Adds CRUD for an inbox's forward rules and a search parameter on the threads list. Responses are returned as-is, so the new forwards on messages and delivery on sent thread messages are available without SDK changes.

Changes

  • Api\Inbound\ForwardRule with getList, getById, create, update and delete, registered as forwardRules in MailtrapInboundClient
  • CreateInboundForwardRule, UpdateInboundForwardRule, InboundForwardRuleCondition and InboundForwardRuleDestination DTOs, plus an InboundForwardRule vocabulary class holding MATCH_TYPE_* / OPERATOR_*
  • Thread::getList takes an optional $search, combinable with $lastId
  • Forward rules example and entries in both README tables

Summary by CodeRabbit

  • New Features
    • Added search support for inbound email threads, with optional filtering by search term.
    • Added tools to list, create, retrieve, update, and delete inbox forwarding rules, including configurable matching conditions and destinations.
    • Added examples demonstrating thread search and forwarding-rule management.

📝 Walkthrough

Walkthrough

The inbound client adds forward-rule CRUD operations and request DTOs. Thread listing adds an optional search parameter. Examples, README entries, and tests cover these additions and inbound forwarding and delivery response fields.

Changes

Inbound forward-rule management

Layer / File(s) Summary
Forward-rule request contracts
src/DTO/Request/Inbound/InboundForwardRule.php, src/DTO/Request/Inbound/InboundForwardRuleCondition.php, src/DTO/Request/Inbound/InboundForwardRuleDestination.php, src/DTO/Request/Inbound/CreateInboundForwardRule.php, src/DTO/Request/Inbound/UpdateInboundForwardRule.php
The new request DTOs define allowed condition values and serialize rule names, conditions, destinations, and partial updates. Conditions reject unsupported match types and operators.
Forward-rule API and client integration
src/Api/Inbound/ForwardRule.php, src/MailtrapInboundClient.php, tests/Api/Inbound/ForwardRuleTest.php, tests/MailtrapInboundClientTest.php
The inbound client exposes inbox-specific forward-rule list, retrieve, create, update, and delete operations. Tests cover API calls, payload serialization, validation, and client mapping.
Forward-rule examples and documentation
examples/inbound/forward-rules.php, README.md, examples/README.md
The example demonstrates forward-rule CRUD. The README entries add forward-rule CRUD and thread search to the inbound examples.

Thread search and response coverage

Layer / File(s) Summary
Thread search and response tests
src/Api/Inbound/Thread.php, examples/inbound/threads.php, tests/Api/Inbound/ThreadTest.php, tests/Api/Inbound/MessageTest.php
Thread listing accepts an optional search term independently of the last_id cursor. Tests cover search query parameters and inbound forwarding and outbound delivery response fields.

Confirm the in-app code examples.

This change adds a public example for forward-rule client initialization and method calls. The Mailtrap app shows equivalent code examples to users. Confirm whether the in-app examples need a matching update.

The OpenGrep hint on Line 12 is a false positive. The require path is a fixed string built from __DIR__.
