Motivation

The SDKs now name the Email Sandbox's testing inboxes sandboxes and sending domains domains, matching the paths this reference already documents. The old names (client.testing.inboxes, testInboxId, InboxesAPI, sendingDomains, ...) still work, but they are deprecated and emit warnings. This PR switches the API reference samples to the new names, so readers copy code that doesn't warn.

The new names ship in Ruby 2.20.0, Python 3.1.0, PHP 3.18.0, Node.js 6.2.0, Java 1.11.0, .NET 3.10.0 and Go 0.6.0 (mailtrap/mailtrap-ruby#139, mailtrap/mailtrap-python#92, mailtrap/mailtrap-php#88, mailtrap/mailtrap-nodejs#180, mailtrap/mailtrap-java#91, mailtrap/mailtrap-dotnet#266, mailtrap/mailtrap-go#39).

Changes

• Sandbox samples (projects, sandboxes, messages, attachments) use the sandbox entry points in Node.js, PHP, Python, Ruby, .NET and Java

  • client.testing.inboxes → client.sandbox.sandboxes, client.testing_api → client.sandbox_api, Mailtrap::InboxesAPI → Mailtrap::SandboxesAPI, ->inboxes() → ->sandboxes(), .Inboxes()/.Inbox(id) → .Sandboxes()/.Sandbox(id), testingApi().inboxes().getInboxes() → sandboxApi().sandboxes().getSandboxes()
  • Variables and placeholders follow: sandboxId, sandbox_id, MAILTRAP_SANDBOX_ID
  • Java and .NET have renamed only their entry points so far, so CreateInboxRequest, UpdateInboxRequest, Mailtrap.Inboxes.Requests and Mailtrap.TestingMessages.Requests keep their names until each SDK's next major release

• Sandbox send and batch send samples pass the sandbox ID under its new name: sandboxId (Node.js, PHP, Java, .NET options) or sandbox_id (Python, Ruby). .NET calls .Sandbox(id)/.BatchSandbox(id) instead of .Test(id)/.BatchTest(id)

• Domain samples use the domain entry points

  • Node.js client.domains, Python client.domains_api.domains, Ruby Mailtrap::DomainsAPI, PHP getDomains()/createDomain()/deleteDomain(), .NET .Domains()/.Domain(id), Java getDomains()/getDomain()/deleteDomain()/sendDomainSetupInstructions(), Go client.Domains
  • The Java and .NET request types (CreateSendingDomainRequest, Mailtrap.SendingDomains) keep their names, for the same reason

• Some calls on the renamed lines didn't match the SDK, and are now fixed: Node.js projects.getById (was projects.get), getHtmlMessage(sandboxId, messageId) (had an extra account ID), attachments.getList(sandboxId, messageId) (arguments were swapped), and the Java CreateInboxRequest import package

• Unchanged: inbound samples, Terraform, cURL, and names that mirror API fields (inbox_id on messages, sending_domain_ids filters, inbox_ids on account accesses)

How to test

• Sandbox pages: on Projects, Sandboxes, Messages and Attachments, the Node.js, PHP, Python, Ruby, .NET and Java tabs use client.sandbox, sandbox_api, SandboxesAPI, sandboxes(), .Sandboxes()/.Sandbox(id) and sandboxApi(). None of them shows testing, inboxes() or inboxId
• Sandbox sending: "Send email" and "Batch send email" pass sandboxId / sandbox_id / SandboxId, and .NET uses .Sandbox(...) / .BatchSandbox(...)
• Domains pages: create, list, get, update, delete, send setup instructions and company info use client.domains, domains_api.domains, DomainsAPI, getDomains(), .Domains() and Go client.Domains
• Released SDKs: copy one sample per language into a project on the SDK version listed above. It runs without a deprecation warning
• Regression: Inbound pages still use the inbound inbox names (InboundInboxesAPI), and the Terraform tabs are unchanged

Walkthrough

The OpenAPI code samples now use Domains APIs for email-domain operations and sandbox APIs and identifiers for sandbox management and email operations. The documented HTTP endpoints and request and response specifications remain unchanged.

Changes: Email domain samples

Layer / File(s)	Summary
Domain operations and company information specs/email-sending.openapi.yml	Domain creation, listing, retrieval, deletion, updates, setup instructions, and company-info examples now use Domains APIs and domain-specific method names across the shown SDKs.

Sandbox samples

Layer / File(s)	Summary
Project and sandbox management specs/sandbox.openapi.yml	Project and sandbox examples use sandbox clients and operations instead of testing or inbox APIs.
Sandbox controls specs/sandbox.openapi.yml	Cleaning, mark-as-read, credential reset, and email-address examples use sandbox clients and identifiers.
Sandbox messages and attachments specs/sandbox.openapi.yml	Message and attachment examples use sandbox APIs and sandbox IDs instead of testing or inbox APIs and IDs.
Single and batch sending specs/sandbox-sending.openapi.yml	Single-send and batch-send examples use sandbox IDs; the .NET and Java examples also select sandbox email clients.

Merge Risk: Low · previous review 02e07

The Ruby example should read its API key from the environment before merging. The remaining risk is limited to that sample.

read the API key from the MAILTRAP_API_KEY environment variable instead of
embedding a placeholder key in source code; preserve the existing sandbox and
