Steps To Integrate Stripe Payment Gateway In Java

Step 1: First of all you have to add a stripe dependency in your pom.xml file

<dependency>
<groupId>com.stripe</groupId>
<artifactId>stripe-java</artifactId>
<version>21.9.0</version>
</dependency>

Step 2: After that mention the currency and secret key of stripe in your application.properties file. For getting a secret key you have to create an account or already have an account on stripe is mandatory

stripe.currency=usd
stripe.secretKey=sk_test_54naj..........

Step 3: Now create a function to add a customer on stripe

import com.stripe.model.Customer;
import java.util.*;

Map<String, Object> customerParameter = new HashMap<String, Object>();
customerParameter.put("name", "abc");
customerParameter.put("email", "[email protected]");

Map<String, Object> address = new HashMap<>();
address.put("line1", addressLine1);
address.put("line2", addressLine2);
address.put("city", city);
address.put("state", state);
address.put("postal_code", zipcode);
address.put("country", country);

customerParameter.put("address", address);

For adding a customer on stripe you should use Stripe customer class function i.e. Customer.create()

Customer customer = Customer.create(customerParameter);

For getting a customer from stripe you should use retrive() function of stripe customer class

Customer cus = Customer.retrieve(customerId);

Step 4: After adding a customer now you should add a card on stripe for a customer

Map<String, Object> retrieveParams =new HashMap<>();
List<String> expandList = new ArrayList<>();
expandList.add("sources");
retrieveParams.put("expand", expandList);
Customer customer = Customer.retrieve(customerId,retrieveParams,null);

Map<String, Object> params = new HashMap<>();
params.put("source", "tok_visa");

Card card = (Card) customer.getSources().create(params);

step 5: After adding customer and card, now you can processing a payment

Map<String, Object> params = new HashMap<>();
params.put("amount", amount);
params.put("confirm", true);
params.put("off_session", true);
params.put("customer", customer != null ? customer.getId() : null);
params.put("currency", currency);
params.put("description",description);

PaymentIntent paymentIntent = PaymentIntent.create(params);

Note: if the paymentIntent.getStatus() is equal to "succeeded" that means your payment is successful, otherwise your payment has failed.
