payment4j

An abstraction layer over various payment services like Paypal, AuthorizeNet, Stripe… payment4j allows you to create a shopping site without the heavy part of dealing with a custom API.

Usage

Simple purchase

CreditCard creditCard = new CreditCard().setNumber("4007000000027")
		.setType(CreditCardType.VISA).setFirstName("John")
		.setLastName("Doe").setMonth(12).setYear(2015)
		.setVerificationValue("000");
AuthorizeNetGateway
		.build(true, “authorizenet.apiLoginId”,“authorizenet.transactionKey”).
			transaction
				.purchase(Money.of(CurrencyUnit.EUR, 10), creditCard);

Recurring

CreditCard creditCard = new CreditCard().setNumber("4007000000027")
		.setType(CreditCardType.VISA).setFirstName("John")
		.setLastName("Doe").setMonth(12).setYear(2015)
		.setVerificationValue("000");
Schedule schedule = new Schedule();
schedule.setEach(ScheduleUnit.MONTH);
schedule.setTotalOccurences(3);
AuthorizeNetGateway
	.build(true, “authorizenet.apiLoginId”,“authorizenet.transactionKey”)

			.recurring(Money.of(CurrencyUnit.EUR, 10), creditCard, schedule);

Build the project

mvn clean install -DskipTests

(Yeah, all tests are not fixed yet…)

Testing

Since we need some accounts for testing and we can’t expose them in public, you have to create a properties file in src/main/test named “accounts.properties”. A template is already present in the folder, just remane it “accouts.properties” and fill the blank inside.
