Consuming SAP Process Orchestration RESTful Web Services with Basic Authorization Using Java and Spring Framework

Category:Programming,SAP,SAP PI/PO


In modern enterprise application development, integrating with external services is a common requirement. SAP Process Orchestration (SAP PO) offers a robust platform for orchestrating business processes and integrating systems, including exposing RESTful web services. In this article, we will explore how to consume a RESTful web service exposed in SAP PO using Java and the Spring Framework, with basic authorization.


Before we begin, let’s clarify some assumptions:

  1. You have a basic understanding of Java and the Spring Framework.
  2. You have access to an SAP Process Orchestration instance with a RESTful web service exposed.
  3. The SAP Process Orchestration RESTful web service requires basic authorization.


To consume the SAP Process Orchestration RESTful web service, follow these steps:

  1. Set Up Your Project: Create a new Java project and add the required dependencies for the Spring Framework and Spring Boot. You can use Maven or Gradle for dependency management.
  2. Create a RestTemplate Bean: In your Spring configuration class, create a bean for RestTemplate. This bean will be used to make HTTP requests to the SAP PO RESTful web

@Configuration public class AppConfig { @Bean public RestTemplate restTemplate() { return new RestTemplate(); } }

Consume the RESTful Web Service: In your main class or service class, use the RestTemplate bean to consume the SAP PO RESTful web service. Replace with the actual URL of your SAP PO RESTful web service, and replace your-username and your-password with your SAP PO credentials.


public class Main {

public static void main(String[] args) {

String url = "";

String username = "your-username";

String password = "your-password";

RestTemplate restTemplate = new RestTemplate();

HttpHeaders headers = new HttpHeaders();

headers.setBasicAuth(username, password);

HttpEntity<String> entity = new HttpEntity<>(headers);

try {

ResponseEntity<String> response =, HttpMethod.GET,

entity, String.class);

if (response.getStatusCode() == HttpStatus.OK) {


} else {

System.out.println("Failed to call the API. Status code: " +



} catch (Exception e) {

System.out.println("An error occurred: " + e.getMessage());




  1. Run Your Application: Run your Java application. If everything is set up correctly, the application should make a GET request to the SAP PO RESTful web service and print the response body to the console.


In this article, we have demonstrated how to consume a RESTful web service exposed in SAP Process Orchestration using Java and the Spring Framework, with basic authorization. By following the steps outlined in this article, you can integrate your Java applications with SAP PO and leverage its capabilities for business process orchestration and system integration.
