Let us see how we can get started with a bot.
Dragging and Dropping
From the doc menu, drag the Trigger component and drop it on the editor and connect it to either the Start Bot Flow or New Postback component. Once you’re done with making the bot, Save the bot flow and start with the messenger.
To add data to the Trigger component, click twice on the body of the Trigger component. It will open a sidebar on your right. Now provide some keywords there, separated by a comma. In our case, we’re providing a single keyword product. Now press the OK button.

The bot will start working if a user types products on the messenger of the Facebook page as you set it via the Trigger component. That’s it. Trigger Component
