Facebook Messenger webhook gets triggered by button click but not from text message

Question

Weird behavior.

I've setup a bot for the new Facebook Messenger and it is working. But now, it just triggers the webhook post method when I click at the buttons that the bot sent. If I send a simple text message through fb messenger it doesn't trigger (If I send it manually using postman for example it works).

So, when the post receives this, it works:

{  
   "object":"page",
   "entry":[  
      {  
         "id":"526506374188753",
         "time":1476539505993,
         "messaging":[  
            {  
               "recipient":{  
                  "id":"123123123123"
               },
               "timestamp":1476539505993,
               "sender":{  
                  "id":"123123123123"
               },
               "postback":{  
                  "payload":"someparameterId"
               }
            }
         ]
      }
   ]
}

If fb messenger sends this, it doesn't reach my post webhook method.

{  
   "object":"page",
   "entry":[  
      {  
         "id":"526506374188753",
         "time":1475591255490,
         "messaging":[  
            {  
               "sender":{  
                  "id":"123123123123"
               },
               "recipient":{  
                  "id":"123123123123"
               },
               "timestamp":1475591255378,
               "message":{  
                  "mid":"mid.1475591255319:16b11b18bd2174bf78",
                  "seq":141,
                  "text":"hi bot!"
               }
            }
         ]
      }
   ]
}

Any idea?

This can be fixed by subscribing to the page. ScreenShot

When you subscribe to the page, you will receive all the event from that page which you have checked - message_deliveries, messages, messaging_optins, messaging_postbacks,etc. to your webhook url.
