Discard your override and go back to the default template: your header, body, footer, signature and subject are cleared. Your on/off, logo and delivery settings stay, and so do template_mode and a saved full-HTML version (custom_html).

Prerequisites: a bearer token, the account's id (company_id) and the email type from List email types.

Authentication: Partner or Account token. company_id must be inside your own account tree (a Partner token reaches any account under the partner, an Account token only its own); otherwise 422. The account's partner must have the email templates section turned on; otherwise 403. Types managed centrally by the platform return 403.

Rate limit: none.
