.)

Usage

The simplest way to get started is to use the Internetmarke facade class, which handles configuration, token provision, and API client setup for you:

use Maxs94\Internetmarke\Internetmarke;

$internetmarke = new Internetmarke(
    'your-client-id',
    'your-client-secret',
    'your-username',
    'your-password'
);

// get API version information
var_dump($internetmarke->getApiVersionResource()->getVersion());

// walletBalance can be retrieved from the tokenProvider,
// as DHL includes it in the authentication response
var_dump($internetmarke->getTokenProvider()->getAuthentication()->getWalletBalance());

// get user profile
var_dump($internetmarke->getUserResource()->getUserProfile());

Creating a label

To create and checkout a label, see the AppResource documentation for details and code examples.

Testing

Run the test suite with the Make targets:

# or explicitly run phpunit
make phpunit

# run static analysis
make phpstan

# fix coding standards issues
make csfix

Development notes

Prefer ClientConfig for all places where a base URI must be configured — it centralizes the setting.
The ApiClientInterface and TokenProviderInterface allow you to provide your own implementations for special cases (e.g. custom HTTP adapters, testing).
If you need to mock the token provider or API client in tests, mock the interface types (TokenProviderInterface and ApiClientInterface) instead of final concrete classes.

Contributing
