Amazing tutorial, you not only shows us commands and lines of code, you actually teach and I find it amazing

[@joaopedrogirelli1257]

Underrated tutorial!

[@arnavghosh4242]

This tutorial is really useful, since you can just modify the code and host it on vercel or render

[@mcqueenyaqueen7061]

In my case its always error in ngrok
bad gateway 502 and got error
node:internal/process/promises:289
AxiosError [AggregateError]
Can you help me

[@othekaka]

OMG, that's a best tutorial that I've seen. You've explain everything about the process, thanks for your video. Just one thing, If I use "node-telegram-bot-api" will be not necessary use the ngork, right?

[@lets-build-together]

Hey thank you! I didn’t use that api, but, if you are using webhook, you need it, since telegram only supports https.
github.com/yagop/node-telegram-bot-api/blob/master/doc/usage.md#webhooks

[@ogs102]

please can have one for nextjs

[@Dungboreview]

Hey bro, what happens when we not using webhook ?

[@lets-build-together]

Then you can use polling, where you can check telegram every x seconds(say 5 seconds) , then every 5 seconds you can check with telegram servers that any new message is there

[@bhai431]

*Wich app is this: **1:20** please make Detail Video not able to understand in this sir. Pleasssereeeeerrrr*

[@lets-build-together]

Hey hi, yes i will try to make as detailed as possible, next time. The app I am using is VsCode, but you can use any code editor

[@amaechichisom787]

How do i deploy this on prod with ngrok

[@lets-build-together]

You don’t need to ngrok to deploy to prod. If you follow later videos we deployed to production

[@user-er9wc2jt2m]

"Sir, will this ngrok make my Telegram bot appear 24/7?"

[@okonkwo.ify18]

Explain more so I help you

[@khaisarbegum2134]

​​@@okonkwo.ify18
Deploy the server publicly so it can be accessed(using ngrok)
Can you please help me on this

[@dixankay9986]

Please can we get he source code? At least for the setup part

[@lets-build-together]

Hey hi, all the code I showed in the video. If you still need the source code, please email me, I will share it with you.

[@user-bc1xp2of2x]

where we can mail you, say the id or direct guthub link

Keep doing this great work bro!
Also need a javascript course in your language.
Your explanation is top notch😊

[@lets-build-together]

Thank you, will consider making a course in future

[@wessel_g45]

Hi,
It was all working perfectly fine before, but now I am getting the 405 'not allowed' results with ngrok. Not sure how to get it working again.
Steps I am taking
- running `ngrok http 4040` in terminal
- copying the url to postman and adding it the api call, resulting in 'webhook was set' in postman
- terminal gives back: POST/ 405 method not allowed
Tried this steps multiple times. What could be wrong?
Great tutorial btw, thanks

[@kpokpefavourogheneruese5527]

Good morning bro, how did you fix this?

[@JethiyaChampakGada]

This tutorial is unnecessarily complex

[@CryLight-]

I do not mean to sound rude; do you have a better one, as I’m a beginner and would like to develop a telegram bot

[@JethiyaChampakGada]

@@CryLight- I'm also learning to develop but his code is bit complex, logic and functionality is simple and good but the syntax is the complex

[@qiyamelislam]

hey hi , i got an error says that messageObj.text is undefined

[@lordesca4364]

Did you get any solution regarding this, i am getting the same error.

[@nikkifacts07]

use if condition if you got messageObj then it go ahead
@@lordesca4364

[@lets-build-together]

Hey hi, as @nikkifacts07 said, have a if condition check. Also check if you server is reacting to any other requests apart of telegram

[@lordesca4364]

@@lets-build-together it is better with long polling instead of webhooks

[@sindyquispe2419]

how did you solve it?
