Every bot has to be connected to a Facebook page to work on Facebook Messenger.
When you first log onto Facebook and set your Facebook pages to the Bot Platform make sure to click
Open Edit Settings - Choose the Pages you want to use with the Bot Platform or tick Select All.
You have to have Admin status in the Page Roles to create a bot.
If you do not have this level of permission, the Page will not show in this list.
Now when you go back to The Bot Platform you will be able to connect your bot to one of these pages. See the Test Bot Page below.
Click 'Connect' and you bot is created and waiting for your to build messages
Happy bot building!
