Webhook problem

[Lorenzo Stflorant]

Hello, i'm trying to use Webhook method to handle the incoming message.
But i get a problem: i get the update object always shows null value

There are some code below:

TelegramBot bot = new TelegramBot(botToken);
SetWebhook request = new SetWebhook().url(url + "/api/telegram/webhook");
BaseResponse response = bot.execute(request);
log.info("webhook response: {}", response.description());

It will get log:

webhook response: Webhook was set

And the getWebhookInfo shows:

{
  "ok": true,
  "result": {
    "url": "https://xx.xx/api/telegram/webhook",
    "has_custom_certificate": false,
    "pending_update_count": 0,
    "max_connections": 40,
    "ip_address": "xx.xx.xx.xx",
    "allowed_updates": [
      "message",
      "callback_query"
    ],
  "last_synchronization_error_date": 1714206571
  }
}

I write a Controller to get income upadte object:

@RestController
@RequestMapping("/api")
@RequiredArgsConstructor
public class TelegramBotController {

    private final TelegramService telegramService;

    @PostMapping("/telegram/webhook")
    public boolean telegramWebhook(@RequestBody Update update) {
        return telegramService.handleWebhook(update);
    }
}

TelegramService:

public boolean handleWebhook(Update update) {
        log.info("handleWebhook: {}", update);
        if (ObjectUtil.isEmpty(update.message())) {
            return false;
        }
        Message message = update.message();
        if (ObjectUtil.isNotEmpty(message.entities())) {
            if (message.text().startsWith("/start")) {
                handleStart(message);
            }
        }
        return true;
    }

Here log always shows update object:

handleWebhook: Update{update_id=null, message=null, edited_message=null, channel_post=null, edited_channel_post=null, business_connection=null, business_message=null, edited_business_message=null, deleted_business_messages=null, inline_query=null, chosen_inline_result=null, callback_query=null, shipping_query=null, pre_checkout_query=null, poll=null, poll_answer=null, my_chat_member=null, chat_member=null, chat_join_request=null, message_reaction=null, message_reaction_count=null, chat_boost=null, removed_chat_boost=null}

what's the problem in my code

[Lorenzo Stflorant]

Problem solved.

for security, set secretToken here

SetWebhook request = new SetWebhook().url(url + "/api/telegram/webhook").secretToken("MetePayBot");

Controller

@PostMapping("/telegram/webhook")
public boolean telegramWebhook(@RequestHeader("X-Telegram-Bot-Api-Secret-Token") String token, @RequestBody String requestBody) {
    return telegramService.handleWebhook(token, requestBody);
}

Service

public boolean handleWebhook(String token, Update update) {
        log.debug("token: {}", token);
        if (ObjectUtil.notEqual(token, "Your Security Token")) {
            return false;
        }
        log.debug("requestBody: {}", requestBody);
        Update update = BotUtils.parseUpdate(requestBody);
        log.debug("handleWebhook: {}", update);
        if (ObjectUtil.isEmpty(update.message())) {
            return false;
        }
        Message message = update.message();
        if (ObjectUtil.isNotEmpty(message.entities())) {
            if (message.text().startsWith("/start")) {
                handleStart(message);
            }
        }
        return true;
    }
