Save for single send API in the new Site Version


I saw that you changed site represent, and just now I can not save email for single-send API because I can not find where it is. Using hapikey I always get "Content is not valid for use with single send API. Requires subcategory 'single_send_api'". Please, explain what goes wrong.


Hi @BohdanDubrovnyi,

Can you give me some more details on this? A link to the template in question would be helpful.
