Add Sandbox and Domain names; deprecate the Inbox and SendingDomain names - #88
Mailtrap now calls the Email Sandbox's testing inboxes sandboxes and sending domains domains, and the API reference documents only the new names. This PR gives the PHP SDK the new names and keeps every old one working as a deprecated alias. The official SDKs for other languages get the same rename and the same old → new mapping.
Requests still go to the same endpoints (/api/accounts/{id}/inboxes…, /api/accounts/{id}/sending_domains…). The API also serves /sandboxes and /domains paths, but some of their responses use different field names (sandbox_id instead of inbox_id), so switching paths is left to a future major version.
Changes
$sandboxClient->sandboxes($accountId) returns the new Api\Sandbox\Sandbox (getSandboxAttributes(), and $sandboxId parameters), and requests take DTO\Request\Sandbox
inboxes(), Api\Sandbox\Inbox, getInboxAttributes() and DTO\Request\Inbox still work; Inbox extends Sandbox and keeps its old parameter names, so calls with named arguments keep working
MailtrapClient::initSendingEmails() and the sandbox emails(), messages() and attachments() take sandboxId:, and the APIs they return have getSandboxId()
inboxId: and getInboxId() still work; passing sandboxId: and inboxId: with different values throws InvalidArgumentException
a missing sandbox id now throws InvalidArgumentException naming $sandboxId, instead of PHP's ArgumentCountError
The Symfony transport reads ?sandboxId= from MAILER_DSN, and the Laravel config key is sandboxId (MAILTRAP_SANDBOX_ID)
?inboxId=, an inboxId key in an already published config/services.php, and the MAILTRAP_INBOX_ID variable still work; different sandboxId and inboxId values throw InvalidArgumentException
the transport now prints as mailtrap+sdk://sandbox.api.mailtrap.io?sandboxId=…
Sending\Domain has getDomains(), createDomain(), updateDomain() and deleteDomain(); the *SendingDomain*() methods still work
Each old name emits a silenced E_USER_DEPRECATED notice the first time it is used in a process, saying what to use instead
this is the Symfony/Laravel convention: their error handlers log silenced deprecations and plain PHP ignores them; once per process keeps loops and queue workers from flooding the deprecation log
the old names will be removed in a future major release
The README gets a "Renamed APIs" table, and the docs and examples use only the new names: examples/testing/ moved to examples/sandbox/, examples/sending-domains/ to examples/domains/
Names that mirror an API field keep the old term: User::getList($inboxIds), PermissionInterface::TYPE_INBOX, the sendingDomainIds stats filters, and inbox_id in responses
How to test
You'll need an account API token, its account ID, a sandbox ID and a domain ID.
New names
Sandbox send — MailtrapClient::initSendingEmails(apiKey: …, isSandbox: true, sandboxId: <sandbox id>)->send($email) delivers to that sandbox, with no deprecation notice
Sandboxes — php examples/sandbox/sandboxes.php with MAILTRAP_ACCOUNT_ID, MAILTRAP_SANDBOX_ID and MAILTRAP_PROJECT_ID set lists, creates, reads, updates, cleans and deletes sandboxes as before
Messages and attachments — php examples/sandbox/messages.php and examples/sandbox/attachments.php with MAILTRAP_SANDBOX_ID work as the old examples/testing/ scripts did
Symfony — MAILER_DSN=mailtrap+sdk://<token>@sandbox.api.mailtrap.io?sandboxId=<sandbox id>, then php bin/console mailer:test you@example.com lands in the sandbox
Laravel — with no mailtrap-sdk key in config/services.php, MAIL_MAILER=mailtrap-sdk, MAILTRAP_HOST=sandbox.api.mailtrap.io and MAILTRAP_SANDBOX_ID=<sandbox id>, a sent mailable lands in the sandbox
Old names still work and are logged as deprecated (in Symfony's profiler or Laravel's deprecations log channel; plain PHP prints nothing)
initSendingEmails(…, isSandbox: true, inboxId: <sandbox id>) sends to the sandbox and logs that $inboxId is deprecated in favour of $sandboxId
->sandbox()->inboxes($accountId)->getInboxAttributes(<sandbox id>) returns the sandbox and logs that Inbox (inboxes()) and getInboxAttributes() are deprecated
->sending()->domains($accountId)->getSendingDomains() returns the domains and logs that getSendingDomains() is deprecated
