$ npm install

Alternatively, you can use Yarn:

$ yarn install

3. Set up .env file

cp .sample.env .env

Edit the .env file to add all the values for your app and page. Note that APP_URL will be the external URL from step 1.

4. Run your app locally

node app.js

You should now be able to access the application in your browser at http://localhost:3000

Confirm that you canalso access it at the external URL from step 1.

5. Configure your webhook subcription and set the Messenger profile

Use the VERIFY_TOKEN that you created in .env file and call the /profile endpoint in your browser or via cURL:

http://localhost:3000/profile?mode=all&verify_token=verify-tokenl

This will configure your webhook.

6. Test that your app setup is successful
