Creating a Drag & Drop Chatbot Using Flow Builder

The Pabbly Chatflow Flow Builder enables you to create static chatbots effortlessly using an intuitive drag-and-drop interface. This guide will walk you through the process of building a chatbot in just 10 minutes.

Trigger Events

The Trigger Events are defined to initiate actions or flows based on user interaction. You can choose different types of triggers to start your flow, such as keywords, regex patterns, or predefined events.

• Keyword/Regex Match
  • Trigger the flow when a user's message matches any defined keyword or regex pattern.
• User Starts Conversation
  • Trigger occurs when a user initiates a new conversation.
• Template Selected
  • Trigger the flow when a user replies via a quick reply button on a sent template.
• WhatsApp Template Delivered
  • Triggered when a WhatsApp message template is successfully delivered to a contact.
• Contact Added
  • Trigger when a new contact is created manually or by lead.
• Contact Added to Contact List
  • Trigger when a contact is added to one of the selected contact lists.
• Custom Field Updated
  • Trigger when a custom field is added or updated for a contact.
• Tag Assigned
  • Trigger the flow when a tag is assigned to a contact during an update.
• Payment Capture
  • Triggers when a customer’s payment is successfully captured.
• Order Received
  • Triggers when a customer adds a product to the cart.
  • If you select this as the trigger event, make sure to set the order type as WhatsApp Cart in the WhatsApp Pay node.

Skip Trigger Matching

The Skip Trigger Matching toggle controls whether a flow should execute when an AI Assistant is already assigned to a conversation.

How It Works

When Enabled

• If an AI Assistant is already assigned to the conversation:
  → The flow is skipped
• The AI Assistant continues responding normally
• No keyword or regex-based flow execution occurs

---

When Disabled (Default Behavior)

• Flow executes normally based on trigger conditions
• If user input matches:
  • Defined keywords, OR
  • Regex patterns
    → Flow will run
• This happens even if an AI Assistant is active

---

When to Use

1. AI-First Conversations

Use this when AI Assistant is the primary responder, and flows should not interrupt.

---

2. Ongoing Conversations

If a user is already engaged with AI, avoid restarting flows on every message.

8.WhatsApp Pay Message:

How WhatsApp Payments Work with Flows

Step 1: Log in and Open the Flow Creation Page

1. Log in to your Pabbly Chatflow account using your registered credentials.
2. From the left-hand navigation menu, click on Flows.
3. You will be redirected to the Flow List page. Here, locate the Add Flow button in the top-right corner and click on it.
4. This will take you to the Create Flow page, where you can begin setting up your new flow.

Prerequisite: Enable WhatsApp Pay in Flows

1. To create a flow using WhatsApp Payment, you must first configure at least one Payment Gateway and create at least one Order Message (of any type) and both should be Active.
2. Once your Payment Gateway is successfully configured and an Order Message is created, a new message called “WhatsApp Pay” becomes available inside Flows.
3. Before completing this setup, the WhatsApp Pay message remains disabled in the Flow builder.
4. As soon as your payment configuration is complete and an Order Message is available, the WhatsApp Pay message becomes enabled and ready to use.

• WhatsApp Pay message before configure Payment Gateway

  

  

  • WhatsApp Pay message after configure Payment Gateway

  

  

  1. From this point forward, you can place the WhatsApp Pay message anywhere inside your Flow, depending on how you want customers to receive order messages and payment links.

  WhatsApp Pay works with three different Order Message Types:

  1. WhatsApp Cart
  2. Custom Product
  3. Catalog Product

  Each of these types determines how the order is created, how products appear to the customer, and how payment links behave.

  1. Using WhatsApp Pay with the "WhatsApp Cart" Order Message Type

  When using WhatsApp Pay message with the WhatsApp Cart Order message type, the order creation process begins directly inside the customer’s WhatsApp application.

  1. The customer selects products from your Meta Catalog, adds them to the WhatsApp Cart, and places an order.
  2. As soon as this happens, the Order Received trigger fires inside your Flow. This trigger is specifically designed to capture WhatsApp Cart orders and start automation based on them.
  3. To begin, open the Flow Builder and set Order Received as the Trigger event in flow start. From there, drag the WhatsApp Pay message into the Flow and connect it.

