Build the JAR

To build the JAR you can run mvn install.

Usage

Setup

You can use the API with a static defined Mollie API key Client or a dynamic key DynamicClient.

Static

Client client = new ClientBuilder()
					.withApiKey("XXX")
					.build();

Dynamic

DynamicClient client = new DynamicClientBuilder()
							.build();

Configuration

Both clients make use of the Jackson ObjectMapper and the Apache HTTP HttpClient. These can be respectively configured using withMapper and withClient.

Note 1: The library uses jackson-datatype-jdk8. To make sure that the ObjectMapper can serialise java.util.Optional the library registers the module in the ObjectMapper.

Note 2: The ObjectMapper has the FAIL_ON_UNKNOWN_PROPERTIES property disabled by default to make the deserialisation more forgiving (#25). If you inject your own ObjectMapper, please consider disabling this property: When Mollie adds a property and you do not disable this, and they do this now and then, deserialisation will fail with an exception.

API Calls

The API is separated into different concepts:

• Methods: Used to read the available payment methods.
• Issuers: Used to read the available issuers per payment method.
• Payments: Used to create read and delete payments
• Refunds: Used to create read and delete refunds on payments
• Status: Used to verify the validity of the used API key

All concepts can be retrieved from the client using the following format client.<concept>().

For example you can create a payment as follows:

Client client = new ClientBuilder()
					.withApiKey(""XXX")
					.build();

client.payments().create(new CreatePayment(...));
