  1. I have a problem, I tried to make my own, I even tested your application, but anyway it seems that it goes into a loop, the chatbot keeps flooding, it seems to have something to do with the webhooks, in addition to those webhook configurations, something was missing that you forgot to suggest?

    1. Hello, I am getting a 404 error and facebook is not validating my callback link. You have any idea why the app.js file is not picking up the indexroutes

    2. Hi @Rebot
      Im reaching out to see if you managed to get around the “chatbot flooding messages to users” part?
      I created mine too and from time to time the chatbot seems to send duplicate responses to users?

  2. A brilliant blog and an even better Node.js library. I can highly recommend the library to ANY developer wanting to integrate with the WhatsApp Cloud API. Well done to all contributors!

  3. Thanks for the example it works but I get a cyclic repetition of the POST.
    POST: Someone is pinging me!
    POST: Someone is pinging me!
    POST: Someone is pinging me!
    POST: Someone is pinging me!

    How can I avoid it?. Thank you.

    1. Hello @Jairo and @Rebot.

      Change the below block of code from:

      const WhatsappCloudAPI = require(‘whatsappcloudapi_wrapper’);
      const Whatsapp = new WhatsappCloudAPI({
      accessToken: process.env.Meta_WA_accessToken,
      senderPhoneNumberId: process.env.Meta_WA_SenderPhoneNumberId,
      WABA_ID: process.env.Meta_WA_wabaId,
      });

      to this:

      const WhatsappCloudAPI = require(‘whatsappcloudapi_wrapper’);
      const Whatsapp = new WhatsappCloudAPI({
      accessToken: process.env.Meta_WA_accessToken,
      senderPhoneNumberId: process.env.Meta_WA_SenderPhoneNumberId,
      WABA_ID: process.env.Meta_WA_wabaId,
      graphAPIVersion:’ v14.0′
      });

  4. Olá.

    Estoura um erro no console quando realizo um teste no webhook.

    POST: Someone is pinging me!
    {
    error: Error: WABA_ID is not valid. Hint: the message is not intended for this Whatsapp Business Account.

  5. Hi.I was following this tutorial and was working for a month it was working fine but when now I am trying to configure webhook i am getting an “The callback URL or verify token couldn’t be validated. Please verify the provided information or try again later” error.I tried to create with all new accounts but still i am getting this error.Can you please suggest what should I do?

    1. Olá. Passei por problema parecido.
      Tente a tag — region au no ngrok.
      Na documentação você pode especificar a região do seu servidor usando essa tag. Ficando:
      ngrok http 8000 –region au
      Na documentação tem as regiões disponíveis.

  6. Hie. Thanks for this great article. I have been following through the steps outlines but when i try to configure webhooks url on facebook it gives this error.
    “The URL couldn’t be validated. Response does not match challenge, expected value=”481656951″, received=”\u003C!DOCTYPE html>\n\u003Ch…“

  8. Dear @daggieblanqx,

    I wanted to express my gratitude for the outstanding work you have done on this article. Your clear and concise step-by-step instructions have made it easy for anyone to understand and implement. As a result, I was able to successfully create an ecommerce WhatsApp bot using your guidance. Your hard work has paid off and I want to give you my sincerest compliments. Keep up the excellent work.

    Best regards,

    Luke
