The Trigger Intent feature lets you manually activate a specific Intent in your Flow using the syntax cIntent: followed by the Intent name. This feature overrides the default Intent mapping process, giving you precise control over the Flow’s next steps based on user input, such as a message or button click. Use the Trigger Intent feature when you need to:
  • Skip NLU processing and direct the Flow to a specific Intent.
  • Ensure consistent navigation in response to button clicks or system actions.
  • Improve the user experience by minimizing errors from misinterpreted user input.

​
Key Benefits

  • Precise Flow Control. Ensures the correct Intent drives the Flow forward.
  • Postback Support. Triggers a specific Intent smoothly when a user clicks a button with a Postback value.

​
Prerequisites

Before using this feature, ensure the following:
  1. You set up your Flow with specific Intents for the scenarios you want to trigger.
  2. You have a Say, Question, or Optional Question Node in the Flow editor.

​
Restrictions

  • This feature bypasses full NLU processing, preventing default replies from triggering and automatically setting the Intent score to 1. Don’t use this feature for general NLU analysis.

​
How to Use

  1. In the Flow editor, identify the Intent needed to continue your Flow. For example, Continue Booking.
  2. In a Say, Question, or Optional Question Node, use the syntax cIntent:Continue Booking as a Postback value in Output Types that support Postbacks. Follow these syntax rules:
    • No space should follow the colon, though spaces within the Intent name are allowed. For example, cIntent:Continue Booking.
    • (Optional) Add a text for Slot parsing after a pipe symbol (|). For example, cIntent:continueBooking|book tomorrow.

​
How to Test

Test the feature in the Interaction Panel:
  1. Open the Interaction Panel and enable Debug Mode.
  2. Test your Flow with the cIntent:continueBooking Postback value. The system debug message shows: 
    Intent Match
Flow: Slots
Intent: Continue Booking
Intent score: 1
  3. Test your Flow with the cIntent:continueBooking|book tomorrow to verify Slot extraction, for example, tomorrow. The system debug message shows: 
    System Slot Match
