Hello @sradityaa, if you're using Spring Boot, you should implement a controller to receive notifications sent by WhatsApp servers. I don't have a code example, but you can take a look at this link

You can use this SDK to deserialize an event. Here's an example.

I hope this helps. When I have more examples, I'll post them here.

hey @sradityaa , check the SpringBoot example below.

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/whatsapp")
@SpringBootApplication
public class WhatsappWebhook {

	private static final Logger log = LoggerFactory.getLogger(WhatsappWebhook.class);

	public static void main(String[] args) {
		SpringApplication.run(WhatsappWebhook.class, args);
	}

	@GetMapping(path = "/webhook")
	public String get(@RequestParam(value = "hub.challenge") String challenge,
			@RequestParam(value = "hub.verify_token") String verifyToken) {
		if (log.isDebugEnabled()) {
			log.debug("Challenge received: {}", challenge);
		}

		if ("myWebhookToken".equals(verifyToken)) {
			log.info("Facebook Verify Token checked succesfully");

			return challenge;
		} else {
			log.info("Invalid Facebook Verify Token");

			return "error";
		}
	}

	@PostMapping(path = "/webhook", consumes = "application/json")
	public void post(@RequestBody String payload) {
		log.debug("Event received: \n {}", payload);
	}

}

Don't forget to setup your webhook with the correct token (myWebhookToken as in the example) and the url https://mydomain.com/whatsapp/webhook

I hope this helps