  

  Select WhatsApp Cart and Configure Order Message

  1. In the WhatsApp Pay message choose WhatsApp Cart as the Order Message Type.
  2. The Order Message dropdown will automatically filter to display only WhatsApp Cart–based Order Messages.
  3. This ensures that only compatible Order Messages can be selected.
  4. Your Payment Configuration ID is automatically preselected using the default payment gateway.
  5. You may manually select a different payment gateway if required.
  6. Select the Order Message template that defines the message text, product display, and payment link sent to customers.
  7. Choose a Contact Custom Field to store extra customer information such as shipping address or customer notes.

  

  When Selling Physical Products

  1. If you are selling physical products through WhatsApp, it is essential to collect the customer’s shipping address before initiating payment.
  2. To do this, add the Ask Address action just before the WhatsApp Pay message in your Flow.
  3. This ensures that the shipping address is securely stored and properly linked to the order.
  4. As a result, the payment link is generated only after capturing the complete delivery details.

  

  1. Once the flow is fully set up, click on the Save button to activate it.

  

  How the Flow Works Once Saved

  • Once the Flow is saved, the payment process begins automatically whenever a customer places an order through your WhatsApp Catalog.
  • When an order is submitted from the WhatsApp app, the Order Received trigger is activated.
  • Based on your flow configuration, the Ask Address action is first sent to the customer on WhatsApp.
  • As soon as the customer replies with their address, the WhatsApp Pay action is executed and your configured Order Message is delivered to the customer.
  • This Order Message includes the products added to the cart along with all applicable charges as defined in the selected Order Message.

  The Order Message contains:

  1. All products added to the cart
  2. Applied tax rate, shipping charges, and discounts
  3. A secure payment link generated through your configured payment gateway
  4. A payment expiry timer based on your Order Message settings
  5. Two action buttons within the same Order Message:
     • Pay Now – Opens the payment panel directly and allows the customer to choose a payment method (UPI, PhonePe, etc.) and complete the payment instantly.
     • Review & Pay – Opens the full order summary where the customer can review products, applied charges, and discounts before completing the payment.
  6. If the Order Message is created with a 300-second (5-minute) expiry, the payment link will automatically expire after five minutes.
  7. Once the link has expired, the customer will no longer be able to complete the payment using that link.

Note: The Order Received trigger works only with WhatsApp Cart Order Messages. It will not fire for other types of Order Messages.

Using WhatsApp Pay Message with the "Custom Product" Order Message Type

When using the Custom Product type, you are not limited to the Order Received trigger. You can use any other supported trigger in Pabbly Chatflow except the Order Received trigger, such as Keyword, Regex etc.

1. For example, you may want to create a Flow that starts when the customer types a specific keyword. suppose you enter custom as a keyword

   

2. After selecting the trigger, you can place an Ask Address action (recommended for physical goods)

   

3. And Add the WhatsApp Pay Message

   

4. Inside the WhatsApp Pay message, select Custom Product as the Order Message Type.

   

5. In the next step, choose the required Order Message. Once selected, the system opens a dialog displaying all products included in that Order Message.

   Each product is displayed with the following details:

   • Product image
   • Product name
   • Quantity field

   By default, the quantity for every product is set to 1. You can adjust the quantities as per the requirement however, the system enforces a strict rule

   The total combined quantity of all selected products must not exceed 30

   

6. After selecting the products and setting their quantities, click the Save button as shown in the image above.

   

7. If the selected Order Message is of the Physical Product type, you must select a Contact Custom Field to store additional customer information related to the order.

   

8. Now, save the Flow by clicking the Save button.

   

Once the Flow is saved,

To test the setup:

1. Open WhatsApp.
2. Send the same keyword that you configured while creating the Flow.
3. As soon as the system receives the keyword, the Flow gets activated automatically.

If you have added an Ask Address action in the Flow:

1. The customer will first receive the address request on WhatsApp.
2. Once the customer replies with their address, the Order Message is delivered automatically with:
   • The selected products
   • Their respective quantities
   • Complete pricing details

Using WhatsApp Pay Message with the "Catalog Product" Order Message Type

The Catalog Product Order Message Type works the same way as the Custom Product type. The overall flow execution, order processing, and payment behavior remain exactly the same.

Prerequisites (Recommended)

Before using the Catalog Product Order Message Type inside the WhatsApp Pay Message, it is highly recommended to complete the following:

1. Ensure that the Catalog is synced successfully in Pabbly Chatflow
2. Make sure that all connected catalog products are also fully synced

This helps avoid any product visibility or delivery issues while sending the Order Message.

