This example project creates a Facebook Messenger bot, mirroring the quickstart located in Messenger Platform docs.
It's an echo bot that responds to a user's message by repeating their message back to them. It also sends a generic template when a message with "generic" text is received. This project is not dependent on any external libraries and can easily be extended.
To get started you need to:
-
Set up your Facebook app on Facebook
-
Configure your Facebook App
The
Callback URL
you set when configuring your app on Facebook is your Glitch project's publish URL with '/webhook' appended. The publish URL is what loads when you click 'Show' and has the format 'https://project-name.glitch.me', so for this example we used 'https://messenger-bot.glitch.me/webhook' for the Callback URL.The
Verify Token
is a string you make up - it's just used to make sure it is your Facebook app that your server is interacting with. -
Copy your app credentials into the
.env
file
