Invoke the getWebhookInfo API method and find out what is wrong with your web hook. Below is what I get when I did not have a public CA certificate

Code:

curl 'https://api.telegram.org/bot<MY_API_TOKEN>/getWebhookInfo'

{"ok":true,"result":{"url":"https://my.callback.host/","has_custom_certificate":false,"pending_update_count":32,"last_error_date":1486903822,"last_error_message":"SSL error {336134278, error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed}","max_connections":40}}

I have to thank that you have this enquiry, so I get to play with the Telegram Bot API.

I have used Cloudflare to provide a public CA SSL certificate for Telegram client.

This is what I did to configure Telegram bot webhook

Code:

curl -F 'url=https://host.domain/johnlittle/index.php' -F 'max_connections=1' -F 'allowed_updates=' 'https://api.telegram.org/bot34******31:***********/setWebhook'

This is what my PHP code looks like

Code:

# cat index.php
<?php
$body = file_get_contents('php://input');
error_log($body);
?>

When the bot receive any messages, for example, a "testing 123" message

This is shown in the server error logs

Code:

2017/02/12 22:01:13 [error] 6699#6699: *4337 FastCGI sent in stderr: "PHP message: {"update_id":926****412,
"message":{"message_id":70,"from":{"id":21****509,"first_name":"*****","last_name":"*****","username":"******"},"chat":{"id":21*****09,"first_name":"*****","last_name":"*****","username":"*****","type":"private"},"date":1486908071,"text":"testing 123"}}" while reading response header from upstream, client: 127.0.0.1, server: _, request: "POST /johnlittle/index.php HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", host: "*******"

I have masked out confidential information with the structure retained.

Update: If you would like to use a self-signed certificate, this would be how you setup the webhook

Code:

curl -F 'url=https://callback.domain/johnlittle/index.php' -F 'max_connections=1' -F 'allowed_updates=' -F 'certificate=@issuer.crt' 'https://api.telegram.org/bot34*****31:********************/setWebhook'

You will need to upload the public certificate used to sign your server certificate. If it is self-signed certificate, it will be the same as your server certificate. If you are using your own self-created CA, you will need to upload your self-created CA certificate.

Thanks!
after reading your post i have finally got a direction.
Now i know that it is not my ssl that have problem, but my code that having some issues.

Code:

$website = "https://api.telegram.org/bot".$botToken;

$update = file_get_contents("php://input");

//print_r($update);

$updateArray = json_decode($update,TRUE);
//error_log($updateArray);
$chatID= $updateArray["result"][0]["message"]["chat"]["id"];


//$text = $updateArray["result"][0]["message"]["text"];

file_get_contents($website."/sendmessage?chat_id=".$chatID."&text=HELLO!");

If i sub the $chatID with my telegram id, i am able to receive reply.
But when when i use $chatID it gives and error.

Code:

PHP Notice:  Undefined index: result in /var/www/html/telebot2.php on line 11

Code:

PHP Warning:  file_get_contents(https://api.telegram.org/bot######/sendmessage?chat_id=&text=HELLO!): failed to open stream: HTTP request failed! HTTP/1.1 400 Bad Request\r\n in /var/www/html/telebot2.php on line 16

When you use print_r to print out your JSON array, did you not notice your mistake ? Are you sure there is a "result" index in the JSON array that you have decoded ?

Here is a sample

Code:

# cat index.php
<?php
$body = file_get_contents('php://input');
$o = json_decode($body, true);
error_log(print_r($o, true));
$id = $o['message']['chat']['id'];
$txt = $o['message']['text'];
$dt = date("D, d M Y H:i:s");
system("curl -F 'parse_mode=Markdown' -F 'chat_id=$id' -F 'text=You ask me *\"$txt\"* on *$dt*' 'https://api.telegram.org/bot3*****1:AAF******_YzQ/sendMessage'");
?>

Update: There is a security problem with the code above. Who wanna take a stab at it?

You sure you don't want to take a closer stab at it ?

Really ??? Okay say you give up!

Code Injection. In this case, Shell code injection

Code:

'.$(ls).'

Solved!!!!

Your method of parsing json is correct.

I parsed according to get updates
Which is different!!

I guess will use this thread to update my progress on making my telegram bot

My parsing of JSON is not different from yours.

We are using the same php json decoding library. The difference is how we extract information from the associative array. You have to take note on how you are extracting information from a data structure

Update since the last post after help from davidktw

I have tried to implement a simple chatbot idea

My bot helps to get some price quote for SGX stocks,
also there is an alert function able to notify me when the price have reached as shown in second picture.

Current problem:
some stock quotes such as D05 is not working,
it shows fail to open stream, because the string converts & to & which makes it an invalid link in telegram.

Future idea:
Update me when there is new SGX news.

Also is there any idea for telegram bot so i can try out?

wah u write from scratch? i went for the "fast & easy" solution which is to clone an existing bot written in python and modify it slightly for my use.

Paging for all pro programmers. I need some help.

I am trying to use to 'Switch to Inline buttons' function which i read from
https://core.telegram.org/bots/2-0-intro#switch-to-inline-buttons

but i can't seem to get it to work.

The closest i ever got was below:

This is using the code

Code:

https://api.telegram.org/bot[API KEY]?chat_id=[CHAT_ID]&text=Hello&reply_markup={%22keyboard%22:[[%22Yes%22,%22No%22],[%22Maybe%22],[%221%22,%222%22,%223%22]],%20%22one_time_keyboard%22:true}

But i want the inline keyboard to be in the message screen and not the keyboard.

Is there any one have experience in this?
Im not using any library so i trying to find a way to do it just by file_get_content or curl