The “Catalog Product “ Order Message Type works exactly the same way as the Custom Product type. Once you select it, everything functions in the same manner, including:

• Flow triggering
• Order processing
• Ask Address step (for physical products)
• Order message delivery
• Payment link generation
• Tax, shipping, discount, and payment expiry rules

Using the "Payment Captured" Trigger

In addition with WhatsApp Pay, Pabbly Chatflow also provides a dedicated Payment Captured trigger event.

1. This trigger activates automatically whenever a payment is successfully completed by a customer. If you configured any flow with this trigger events.
2. This is helpful if you want to send a follow-up message then you will use this trigger events.

8. Date and Time Slot Booking Message

The Date and Time Slot Booking node allows you to create an interactive appointment or slot booking system directly inside your WhatsApp flow. Contacts can select a preferred date and time, while the system automatically manages slot availability, capacity tracking, and contact field updates.

This feature is ideal for appointment booking, consultations, demo scheduling, delivery date selection, callbacks, and more.

---

7. Duplicate Booking Prevention

To prevent multiple bookings in the same session:

• If a contact taps multiple slots, only the last selection is stored.
• If the flow runs separately again, it creates a new independent booking.

---

8. Race Condition Protection (Overbooking Prevention)

The system uses a:

• Check-before-insert
• Verify-after-insert

pattern to prevent overbooking when multiple contacts try to book the same slot simultaneously.

This ensures accurate capacity tracking even under high booking volume.

---

9. Message Content & Button Labels

You can fully customize:

Action Available in Pabbly Chatflow

1. Condition Action

Equal If-Else Condition

This condition verifies if the user input matches a predefined value. If the value matches, a "True" response is sent; otherwise, a "False" response is delivered.

Example: If a user enters "Bhopal" as their city and the condition is set to "Bhopal," the chatbot will return a "True" response. Otherwise, it will return "False."

• Trigger the Flow:
  • The flow will be triggered when a user sends a message containing the defined keywords.

Exists If-Else Condition

This condition checks whether a user has provided any input. If a value exists, a "True" message is sent; otherwise, a "False" message is returned.

Example: If a user submits their PAN card details, they receive a "True" response. If no details are provided, they receive a "False" response.

Time-Based and Date-Based Conditioning

This condition allows chatbots to provide customized responses based on specific time ranges.

Example: A chatbot can be programmed to send a welcome message between 10 AM and 7 PM. Messages received outside these hours can trigger an off-hour response. Similarly, date-based conditioning can be used for holidays and vacations.

User Message Condition

The User Message condition allows you to control the flow based on the text sent by the user. It is commonly used to filter messages before sending a response, especially at the start of a conversation.

How It Works

When a user sends a message, the system evaluates the message content using the User Message condition and routes the flow through the True or False path based on the rules you define.

---

How to Configure User Message Condition

Condition On

• Select User Message

Note:
Keywords can be defined only when “User Message” is selected as the condition.
Other condition types (Contact List, Contact Custom Field, Tags) do not support keyword input.

---

Select Condition

• Equal – Triggers when the message exactly matches one of the defined keywords
• Contains – Triggers when the message contains the defined keyword
• Exists – Triggers when any user message is present

---

Enter Keywords

• Add one or multiple keywords.
• The condition evaluates to True if the user’s message matches any one of the entered keywords.

---

Case Sensitive

• Enable this option to match exact letter casing.
• Keep it disabled for flexible matching (recommended).

---

Ask Address Action

This action enables the chatbot to collect the user’s address. The chatbot prompts the user to enter their complete address, which can then be stored for future interactions, deliveries, or support queries.

Example: If a business requires shipping details, the chatbot can request the address and store it for processing orders or deliveries.

3. Ask Location Action

This action enables the chatbot to request the user’s live location to facilitate location-based services. The user will be prompted to share their current GPS location using WhatsApp’s built-in location-sharing feature.

Example: If a service provider wants to allocate a technician for a home service, the chatbot can collect the customer’s location to assign the nearest available technician.

Example Use Case:

If a food delivery business wants to take customer orders and deliver to their exact location, this chatbot flow helps collect the order details and precise delivery address using live location.

• Trigger the Flow:
  • The flow will be triggered when a user sends a message containing the defined keywords.