Symfony — ?inboxId=<sandbox id> in MAILER_DSN still sends to the sandbox and logs that the inboxId option is deprecated
Laravel — a config/services.phpmailtrap-sdk entry with the old 'inboxId' => env('MAILTRAP_INBOX_ID') still sends to the sandbox; without that entry, MAILTRAP_INBOX_ID alone still works too; both log that inboxId / MAILTRAP_INBOX_ID is deprecated
Each notice is logged once per process, not on every call
Summary by CodeRabbit
New Features
Added sandbox management for listing, creating, updating, and deleting sandboxes, and managing their settings.
Added support for sandbox IDs in sandbox email, message, and attachment operations.
Added domain-named options for managing domains.
Compatibility
Existing inbox and sending-domain names remain supported and emit deprecation notices; use the sandbox and domain names for new integrations.
Existing inbox ID settings remain supported; sandbox ID settings are now documented as the preferred option.
Documentation
Updated examples and guides with sandbox and domain terminology and usage.
Decisions:
- Old names stay as aliases that call the same endpoints, so existing code keeps working until the next major release
- API paths are unchanged: the /sandboxes paths return sandbox_id instead of inbox_id, so moving to them belongs to a major version
- Deprecations are silenced E_USER_DEPRECATED notices, the Symfony/Laravel convention, emitted once per process so loops and queue workers don't flood the log
- The deprecated Inbox API keeps its old parameter names, because named arguments are part of the public API
- A missing sandbox id now throws InvalidArgumentException; __call no longer turns that into "undefined method"
- The Laravel config passes MAILTRAP_INBOX_ID through as inboxId, so the transport factory reports it as deprecated
- Passing sandboxId and inboxId with different values throws, as in the Ruby and Python SDKs
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The SDK adds sandbox-named management APIs and domain-named methods. Deprecated inbox and sending-domain paths remain available with deprecation notices. Integrations, examples, documentation, and tests use the new names and identifiers.
Changes: Sandbox API and compatibility
Layer / File(s)
Summary
Deprecation handling and renamed arguments src/Helper/Deprecation.php, src/MailtrapClient.php, src/Api/Sending/Domain.php, tests/Helper/*
A shared helper resolves renamed arguments and emits one deprecation notice per old name. Legacy inbox and sending-domain methods delegate to the new names.
Sandbox management and request contract src/DTO/Request/Sandbox.php, src/DTO/Request/Inbox.php, src/Api/Sandbox/Sandbox.php, src/Api/Sandbox/Inbox.php
The new Sandbox API manages sandbox records and actions. Inbox extends Sandbox and preserves deprecated compatibility behavior.
Sandbox clients and integrations src/Api/Sandbox/*, src/MailtrapSandboxClient.php, src/Bridge/Transport/*, src/Bridge/Laravel/*, src/Bridge/Symfony/README.md
Sandbox clients and transports use sandboxId. Deprecated inboxId inputs remain supported and conflicting identifiers are rejected.
Examples, documentation, and validation examples/*, README.md, UPGRADE-2.0.md, tests/Api/Sandbox/*, tests/MailtrapSandboxClientTest.php
Examples and guides use sandbox terminology and identifiers. Tests cover sandbox endpoints, compatibility paths, transport options, and deprecation behavior.
Domain API naming
Layer / File(s)
Summary
Domain methods and deprecated wrappers src/Api/Sending/Domain.php, tests/Api/Sending/DomainTest.php
The API adds getDomains, createDomain, updateDomain, and deleteDomain. Former sending-domain methods emit deprecation notices and delegate to the new methods.
Domain terminology in examples and documentation examples/domains/*, examples/marketing-stats/all.php, src/Api/Sending/*, src/DTO/Request/*, README.md
Descriptions and examples refer to domains instead of sending domains. Existing API fields and endpoint behavior remain unchanged.
A zero sandbox ID can select the old inbox instead of rejecting conflicting configuration. Correct the validation or accept this narrow risk before merging.

