Requirements

• Admin access to a Facebook Page
• A Facebook App
• Node.js

Setup

To build your own bot from scratch (or with a little help), try the Messenger Platform Quick Start Tutorial.

Otherwise, to run this bot, configure your app on Facebook Developers with the following permissions:

• messages
• messaging_postbacks
• messaging_referrals
• messaging_account_linking

After associating your page with the webhook, run

npm install

to install required Node packages. Start the server running

node server.js

Fill the backend_config.js file with your Page Access Token, and a VERIFICATION_TOKEN with a non-guessable string.

For initial tests or development, you can install and use Local Tunnel. With your node server up, run

lt --port 65172

Use the domain provided by Local Tunnel to replace DOMAIN in backend_config.js and in product/payment_test/frontend_config.js, and restart your node server. Setup your webhook with:

<lt_domain> + /webhook

Input the same VERIFICATION_TOKEN from your backend_config.js.

Ex.:

To enable Account Kit login, whitelist the domain and redirect url ending with akit_success in your app dashboard (https://developers.facebook.com/apps/<APP_ID>/account-kit/settings/).

Optional

In order to use a product from your Dynamic Ads product catalog, provide an User Access Token with business_management permission from an advertiser/admin of a product catalog. In backend_config.js, fill USER_ACCESS_TOKEN and PRODUCT_ID.
