i have no money in my debit card but transaction is done

[nabeelirbab]

In my app when I try new SDK and test app in sandbox mode I got this response:
{
client = {
environment = sandbox;
"paypal_sdk_version" = "2.0.2";
platform = iOS;
"product_name" = "PayPal iOS SDK";
};
response = {
"create_time" = "2017-06-15T10:19:02Z";
id = "PAY-6C9862538L110700WKNGQPFQ";
intent = sale;
state = approved;
};
"response_type" = payment;
}

That means my transaction done successfully. But i have no money in my account .Also when we had no funds and tried our VIsa, we had no error saying: Insuffecient funds

There may be certain amounts to throw different errors. This way is common in Braintree Gateway, I suppose the system for unsuccessful transaction will be similar for PayPal.

In short: in test mode does not matter if you have money in wallet unless you send specific amount which should mean failed transaction.
