Regular billing of your clients by server-server method

Scheme of API subscription
Forming a request to API for self-integration:
Example of using SDK:
	\"action\" : \"subscribe\",
    \"version\" : 3,
    \"public_key\" : \"${PUBLIC_KEY}\", 
    \"phone\" : \"380950000001\",
    \"amount\" : 1,
    \"currency\" : \"USD\",
    \"description\" : \"description text\",
    \"order_id\" : \"order_id_1\",
    \"subscribe\" : \"1\",
    \"subscribe_date_start\" : \"2016-03-31 00:00:00\",
    \"subscribe_periodicity\" : \"month\",
    \"card\" : \"4731195301524634\",
    \"card_exp_month\" : \"03\",
    \"card_exp_year\" : \"22\",
    \"card_cvv\" : \"111\"
