fbmessenger 3.1.2

Facebook Messenger
==================

|PyPI| |Build Status| |Coverage Status| |PyPI|

A python library to communicate with the Facebook Messenger API's

Installation
------------

Install from pip

::

pip install fbmessenger

Facebook app setup
------------------

- `Create a page <https://www.facebook.com/pages/create/>`__ for your
app, if you don't already have one
- `Create an
app <https://developers.facebook.com/quickstarts/?platform=web>`__
- Add the Messenger product
- Select the Page to generate a page token

Example usage with Flask
------------------------

First you need to create a verify token, this can be any string e.g.

::

'my_verify_token'

Messenger class
~~~~~~~~~~~~~~~

We need to extend the ``BaseMessenger`` abstract class and implement
methods for each of the following subscription fields.

- ``message``
- ``delivery``
- ``read``
- ``optin``
- ``postback``
- ``account_linking``

.. code:: python

from fbmessenger import BaseMessenger


class Messenger(BaseMessenger):
def __init__(self, page_access_token):
self.page_access_token = page_access_token
super(Messenger, self).__init__(self.page_access_token)

def message(self, message):
self.send({'text': 'Received: {0}'.format(message['message']['text'])})

def delivery(self, message):
pass

def read(self, message):
pass

def account_linking(self, message):
pass

def postback(self, message):
pass

def optin(self, message):
pass

Create a route for the callback url
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This can be used to process any messages received and also to verify
your app

.. code:: python

import os
from flask import Flask, request

app = Flask(__name__)
app.debug = True

messenger = Messenger(os.environ.get('FB_VERIFY_TOKEN'), os.environ.get('FB_PAGE_TOKEN'))

@app.route('/webhook', methods=['GET', 'POST'])
def webhook():
if request.method == 'GET':
if (request.args.get('hub.verify_token') == os.environ.get('FB_VERIFY_TOKEN')):
return request.args.get('hub.challenge')
raise ValueError('FB_VERIFY_TOKEN does not match.')
elif request.method == 'POST':
messenger.handle(request.get_json(force=True))
return ''


if __name__ == "__main__":
app.run(host='0.0.0.0')

Elements
--------

Import the elements (or just the ones you need)

::

from fbmessenger import elements

messenger.send({'text': msg})

messenger.send(elem.to_dict())

Web button
~~~~~~~~~~

.. code:: python

btn = elements.Button(title='Web button', url='http://example.com')
messenger.send(btn.to_dict())

Payload button
~~~~~~~~~~~~~~

To use these buttons you must have the ``message_deliveries``
subscription enabled

.. code:: python

btn = elements.Button(title='Postback button', payload='payload')
messenger.send(btn.to_dict())

Code Contributions
------------------

When contributing code, you'll want to follow this checklist:

1. Fork the repository on GitHub.
2. Run the tests to confirm they all pass on your system. If they don't,
you'll need to investigate why they fail. If you're unable to
diagnose this yourself, raise it as a bug report by following the
guidelines in this document: Bug Reports.
3. Write tests that demonstrate your bug or feature. Ensure that they
fail.
4. Make your change.
5. Run the entire test suite again, confirming that all tests pass
including the ones you just added.
6. Send a GitHub Pull Request to the main repository's master branch. 7.
GitHub Pull Requests are the expected method of code collaboration on
this project.