4. Ask a Question Action

This action allows the chatbot to collect structured information from users, such as their name, email, phone number, or any other relevant details. You can define specific input fields to ensure accurate data collection.

Example: A chatbot for an online event may ask users for their full name and email address to send them a confirmation link.

• Trigger the Flow:
  • The flow will be triggered when a user sends a message containing the defined keywords.

5. Ask Media Action

This acton enables users to upload and share media files such as images, videos, documents, or audio clips. The chatbot can collect media for verification purposes, customer support, or documentation.

Example: A banking chatbot may ask users to upload a scanned copy of their identity proof for verification purposes.

• Trigger the Flow:
  • The flow will be triggered when a user sends a message containing the defined keywords.

6. Set Custom Field & Tag Action

This action captures user responses as attributes and assigns values accordingly. Users can also be categorized using tags.

Example:

• If a chatbot presents two quick reply buttons, "Show Offers" and "Not Interested," the chatbot assigns the "Optin" attribute to both.
• Clicking "Show Offers" assigns the "Optin" attribute with a "Yes" value, while "Not Interested" assigns it a "No" value.
• These responses can then be used for lead segmentation and further communication.

6. Remove Tag Action

This action removes selected tags from a contact and helps keep contact data clean and up to date.

When a flow is triggered using keywords or trigger events, any Remove Tag action placed inside the flow will automatically remove the selected tags from the contact.

• The flow starts when the user message matches the defined keyword or trigger condition.
• As the flow progresses, once it reaches the Remove Tag action, the specified tags are removed.
• This works for both keyword-based triggers and event-based triggers.

Example:
If a contact has tags like “Contact” or “Address” and the flow is triggered by the keyword “hello”, those tags will be removed automatically when the flow executes the Remove Tag action.

7. API Request Action

The API Request action enables a chatbot to integrate with external systems via API calls to fetch and send data dynamically. This ensures a personalized and efficient user experience.

For a detailed walkthrough, watch the tutorial: API Integration Tutorial

8. Connect Flow Action

This action allows you to link pre-existing flows together, streamlining development and saving time. It enhances efficiency and promotes a modular chatbot design.

9. Assign AI Assistant  Action

The Assign AI Assistant action allows you to assign an AI assistant to a specific chat flow, enabling automated responses and task management.

How to Use:

1. Select AI Assistant: Choose the AI assistant you have already created inside the AI Assistant module. This AI assistant will be assigned to the chat once the flow is triggered.

1. Start With: The flow allows you to start the conversation in different modes:

• Start Without Message: This triggers the AI assistant without sending an initial message.
• Use Client Message: The AI assistant will respond to the text message from the previous message or action in the flow.
• Welcome Message: Sends a static message directly to the client, bypassing the AI assistant for the first time.
• Personalized Message: Your message will be sent to the AI assistant, and its generated response will be sent to the client.

Once the AI assistant is assigned, it will automatically handle the conversation and provide relevant responses based on the flow.

Trigger the Flow:

• The flow will be triggered when a user sends a message containing the defined keywords. The AI Assistant takes over the chat and replies to the user.
  

10. Single AI Message Action:

The AI captures the client's input (such as location or preferences), generates a personalized response based on that input, and then saves the AI-generated response in the selected contact custom field. This contact custom field can be used later in the flow to enable dynamic follow-ups or further personalized interactions."

Example: If a user provides a location, the AI generates a tailored response (e.g., service availability based on that location) and saves it in the contact's custom field, making it accessible for further use in the flow.

How to Use:

1. Select AI Assistant: Choose the pre-configured AI assistant to send the response.

1. Start With: The flow allows you to start the conversation in different modes:

• Use Client Message: The AI assistant will respond to the text message from the previous message/action in the flow.
• Personalized Message: Your message will be sent to the AI assistant, and its generated response will be sent to the client.
• Store in Custom Field: Optionally, use the "Select Contact Custom Field" to save the AI assistant's response for future use, segmentation, or automation.
• Response Behavior: The AI assistant will send a single response to the user.

Trigger the Flow:

• The flow will be triggered when a user sends a message containing the defined keywords.

---

11.Delay Action

The Delay action allows you to introduce a delay in the flow before the next action is triggered. This feature helps to manage the timing of responses and actions, ensuring the flow happens at the right moment.

1. Delay For: Delay the flow for a specific amount of time (in minutes, hours, etc.).
   How it Works: You define the amount of time to wait (seconds, minutes, hours, or days), and the flow pauses for that exact period.

