To create the app, head over to and click on My Apps → Add New App.
Go onto the dashboard for the app, and under Products, find the Messenger section and click Set Up. Scroll down to Token Generation and click on the link to create a new page for your app.
Create your page and select it in the dropdown menu for the Token Generation. The shown Page Access Token is the page-access-token needed later on.
Locate the App Secret in the app dashboard under Settings → Basic. This will be your secret.
Use the collected secret and page-access-token in your credentials.yml, and add a field called verify containing a string of your choice. Start Rasa run with the --credentials credentials.yml option.
