Build smarter Guided Conversations with Fork Blocks

Build smarter Guided Conversations with Fork Blocks

When your customers arrive on your support channel, they're not there to explore. They are usually confused and stuck while trying to fix something important. We understand how stressful that moment can feel and we want your bot to make things easier, not harder.

A well designed Guided Conversation takes away this confusion. At the heart of those flows lies one powerful tool: the Fork Block. When you pair it with a few smart techniques, it can turn a basic bot into a friendly assistant your users trust.



What Fork Blocks actually do   

Think of Fork Blocks as your bot’s decision maker. They split the flow into different paths based on conditions.
The bot behaves exactly the way you expect:
  1. If the customer says X, respond with Y
  2. If that does not match, check the next thing
  3. If nothing fits, take them to a helpful fallback
Nothing is guessed; each action is based on your logical configuration.


Example

A customer contacts your support bot on WhatsApp.
The bot asks: “What do you need help with today?”
Options:
  1. Order related help
  2. Account help
  3. Something else
Your Fork Block simply checks what the user tapped or texted and takes them to the correct flow. A Fork Blocks split your flow into different paths based on conditions.

Customer chooses
Bot should do
Order related help
Bot asks for the order number and shows order status.
Account help
Bot verifies mobile number and shows account options.
Something else
Bot shows a short menu to guide the user.

This feels smooth because the bot reacts instantly based on the user’s choice.
  

Why this matters for your customers     

Fork Blocks help you:
  1. Personalise every step
  2. Reduce back and forth
  3. Send users to the right answer faster
  4. Prevent unnecessary agent escalations
This directly improves resolution rates across channels, WhatsApp, Messenger, Instagram and more.
 

Advanced techniques

Below are the techniques that can take your Fork Block logic from basic to professional level. The transitions between them are natural, since each one uses Fork Blocks in a different but complementary way.

Fork with IM Variables

When a customer messages your WhatsApp bot, Guided Conversations can use one of their credentials, such as their phone number (IM Variable), to fetch details from your backend system via a webhook. This equips the bot with key information about the customer, like whether they are on a Gold or Free edition, without needing to ask.
Your Fork Block then uses this information to personalise the conversation instantly.

Gold customers: "Hi, welcome back. You are on Gold support. Here are your recent tickets."
Free customers: “Hi. Please share your order number so I can help you.”
If customer type isn’t available: “Just to help you better, are you a Gold customer or a Free customer?”

This keeps the conversation smooth and personalised without asking the customer to repeat basic details.

Fork Block with Operation Block      

Some decisions depend on numbers. For example, a customer might tell you their quantity and price, and you need to decide what assistance level they should get. Instead of asking customers to calculate things or writing long explanations, let the Operation Block do the math.

Example  

  1. A customer shares quantity and price.
  2. Operation Block calculates total value.
  3. Fork Block decides how to assist the customer based on that value.
 
Total Value
What your bot offers
Above 20,000
Priority callback
5,000 to 20,000
Connect to a human agent
Below 5,000
Automated

Here, the Fork Block evaluates the result of the Operation Block and chooses the best path. This keeps the flow clean and avoids long explanations.


Fork Block with Webhook Block

Sometimes your bot needs to make decisions that depend on information stored outside the Guided Conversation flow. For example, checking a warranty, subscription, customer tier, or order status.
Combining a Fork Block with a webhook is a powerful tool in this situation.

How it works

  1. The user enters a detail (for example: order ID)
  2. A webhook sends this to your backend system for a status check
  3. Your system returns a simple response such as:
    1. SHIPPED
    2. OUT_FOR_DELIVERY
    3. YET_TO_SHIP
  4. The Fork Block reads this result and decides the next step.
 
Example  
User asks “What’s my order status?” and enters an order number.
  1. Webhook checks your system.
  2. Response = OUT_FOR_DELIVERY
  3. Fork Block routes to “Your order is on the way. Here’s your tracking link.”
  4. If response = YET_TO_SHIP,  the Fork Block routes to “Your order is being prepared. We’ll notify you once it ships.”
This keeps the flow neat and helps customers move faster.

How the three come together to create a smooth, intelligent WhatsApp bot   

In real-world WhatsApp flows, these three techniques often work together.
  1. IM variables help trigger the backend and retrieve user details
  2. Webhook verifies backend information
  3. Operation Block calculates values
For example, you can identify the user via their mobile number, calculate the cart value using an Operation Block, and verify their membership tier through a webhook all in one flow.
 

Best Practices  

  1. Map your branches before building: Sketch your decision paths on paper first
    1. This prevents confusion when your flow grows; it will be easy to see where each condition leads
  2. Use specific conditions first and general ones later
  3. Always include an Else path

Final Thought  

Fork Blocks work on every channel supported by Guided Conversations, not just WhatsApp.
When you combine them with Webhooks, Operation Blocks and Session Variables, you create flows that feel structured, reliable and human-aware, without complexity for the user.
