Map<String, Object> chargeParams = new HashMap<>();
Map<String, Object> address = new HashMap<>();
address.put("line1", creditCardForm.getAddress().toLowerCase());
address.put("country", creditCardForm.getCountry().toLowerCase());
Map<String, Object> shipping = new HashMap<>();
shipping.put("name", email);
shipping.put("address", address);
chargeParams.put("amount", amount * 100);
chargeParams.put("currency", token.getCard().getCurrency().toLowerCase());
chargeParams.put("description", description);
chargeParams.put("source", token.getId());
chargeParams.put("shipping", shipping);
charge = Charge.create(chargeParams);

In the above code we create map for required parameter for charge and charge class have a method .create() .so given amount is deducted from you credit card account which is given in amount parameter .

Conclusion :

Stripe payment gateway is easy to use for credit and debit charges from the card and it is also easy to integrate with the application using api key and secrete key. To test entire flow we did not need to real card stripe provide mock card for testing purpose.
