Enterprise Java: Integrating WhatsApp API with Spring Boot

Modernizing Enterprise Java

Large enterprises, banks, and logistics companies heavily rely on Java and Spring Boot. Upgrading user communication from legacy SMS gateways to WhatsApp doesn't require overhauling your monolith. 5MinutesAPI provides a standardized REST interface easily consumable via RestTemplate or WebClient.

Implementation with WebClient

For modern, non-blocking Spring Boot applications, WebClient is the optimal choice to hit our high-speed endpoints.

import org.springframework.web.reactive.function.client.WebClient;

public class WhatsAppService {
private final WebClient webClient;

public WhatsAppService() {
    this.webClient = WebClient.builder()
        .baseUrl("https://api.5minutesapi.com/v1")
        .defaultHeader("Authorization", "Bearer YOUR_API_KEY")
        .build();
}

public void sendAlert(String phone, String template) {
    // Build JSON payload logic here
    webClient.post()
        .uri("/send-message")
        .bodyValue(payload)
        .retrieve()
        .bodyToMono(String.class)
        .subscribe(); // Non-blocking async execution
}


}
