Examples#

How to initialize an object#

You can configure your bean, use application.yml, or instantiate an object via the constructor.

Via configuration:

@Configuration
public class GreenApiConf {

    @Bean
    public RestTemplate restTemplate() {
        return new RestTemplateBuilder().build();
    }

    @Bean
    public GreenApi greenApi(RestTemplate restTemplate) {
        return new GreenApi(
            restTemplate,
            "https://media.greenapi.com",
            "https://api.greenapi.com",
            "{{YOUR-ID}}",
            "{{YOUR-TOKEN}}");
    }
}

Via application.yml:

To use a ready-made bean that is created based on application.yml parameters, specify the parameters of your instance in the application.yml file as follows:

green-api:
   host: https://api.green-api.com
   hostMedia: https://media.green-api.com
   instanceId: {{yourInstance}}
   token: {{yourToken}}

Make sure you have a RestTemplate bean with your configuration, like this:

@Bean
public RestTemplate restTemplate(RestTemplateBuilder restTemplateBuilder){
    return restTemplateBuilder.build();
    }

And add "com.greenapi.client" to the base scanning packages using the @ComponentScan annotation:

@SpringBootApplication
@ComponentScan(basePackages = {"com.greenapi.client", "com.example"})
public class Application {

    public static void main(String[] args) {
        var context = SpringApplication.run(Application.class, args);
    }
}

Via constructor:

var restTemplate = new RestTemplateBuilder().build();

var greenApi1 = new GreenApi(
    restTemplate,
    "https://media.green-api.com",
    "https://api.green-api.com",
    {{instanceId1}},
    {{instanceToken1}});

var greenApi2 = new GreenApi(
    restTemplate,
    "https://media.greenapi.com",
    "https://api.greenapi.com",
    {{instanceId2}},
    {{instanceToken2}});

How to send a Poll#

Link to example: SendPollExample.java.

@Log4j2
public class SendPollExample {
    private void sendPollExample(GreenApi greenApi) {
        var options = new ArrayList<Option>();
        options.add(new Option("option 1"));
        options.add(new Option("option 2"));
        options.add(new Option("option 3"));

        var dto = OutgoingPoll.builder()
            .chatId("111111111111@c.us")
            .message("text message")
            .options(options)
            .multipleAnswers(false)
            .build();

        var response = greenApi.sending.sendPoll(dto);
        log.info(response);
    }
}
