  <artifactId>paypal-server-sdk</artifactId>
  <version>2.3.0</version>
</dependency>

You can also view the package at: https://central.sonatype.com/artifact/com.paypal.sdk/paypal-server-sdk/2.3.0

Initialize the API Client

Note: Documentation for the client can be found here.

The following parameters are configurable for the API Client:

Parameter	Type	Description
environment	Environment	The API environment. Default: Environment.SANDBOX
httpClientConfig	Consumer<HttpClientConfiguration.Builder>	Set up Http Client Configuration instance.
loggingConfig	Consumer<ApiLoggingConfiguration.Builder>	Set up Logging Configuration instance.
clientCredentialsAuth	ClientCredentialsAuth	The Credentials Setter for OAuth 2 Client Credentials Grant

The API client can be initialized as follows:

import com.paypal.sdk.Environment;
import com.paypal.sdk.PaypalServerSdkClient;
import com.paypal.sdk.authentication.ClientCredentialsAuthModel;
import com.paypal.sdk.exceptions.ApiException;
import com.paypal.sdk.http.response.ApiResponse;
import com.paypal.sdk.models.OAuthToken;
import java.io.IOException;
import org.slf4j.event.Level;

public class Program {
    public static void main(String[] args) {
        PaypalServerSdkClient client = new PaypalServerSdkClient.Builder()
            .loggingConfig(builder -> builder
                    .level(Level.DEBUG)
                    .requestConfig(logConfigBuilder -> logConfigBuilder.body(true))
                    .responseConfig(logConfigBuilder -> logConfigBuilder.headers(true)))
            .httpClientConfig(configBuilder -> configBuilder
                    .timeout(0))
            .clientCredentialsAuth(new ClientCredentialsAuthModel.Builder(
                    "OAuthClientId",
                    "OAuthClientSecret"
                )
                .build())
            .environment(Environment.SANDBOX)
