The Variable condition block is used to compare a variable with a value or another variable. You can use it to create conditional logic in your bot based on user inputs, stored values, or system variables.

​
Components of a variable condition

  • Label: A descriptive label for the condition, which will be displayed in the block on the canvas. This is optional and can be skipped.
  • Variable: The variable or value that the block will evaluate. The variable can be a user input, a stored value, or a system variable.
  • Comparison operator: The operator that the block will use to compare the variable with the value you specify. You can choose from a list of comparison operators, such as “equals,” “greater than,” “contains,” etc.
  • Value: The value that the block will compare with the variable. This can be a static value or a variable for dynamic comparisons.

Examples

​
1. Real estate bot

In a real estate bot, you can use conditions to check if the user is looking to buy or rent a property and display properties accordingly.

You can create two conditions:

  • Condition 1: User input contains “buy”
  • Condition 2: User input contains “rent”

Here’s how to set it up in the editor:

Once you have set up the conditions, you can define the paths for each condition. Here’s an example:

Based on the above, here’s how the bot will respond:

  • If the user input contains “buy,” the bot will respond with Great! Let me show you our available properties for sale.
  • If the user input contains “rent,” the bot will respond with Sure! We've got amazing properties for rent. Here's the list.
  • Else if none of the conditions are met, the bot will respond with I'm sorry, I didn't understand. Please respond by typing "Buy" or "Rent".

2. Filtering job application candidates

Let’s say a candidate is applying for a job through the bot and you want to qualify them based on the following criteria:

  • Location: New York
  • Willing to relocate: Yes
  • Years of experience: 3 or more

You can set up the following conditions:

Once you have set up the conditions, you can define the paths for each condition. Here’s an example:

Based on the above, here’s how the bot will respond:

  • If the candidate is from New York, willing to relocate, and has 3 or more years of experience, the bot will respond with Congratulations! You've been shortlisted for the next round of interviews.
  • Otherwise, the bot will respond with Sorry, you are not qualified for this job opening. We'll keep your application on file for future opportunities.
