If you are using Spring, you can use the RestTemplate Spring REST client to make a call to an external API from Java.

Example:

 HttpHeaders headers = new HttpHeaders();
 headers.setContentType(MediaType.APPLICATION_JSON);
 HttpEntity<String> request = new HttpEntity<>(someDto, headers)
 restTemplate.postForEntity(postUrl, request, String.class);
