Check Receipt with shared secret
For checking receipt , recommend to use only for server side. I am not recommend to use from client side directly check it. However, sometime we want to use only on client side for some reason. Use with your own risk.
Please check Apple guide .

}];
Check Receipt without shared secret
For checking receipt , recommend to use only for server side. I am not recommend to use from client side directly check it. However, sometime we want to use only on client side for some reason. Use with your own risk.
