Motivation

The Mailtrap API is getting a DELETE /api/organizations/{organization_id}/sub_accounts/{sub_account_id} endpoint. This exposes it in the Ruby SDK next to the existing list and create.

Changes

• SubAccountsAPI#delete(sub_account_id) – sends the delete request and returns nil on the 204 response; a 404 (unknown or already deleted id) raises Mailtrap::Error like the other delete methods
• the doc comment records the endpoint semantics: organization admin permissions required, deletion is permanent and removes all sub account data, deleting the last sub account deletes the organization, repeated call returns 404, rate limit 10 requests per minute per organization
• specs for the success and not-found cases; the success case creates its own sub account and deletes it, so re-recording never deletes an existing one; the VCR cassettes are hand-crafted against the OpenAPI spec
• example and readme: added delete to examples/sub_accounts_api.rb and the missing Sub Accounts API link under "General"

How to test

• with an organization API token: Mailtrap::SubAccountsAPI.new(org_id, client).delete(sub_account_id) for an existing sub account – returns nil, the sub account is gone from list
• call delete again with the same id – raises Mailtrap::Error with Not Found
• delete with a sub account id that belongs to another organization – raises Mailtrap::Error with Not Found
• delete with a token that only has sub account management permissions – raises Mailtrap::Error with the 403 response
• delete with an invalid API key – raises Mailtrap::Error with the 401 response
• ruby -c examples/sub_accounts_api.rb – Syntax OK; the readme "General" list renders the new Sub Accounts API link

Companion PRs

• document the delete organization sub account endpoint mailtrap-openapi#56 – spec
• add sub account deletion mailtrap-nodejs#159 – nodejs SDK

• add sub-account deletion to the CLI mailtrap-cli#15 – CLI
• add delete-sub-account tool mailtrap-mcp#144 – MCP server

Caveat: the VCR cassettes under spec/fixtures/vcr_cassettes/Mailtrap_SubAccountsAPI/_delete/ are hand-crafted. To re-record them, delete that folder first (VCR only records cassettes that don't exist yet), then run bin/record-vcr --org spec/mailtrap/sub_accounts_api_spec.rb -e '#delete'.

Summary by CodeRabbit

• New Features

  • Added the ability to permanently delete a sub-account by ID, subject to organization-admin permissions.
  • Successful deletions return no content. Requests for non-existent sub-accounts return a not-found error.
  • Deleting a sub-account affects its associated data and may be restricted when it is the organization’s last sub-account.

• Documentation

  • Added a sub-account deletion example to the supported functionality documentation, demonstrating the successful deletion result.

Walkthrough

SubAccountsAPI now provides a delete method for sub-account removal. The change adds success and not-found coverage, an example, and a README entry.

Changes: Sub-account deletion

Layer / File(s)	Summary
Add and document deletion lib/mailtrap/sub_accounts_api.rb, examples/sub_accounts_api.rb, README.md	Adds SubAccountsAPI#delete(sub_account_id), which calls base_delete. The example shows a deletion that returns nil, and the README lists the example under supported functionality.
Test deletion responses spec/mailtrap/sub_accounts_api_spec.rb, spec/fixtures/vcr_cassettes/Mailtrap_SubAccountsAPI/...	Tests that successful deletion returns nil and that deleting a nonexistent sub-account raises Mailtrap::Error with “Not Found” details. The VCR cassettes record the corresponding 204 and 404 responses.