The 2.0 upgrade guide still linked examples/testing, which this branch
moved to examples/sandbox. The deprecated Domain and Inbox methods now
name themselves with __METHOD__, so the notice can't drift from the
method it is raised in.

Side note, not from this PR: the CI matrix lists PHP 8.0, but no PHP 8.0 job shows up in the checks, while composer.json still allows ^8.0. I checked by hand that named arguments forwarded through __call work on 8.0.
Decisions:
- The emails(), messages() and attachments() tags list both sandboxId and inboxId, so Psalm and PHPStan keep accepting existing inboxId: calls instead of reporting InvalidNamedArgument
- The Laravel README tells users with their own mailtrap-sdk entry in config/services.php to rename its key along with the variable, since that entry replaces the package default as a whole

Approving, with one nit inline.
Nit: the PR says examples use only the new names, but example comments still say “sending domain” (examples/batch/{transactional,bulk,bulk_template,transactional_template}.php, examples/email-campaigns/all.php:45). Replace with “domain” for consistency, or leave as is if help-centre wording still uses the old term.
Decisions:
- The transport silently preferred sandboxId on a conflict, while initSendingEmails() and the sandbox API constructors throw on the same mistake; now every entry point rejects it
- The transport keeps its own check rather than Deprecation::renamedArgument(), so the error names the DSN options and env vars users actually set

Decisions:
- Finish the rename in the examples; the help-centre link keeps its old slug, since the URL is not ours to change

- Line 78: Update the sandboxId/inboxId validation in
MailtrapSdkTransportFactory to distinguish an omitted sandboxId from the
explicitly supplied value '0'; reject the conflicting values '0' and '1234'
instead of falling back to inboxId. Add a test covering this case.

Decisions:
- empty() read '0' as unset, so sandboxId=0 with inboxId=1234 sent to 1234 instead of failing
- Only null and '' count as unset now, as initSendingEmails() rejects sandboxId: 0 with inboxId: 1234
- A zero ID on its own still means no sandbox ID, so the empty "sandboxId" error stays

Motivation
Mailtrap now calls the Email Sandbox's testing inboxes sandboxes and sending domains domains, and the API reference documents only the new names. This PR gives the PHP SDK the new names and keeps every old one working as a deprecated alias. The official SDKs for other languages get the same rename and the same old → new mapping.
Requests still go to the same endpoints (
/api/accounts/{id}/inboxes…,/api/accounts/{id}/sending_domains…). The API also serves/sandboxesand/domainspaths, but some of their responses use different field names (sandbox_idinstead ofinbox_id), so switching paths is left to a future major version.Changes
$sandboxClient->sandboxes($accountId)returns the newApi\Sandbox\Sandbox(getSandboxAttributes(), and$sandboxIdparameters), and requests takeDTO\Request\Sandboxinboxes(),Api\Sandbox\Inbox,getInboxAttributes()andDTO\Request\Inboxstill work;InboxextendsSandboxand keeps its old parameter names, so calls with named arguments keep workingMailtrapClient::initSendingEmails()and the sandboxemails(),messages()andattachments()takesandboxId:, and the APIs they return havegetSandboxId()inboxId:andgetInboxId()still work; passingsandboxId:andinboxId:with different values throwsInvalidArgumentExceptionInvalidArgumentExceptionnaming$sandboxId, instead of PHP'sArgumentCountErrorThe Symfony transport reads

You'll need an account API token, its account ID, a sandbox ID and a domain ID.
