Review Question and Answers You can Submit:


During the Permission review process for Page messaging, you will need to answer a few questions and provide access to your WordPress dashboard. You can use parts of the text below to answer the questions as appropriate.

** We need the Page Messaging feature so that the ChatBot can reply to customer queries using DialogFlow integration of WPBot and also other WPBot features like Simple Text Responses, FAQ, Product display etc.

Once the Setup is complete and all the FB App permissions are working the following features will be available to the WordPress site admin:

Respond to customer queries on messenger and Facebook page through the WPBot using DialogFlow and Simple Text Responses
Connect the ChatBot with multiple FB pages.
Auto comments reply to your Facebook pages from WordPress dashboard
Comment replies with various conditions from WordPress dashboard
Comment reply from DialogFlow
Auto comments reply campaign setup from WordPress dashboard
Manage FB page Subscribers
Send Broadcast Messages according to FB policy from WordPress dashboard
One-click enable/disable bot for FB pages

The ChatBot responses can be managed from the WordPess backend. WordPress admin can also integrate with DialogFlow to create the ChatBot responses.


The Messenger Platform’s Broadcast API allows you to broadcast a message to everyone that currently has an open conversation with your Page. The broadcast message is displayed on the Page inbox only when a user replies in a thread.


“pages_messaging” permission is needed to send broadcast.

Rate Limits

Rate limits are in place to prevent malicious behavior and poor user experiences.

The per day rate limit is equal to 200 * the number of people the business can message via Messenger.

For pages with large audiences, we recommend a send rate of 250 requests per second.
