  page.handle_webhook(request.get_data(as_text=True))
  return "ok"

@page.handle_message
def message_handler(event):
  """:type event: fbmq.Event"""
  sender_id = event.sender_id
  message = event.message_text

event.quick_reply dict : quick reply dict that is received. more detail

event.quick_reply_payload str : `event.quick_reply.get('payload')

page = fbmq.Page(PAGE_ACCESS_TOKEN, after_send=after_send)

@app.route('/webhook', methods=['POST'])
def webhook():
  page.handle_webhook(request.get_data(as_text=True),
                      message=message_handler)
  return "ok"

def message_handler(event):
  """:type event: fbmq.Event"""
  sender_id = event.sender_id
  message = event.message_text
  
  page.send(sender_id, "thank you! your message is '%s'" % message)

def after_send(payload, response):

Send a message

how to send a message from facebook page to user

Basic

Import
from fbmq import Attachment, Template, QuickReply, Page
Text
page.send(recipient_id, "hello world!")
Image

jpg, png, gif support

page.send(recipient_id, Attachment.Image(image_url))
Audio
page.send(recipient_id, Attachment.Audio(audio_url))
Video
page.send(recipient_id, Attachment.Video(video_url))
File
page.send(recipient_id, Attachment.File(file_url))
quick reply
quick_replies = [
  QuickReply(title="Action", payload="PICK_ACTION"),
  QuickReply(title="Comedy", payload="PICK_COMEDY")
]

# you can use a dict instead of a QuickReply class
#
# quick_replies = [{'title': 'Action', 'payload': 'PICK_ACTION'},
#                {'title': 'Comedy', 'payload': 'PICK_COMEDY'}}


page.send(recipient_id, 
          "What's your favorite movie genre?",
          quick_replies=quick_replies,
          metadata="DEVELOPER_DEFINED_METADATA")
quick reply callback

you can define easily a quick reply callback method.

@page.callback(['PICK_ACTION', 'PICK_COMEDY'])
def callback_picked_genre(payload, event):
  print(payload, event)
  
# Also supported regex, it works corretly
# @page.callback(['PICK_(.+)'])

if you want to handle only quick_reply callback without button postback

@page.callback(['PICK_ACTION', 'PICK_COMEDY'], types=['QUICK_REPLY'])
typing on/off
page.typing_on(recipient_id)
page.typing_off(recipient_id)

Templates

Template : Button
buttons = [
  Attachment.ButtonWeb("Open Web URL", "https://www.oculus.com/en-us/rift/"),
  Attachment.ButtonPostBack("trigger Postback", "DEVELOPED_DEFINED_PAYLOAD"),
  Attachment.ButtonPhoneNumber("Call Phone Number", "+16505551234")
]

# you can use a dict instead of a Button class
#
# buttons = [{'type': 'web_url', 'title': 'Open Web URL', 'value': 'https://www.oculus.com/en-us/rift/'},
#          {'type': 'postback', 'title': 'trigger Postback', 'value': 'DEVELOPED_DEFINED_PAYLOAD'},
#          {'type': 'phone_number', 'title': 'Call Phone Number', 'value': '+16505551234'}]

page.send(recipient_id, Template.Buttons("hello", buttons))
button callback

you can define easily a button postback method (it works only postback type buttons).

@page.callback(['DEVELOPED_DEFINED_PAYLOAD'])
def callback_clicked_button(payload, event):
  print(payload, event)
  
# Also supported regex, it works corretly
# @page.callback(['DEVELOPED_DEFINE(.+)'])

if you want to handle only button's postback without quick_reply callback

@page.callback(['DEVELOPED_DEFINED_PAYLOAD'], types=['POSTBACK'])
