Anda dapat menggunakan mysql-udf-http dan kemudian membuat pemicu seperti ini:
delimiter $$
CREATE TRIGGER upd_check BEFORE UPDATE ON account
FOR EACH ROW
BEGIN
IF NEW.amount > 0 THEN
set @json = select json_object(account_id,amount)
select http_post('http://restservice.example.com/account/post',@json);
END IF;
END;$$
delimiter;
