From WhatsApp perspective we support images, text, video, audio, contact, location, sticker, document messages types

To send campaign of template messages this cronjob has to be setup.

How to listen for quick reply actions from templates you send?

Each quick reply button send from lhc get's payload constructed as.

$item->template.'-quick_reply_'.$indexButton, => quick_reply-quick_reply_0

This is needed because we don't have chat upfront and can't set payload upfront.

So just listen for Custom text matching with that keyword. This sample is provided in bot sample

I have bot for default department, but I want chat go directly to pending state if I send a template?

You have few options

One account multiple page installation workflow

This workflow is usefull if you are planning to use more than one page per facebook account.

One app multiple servers installation

This scenario is usefull in case you have multiple clients and each client has it's own server or address. You can have one master instance which will act as Master and will forward all incoming request from facebook to correct URL of child server.

To activate that option you have to edit extension/fbmessenger/settings/settings.ini.php and set options similar to below

'standalone' => array (
        'enabled' => true,
        'disable_manual_whatsapp' => false, 
        'secret_hash' => 'random_string_to_out',
        'address' => 'https://mater.example.com' // Master instance address
    ),

In facebook Valid OAuth Redirect URIs has to be changed to E.g

https://mater.example.com/site_admin/fbmessenger/fbcallbackstandalone

Messenger -> Settings Webhooks Callback URL has to be set to

https://mater.example.com/fbmessenger/callbackstandalone

Then Submit to facebook to validate your app

Finally Make your app public.

How it works

Once visitor writes a message in facebook page. You will receive a chat with visitor.

How to debug

in extension/fbmessenger/settings/settings.ini.php change setting to 'enable_debug' => true if you have verified site. Check cache/default.log for more detailed error.
