Motivation

The organization sub-accounts API can list and create sub-accounts but not delete them. The new DELETE /api/organizations/{organization_id}/sub_accounts/{sub_account_id} endpoint needs an SDK method.

Changes

• SubAccount::deleteSubAccount(int $subAccountId) – sends the delete request and returns the 204 response
• unit tests for the success, forbidden and not-found cases
• examples/sub-accounts/all.php gets a delete block that deletes the sub-account the example just created; the sub-accounts example is now linked from both READMEs

How to test

Use a token with organization admin permissions and an organization that has at least two sub-accounts (deleting the last one deletes the organization).

• $subAccounts->deleteSubAccount($id) with an existing sub-account id – returns a response with status 204; the sub-account disappears from getSubAccounts()
• call deleteSubAccount($id) again with the same id – throws HttpClientException with a 404 not-found message
• call it with a sub-account id from another organization – throws HttpClientException with a 404 not-found message
• call it with a token that only has sub-account management permissions – throws HttpClientException with a 403 message
• call it with an invalid token – throws HttpClientException with a 401 message
• run MAILTRAP_API_KEY=... MAILTRAP_ORGANIZATION_ID=... php -d variables_order=EGPCS examples/sub-accounts/all.php – prints the list, the created sub-account and 204; the created sub-account is gone from getSubAccounts() afterwards
• README.md and examples/README.md render the new sub-accounts row next to the API tokens row

Walkthrough

The SubAccount API now supports deleting a sub-account. Tests cover successful deletion and HTTP 403 and 404 responses. The example calls the deletion method, and the README files list the sub-account operations.

Changes: Sub-account deletion

Layer / File(s)	Summary
Deletion API and validation src/Api/General/SubAccount.php, tests/Api/General/SubAccountTest.php	deleteSubAccount sends a DELETE request for the specified sub-account and processes the response. Tests cover HTTP 204, 403, and 404 responses.
Example and documentation updates examples/sub-accounts/all.php, README.md, examples/README.md	The example saves the created sub-account ID, calls deleteSubAccount, and prints the response status. Both README files list the sub-account operations.

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Feature

Suggested reviewers: igordobryn, piobeny

Merge Risk: Moderate · up to 3109d

The example could delete an organization if the created sub-account is its last. Verify that case or require confirmation before merging.

Make the deletion example opt-in.

When this runnable example executes, $subAccounts->deleteSubAccount(12347) can permanently delete that sub-account and, if it is the organization’s last sub-account, the organization. Require explicit environment values before calling deleteSubAccount().

Proposed safeguard

-    $subAccountId = 12347;
+    $subAccountId = (int) ($_ENV['MAILTRAP_SUB_ACCOUNT_ID'] ?? 0);
+    if ($subAccountId <= 0 || ($_ENV['CONFIRM_SUB_ACCOUNT_DELETION'] ?? '') !== 'yes') {
+        throw new RuntimeException('Set MAILTRAP_SUB_ACCOUNT_ID and CONFIRM_SUB_ACCOUNT_DELETION=yes to run deletion.');
+    }

Confirm that the equivalent Mailtrap app examples remain accurate.

Make the deletion example opt-in.

The sample deletes hard-coded sub-account 12347 without confirmation. It can delete an unrelated sub-account or the organization if it is the last sub-account. Read the ID and an explicit confirmation from environment variables before calling deleteSubAccount().

Please also confirm that the equivalent Mailtrap app examples remain accurate.
