Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to The existing templates accessor changes endpoint, pagination, response envelopes, and write shapes. Existing integrations therefore require migration despite the stated opt-in intent. A stable replacement and major-version upgrade guidance reduce the risk, but release compatibility remains unresolved. No credential escalation or cross-account access vulnerability was established.

…resource
- client.templates now serves the paginated /api/templates surface: getList
takes { token, per_page } and resolves { data, pagination }, get/create/update
resolve { data }, bodies are flat. Pagination is reused from types/api/common.
- The /api/email_templates resource is removed rather than kept behind a
deprecated name: 5.0 is the release where a removal can land, and callers
touching client.templates for the new shapes would have to edit every call
site anyway.
- Breaking for callers of client.templates, so this needs a major release;
the README gains an "Upgrading to 5.0" note.

…mplates - Restore client.templates to the stable /api/email_templates endpoints, so this ships in 4.x with no breaking change. /api/templates is still experimental, and the 5.0 switch would have broken mailtrap-mcp on its next bump. - Move the /api/templates resource to the opt-in client.paginatedTemplates, marked experimental. - Type body_html and body_text as string | null, as the API returns them. - Accept a null token and per_page in getList, so pagination.next_token can be passed back as is. - Add examples/templates/paginated.ts, which follows next_token.

…t.emailTemplates - client.templates calls the paginated /api/templates endpoints, so the agreed name needs no rename once the endpoints leave experimental. - The 4.x resource stays unchanged as client.emailTemplates on the stable /api/email_templates endpoints. Users who want the stable API rename one property and keep their code. - Say in the JSDoc and README that /api/templates shapes may change in a minor release while the endpoints are experimental. - examples/templates/everything.ts shows the paginated flow; email-templates.ts keeps the 4.x flow.

Motivation
Mailtrap now serves a conventions-compliant templates API at
/api/templates(and/api/accounts/{account_id}/templates): every response is wrapped in adataenvelope, the list is paginated withtoken/per_page, and write bodies are flat. The existing/api/email_templatessurface keeps its published shape and stays the stable way to manage templates.This is a major release (5.0.0) that gives
client.templatesthe new endpoints now, so the name never has to move again: when/api/templatesleaves experimental, nothing changes forclient.templatesusers. The 4.x resource is kept, unchanged, asclient.emailTemplates, so nobody is forced onto the experimental endpoints. To keep the 4.x behavior, a user renamesclient.templatestoclient.emailTemplates.client.emailTemplatescan be deprecated once/api/templatesis generally available.While the endpoints are experimental,
client.templatesshapes may change in a minor release. The JSDoc and the README say so, so a shape change before GA does not force another major.Changes
client.templates(TemplatesApi/TemplatesBaseAPI) targets/api/accounts/{id}/templates:getList({ token, per_page })resolves{ data, pagination }, get/create/update resolve{ data }, delete resolves on204; bodies are flatbody_htmlandbody_textarestring | nullon the response, because the API returnsnullfor a body the template has none oftokenandper_pageacceptnulland skip it, sopagination.next_tokencan be passed back as isPaginationis reused fromtypes/api/common.tsclient.emailTemplates(EmailTemplatesApi/EmailTemplatesBaseAPI, types intypes/api/email-templates.ts): the 4.x resource, moved and renamed with no behavior changeexamples/templates/everything.tsfollowsnext_tokenacross pages; the 4.x flow moved toexamples/templates/email-templates.tsDependents
