Before publishing your bot, you'll need to:

Please note that bot cannot be deployed on the same Facebook page. In case the bot has been connected to a Facebook page before, then you must Unassign to change from your old bot to the bot you want to connect to that Facebook page.

Customize bot behaviours

BotStar does provide some options to customize the behaviour of your chatbot on Messenger. Please note that Facebook provides very limited ability to change any visual settings for bot on Messenger.


Here bot operator will see Whitelisted Domain. This is a list of third-party domains that are accessible in the Messenger webview. Learn more about Messenger Webview here. You can also publish your chatbot for the whitelisted domains (websites). It's recommended to keep as a whitelisted domain for webview components such as calendar, payment to function.

Contact us at if you are interested in developing webview for your chatbot.

Please note that this is different to the Website Domains if you also publish your bot to website.


Disable Message Composer field so the only way your user can interact with your bot is via buttons and quick replies, webviews. End users won't be able to type their response. We do not recommend this behaviour unless your chatbot expect any input from users and provide navigations via buttons or quick reply only.

Here is the result after enabling Disable Message Composer
