What Is a Facebook Messenger Chatbot?

Types of Messenger Chatbots

Rule-Based Chatbots: Operate using pre-defined scripts and decision trees to respond to user queries.
AI-Powered Chatbots: Utilize machine learning and NLP to offer dynamic, context-aware responses that improve over time.

What Are the Business Benefits of Building a Messenger Chatbot?

Step 3: Create a Welcome Message to Kick Off the Conversation

First, users open the “Welcome” block for editing.

Drop the Messenger Text card into the dashboard.
Write a friendly greeting, e.g., Welcome, Mr. Chris, to Smax AI. How can I assist you today?

To personalize the message as in the example above, you need to input functions starting with square brackets “[..]” or curly braces “{…}”.

Users can create button content based on their goals. Smax AI suggests the following basic buttons: View Products, Call Hotline, Visit Website.

Step 4: Create a Product Listing Message for Customers to Browse Products

In the current Messenger Text card of the “Welcome” block.

Select Add button.
Name the button “View Products” > In the Block section, choose Create New Block > Name the new block “View Products”

Then, users open the “View Products” block for editing.

Step 5: Create a Request Info and Order Confirmation Message

Users open the “Request Customer Info” block for editing.

Drop the Messenger Text card into the dashboard.
Enter the customer info request message, e.g., “If you’re ready to order Plain black babytee, which is $10, just need a little info from you to get that sorted.”
To include confirmation of Product Name and Price in the message, enter the character { and select the attributes “product_name” and “product_price”.

Then, to create automatic questions to collect data:

Drop the Messenger User Input card.
Enter the message.
Create attributes corresponding to each piece of customer information.

Examples:

Question about customer’s full name → Attribute: full_name
Question about customer’s phone number → Attribute: phone_number

Next, to confirm customer’s order info:

Drop the Messenger Text card
Enter the message content
For each piece of information, the user will select the corresponding attribute
Create a Confirm button > Create an Order Confirmation block.

Note: When the customer confirms that the details are correct, the ‘Confirm’ button directs them to the ‘Order Confirmation’ block. If there are any mistakes in the customer’s information, the ‘Edit’ button automatically restarts the chatbot at the ‘Request Customer Info’ block.

This is a complete order confirmation message.

Choose Messenger Welcome.
Turn on the “Get Started” button and Link it to the “Welcome” block.
