README

This repository is READ-ONLY. It is split automatically out of the goldene-zeiten/products monorepo, which is the single source of truth. Pull requests and commits made here are overwritten by the next split — please open them in the monorepo instead.

Shared OAuth2 client-credentials and PSR-18 HTTP plumbing used by the Products shop system's third-party API integrations (shipping carriers, payment gateways). It has no shop concepts of its own — just the token exchange, request building, and settings-layering that every REST integration would otherwise copy.

You normally do not install this directly. It is pulled in as a dependency of an integration package such as goldene-zeiten/products-shipping-ups or goldene-zeiten/products-payment-paypal.

What it provides

ApiHttpClient — a thin PSR-18 wrapper (postJson, postForm, get) that removes the stream/request/exception boilerplate and turns a transport failure into one exception type.
OAuth2ClientCredentialsProvider + OAuth2Credentials — the client-credentials token flow with per-integration token caching (each consumer wires its own cache).
ApiSettingsResolver + CurrentSiteResolver — resolve configuration by layering a system-wide extension configuration under a site's settings (empty site value inherits the default).

Installation

composer require goldene-zeiten/products-api-client

There is no site set and no editor/integrator configuration of its own.

Documentation

Developers: see Documentation/ for the public API and how a consuming package wires the token provider with its own cache.