   Example: If you choose Delay For 10 minutes, the flow will stop for 10 minutes, then resume after the delay is over.

   Use Case: Ideal when you need to wait a specific amount of time before the next action triggers (e.g., waiting 5 minutes before sending a follow-up message).

How to use

1. Drag the Delay block where you want to pause.
2. Choose Delay For, pick unit (seconds/minutes/hours/days) and enter the number.
3. Connect the previous action → Delay → next action.
4. Save.

  ### What happens when the flow runs
  * The flow runs until it reaches the **Delay** block.
  * It pauses for the time you set.
  * After that time ends, the same flow continues and runs the next action automatically.  

1. Delay Until: Delay the flow until a specific time (e.g., a specific date or hour).
   How it Works: You set a specific date and time (e.g., 09/10/2025 03:00 PM), and the flow will wait until that moment before continuing to the next action.

   Example: If you set Delay Until 03:00 PM, the flow will pause until exactly 03:00 PM and then proceed.

   Use Case: Useful for scheduling actions at a precise future time, like sending emails at a specific hour of the day.

How to use

1. Drag the Delay block where you want to pause.
2. Choose Delay Until, Set the exact date and time (e.g., 09/10/2025 03:00 PM).
3. Connect previous → Delay → next and save.

What happens when the flow runs

• The flow pauses and waits until the exact date/time you set.
• At that moment the same flow resumes and runs the next action automatically.

1. Delay Until a Specific Weekday: Delay the flow until a particular weekday (e.g., next Monday) and optionally at a specified time on that day.

   How it Works: You choose a weekday (e.g., Monday) and set the time (e.g., 09:00 AM) to resume the flow on that day.

   Example: If you choose Delay Until next Monday at 09:00 AM, the flow will wait until Monday at 9 AM before proceeding with the next action.

   Use Case: Ideal for scenarios where actions should happen only on specific days, like starting a weekly campaign or follow-up reminders on certain weekdays.

How to use

1. Drag the Delay block where you want to pause.
2. Choose Delay Until a Specific Weekday, Pick the weekday (e.g., Monday) and time (e.g., 09:00 AM).
3. Connect previous → Delay → next and save.

What happens when the flow runs

• The flow waits until the chosen weekday at the chosen time.
• When that day/time arrives the flow resumes and runs the next action automatically.

How to Create a WhatsApp Chatbot Using Flow Builder?

Creating a chatbot using Flow Builder is extremely easy. All you need to do is choose the necessary elements (like Lists or Media Buttons) and drag & drop them onto the builder.

Step-by-Step Guide

1. Log in to your Pabbly Chatflow account.

2. Navigate to the left sidebar and select "Flows" to create a chatbot.

3. Click on "Add Flow" to initiate chatbot creation.

4. Upon clicking "Add," you will see a Flow Start. Here, you can choose how to trigger the chatbot flow using any of the available trigger events:

Available Trigger Events:

• Keyword/Regex Match
  • Trigger the flow when a user's message matches any defined keyword or regex pattern.
  • This method allows for advanced message pattern recognition using regular expressions (requires technical knowledge for regex creation). Learn more
• User Starts Conversation
  • Trigger occurs when a user initiates a new conversation.
• Template Selected
  • Trigger the flow when a user replies via a quick reply button on a sent template.
• WhatsApp Template Delivered
  • Triggered when a WhatsApp message template is successfully delivered to a contact.
• Contact Added
  • Trigger when a new contact is created manually or by lead.
• Contact Added to Contact List
  • Trigger when a contact is added to one of the selected contact lists.
• Custom Field Updated
  • Trigger when a custom field is added or updated for a contact.
• Tag Assigned
  • Trigger the flow when a tag is assigned to a contact during an update.

1. After selecting your preferred trigger event, drag and drop the required message type or action according to your business requirements.

Finalizing Your Flow

Once the flow is built according to your needs, follow these steps:

• On the top of the Flow Builder screen, you will see an option to name your flow.

• On the right corner, you can enable the toggle to make your flow active.
• Click on the Save button to save your created flow.

Now, once a user initiates a conversation, if any keyword or regex matches, the flow will trigger automatically. Similarly, if a conversation is initiated using templates and a quick reply button connected to a flow is clicked, the flow will get triggered seamlessly.
