possible error when adding routes

[KevinJoseph]

Hi, I'm starting the following:

const { createBot } = require('whatsapp-cloud-api');
const axios = require('axios');
const express = require('express');

const app = express();

const from = process.env.WHATSAPP_PHONE_NUMBER_ID;
const token = process.env.WHATSAPP_TOKEN;
const webhookVerifyToken = process.env.VERIFY_TOKEN;

// Create a bot that can send messages
const bot = createBot(from, token);
(async function() {
await bot.startExpressServer({
webhookVerifyToken: process.env.VERIFY_TOKEN,
port: process.env.PORT || 2040,
webhookPath: /webhook,
});
})();

app.get('/hello', (req, res) => {
res.send('Hello World!')
})
but when consulting the /hello route it gives me 404 as a result, is there an error with the route handler? thank you

You need to supply the app value to the function for creating the server, ie:

await bot.startExpressServer({

  // add this:
  app, 

  webhookVerifyToken: process.env.VERIFY_TOKEN,
  port: process.env.PORT || 2040,
  webhookPath: '/webhook', 
});

Also, nit, perhaps you can move the async definition to the top, i.e:

(async function() { 
  const app = express();

  // ... 

  app.get('/hello', (req, res) => {
    res.send('Hello World!')
  })
})()

Thank you very much, is it possible to integrate socket io too?

Most welcome.

Unsure why you would need socket.io since you won't be able to integrate it with the Whatsapp app. Unless if you mean integration with your own service (e.g. your own frontend), then yes, you can definitely do it.

[KevinJoseph]

That's right, I want to integrate it with my own interface

I am developing it this way but the app stops.
const from = process.env.WHATSAPP_PHONE_NUMBER_ID;
const token = process.env.WHATSAPP_TOKEN;
const webhookVerifyToken = process.env.VERIFY_TOKEN;
const bot = createBot(from, token);

(async function() {
const app = express();

// ...

app.get('/hello', (req, res) => {
res.send('Hello World!')
})

await bot.startExpressServer({

// add this:
app, 

webhookVerifyToken: process.env.VERIFY_TOKEN,
port: process.env.PORT || 2040,
webhookPath: '/webhook', 

});
})()

If I comment these lines of the file, startExpressServer.js executes me correctly

Hi @KevinJoseph, Did you manage to fix this?

Can you clarify what you mean by If I comment these lines of the file; which lines specifically?

Closing this due to insufficient info. @KevinJoseph, feel free to reopen :)
