This endpoint allows you to delete a transactional template.
Each user can create up to 300 different transactional templates. Transactional templates are specific to accounts and subusers. Templates created on a parent account will not be accessible from the subuser accounts.
Transactional templates are templates created specifically for transactional email and are not to be confused with Marketing Campaigns templates. For more information about transactional templates, please see our User Guide.
