Summary by CodeRabbit

  • New Features
    • Added a unified way to create clients with token, OAuth2, or Basic authentication.
    • Authentication is applied per request, and request-specific authorization headers can override configured credentials.
    • Added an option to allow credentials over plain HTTP; by default, credentials require HTTPS except for loopback connections.
    • Added a custom HTTP client cookbook example and updated impersonation examples to keep impersonation scoped to a separate client.
  • Bug Fixes
    • Empty or whitespace-only required credentials are rejected, and sensitive credentials are redacted from debug output.
  • Documentation
    • Refreshed setup, framework, and migration guidance to reflect the current client configuration approach.

📝 Walkthrough

The change adds the immutable Auth value object for token, OAuth2, and Basic credentials. RequestHandler applies configured authentication per request while allowing request-specific headers to override it. ZammadClient::create() provides authenticated client construction. Guzzle, Laravel, and Symfony integrations use the new API. Documentation, migration guides, cookbook examples, tests, and changelog entries are updated.

Priority: ⬇️ Low

Merge Risk: 🔵 Low · up to bf4dc

Users following the no-Flex custom Symfony setup cannot resolve the PSR-17 factory until its service ID is aligned. The issue is limited to that configuration and has a straightforward fix, so the remaining merge risk is low.

Define the service ID used by the custom handler.

If Flex did not install the Nyholm recipe, the suggested declaration creates Nyholm\Psr7\Factory\Psr17Factory. The handler at Line 137 requests nyholm.psr7.psr17_factory instead. Symfony cannot resolve that reference. Declare the factory under the referenced ID, or change the handler reference to the class service ID. (github.com)

Trim credentials before validation, so a whitespace-only token is
rejected like an empty one, and document that a token is required.

Drop the @deprecated notices on GuzzleClientFactory::with*() and on
SerializesToArray::id(). Both promised removal in v4.0, but there is no
v4 milestone, issue or roadmap, and the project has no deprecation or
versioning policy at all — the v2 to v3 bump removed APIs with no
deprecation period whatsoever. Nor is there a reason to remove them: the
helpers are four-line delegations to Auth that cost no maintenance, and
id() is required by DTOInterface and called by Resource itself, so the
marker contradicted a live contract and the library's own usage.

ZammadClient::create() remains the recommended entry point; that is said
in the class docblock, the README and the CHANGELOG instead of by a
removal date the project cannot keep.

Fix three defects found in review:

SymfonyBundle registered the client with ContainerBuilder::set(), which
stores a live instance. Instances set that way do not survive container
compilation, so injecting ZammadClient failed the build with "non-existent
service" — the bundle never worked in a compiled container. It now
registers a lazy Definition with ZammadClient::create() as its factory and
an inlined Auth definition, resolving %env(ZAMMAD_TOKEN)% at runtime so
the token stays out of var/cache. Verified by compiling and dumping a
container against symfony/dependency-injection 7.4 outside this repo,
since src/Bridge/ has no tests and no static analysis (#169).

The password parameters of Auth::basic() and withBasicAuth() are marked
#[\SensitiveParameter]. An empty username throws from inside basic(), so
with PHP's default zend.exception_ignore_args=0 the password appeared
verbatim in the stack trace. Covered by a regression test that skips on
PHP 8.1 and when the ini strips arguments.

The Symfony service IDs in the custom HTTP client guide were class names
rather than registered services, so copying that YAML failed the build.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
RequestHandler attached the Authorization header to every request without
ever looking at the URL scheme, so an http:// base URL put the token on the
wire for anyone on the path to read.

Constructing a handler with an Auth and a plain http:// URL whose host is
not loopback now throws an InvalidArgumentException. Loopback is exempt --
localhost, any .localhost name, the whole 127.0.0.0/8 range and ::1 -- so
every default this project ships keeps working. Where the connection is
protected by other means, ConnectionConfig(allowInsecureHttp: true) opts
out, and the exception message says so.

The check sits in the constructor, not in dispatch(): $baseUrl is fixed for
the lifetime of the handler and every request method funnels through
dispatch(), so checking once covers all of them.

It keys on the Auth it is handed, which leaves one case uncovered: a PSR-18
client that sets the header itself, as the custom-transport guide suggests
for runtime-refreshed credentials. That header is invisible from here. The
docblock, the guide and the changelog say so rather than implying the guard
is complete.

Breaking for anyone pointing the client at a remote Zammad over plain HTTP.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Pins down both halves of the new check: that it fires on a non-loopback
http:// URL with credentials, and that it stays out of the way everywhere
else -- https://, loopback in all four spellings (localhost, .localhost
subdomain, 127.0.0.0/8 beyond 127.0.0.1, and ::1), and a handler built
without an Auth at all.

The last one is the documented gap, so it gets a test of its own: the guard
cannot see a header the PSR-18 client adds, and a future reader should find
that stated rather than inferred.

Two more go through GuzzleClientFactory, because allowInsecureHttp has to
travel ConnectionConfig -> factory -> handler before ZammadClient::create()
can reach it. Without them that wiring is untested.

CreatesRequestHandler gains $baseUrl and $allowInsecureHttp parameters; its
BASE_URL default is unchanged, so no existing test is affected.

The Symfony section of the custom HTTP client guide offered the create()
definition and a custom PSR-18 stack in one services: block, with the
custom stack under its own app.zammad_client ID. Autowiring resolves a
ZammadClient type-hint to the ZammadAPIClient\ZammadClient ID, so anyone
copying that block got the Guzzle client and a dead custom stack. Verified
by compiling both variants against symfony/dependency-injection: before,
a consumer type-hinting ZammadClient received GuzzleHttp\Client even with
the custom stack defined; now it receives the custom PSR-18 client. They
are two clearly alternative blocks, both registering the class ID -- the
shape SymfonyBundle already uses -- with a note to drop the bundle, since
it registers the same ID.

The Slim recipe told readers to create a .env and then read $_ENV without
loading one. Slim ships no dotenv loader, and $_ENV is empty altogether
unless php.ini's variables_order includes E. It now uses getenv(), like
every other recipe, and says where the variables are expected to come from
in a web app. 08-laravel.php keeps its .env line: Laravel does load it.

The v3 migration guide allowed ^3.0 while the instantiation shown directly
below it calls ZammadClient::create(), which exists from 3.2.0 on.

Also documents the new cleartext guard where credentials are introduced --
README, the custom HTTP client guide and the ConnectionConfig table -- and
changes the cookbook's example URL, which used a non-loopback http:// host
the guard now rejects.

The custom-stack YAML references '@nyholm.psr7.psr17_factory', but the
fallback for installations without the Flex recipe declared the service
under its class name instead. A reader following it hit exactly the error
the surrounding paragraph exists to prevent:

  The service "app.zammad_request_handler" has a dependency on a
  non-existent service "nyholm.psr7.psr17_factory".

The reference is explicit, so autowiring does not bridge the two IDs. The
fallback now declares the ID the handler actually asks for.

Verified by compiling the snippets extracted from this file against
symfony/dependency-injection with nyholm/psr7 installed and no Flex-provided
service present: the previous fallback failed with the error above, the new
one compiles and yields Nyholm\Psr7\Factory\Psr17Factory.
