Trigger

Updated on January 20, 2022

Trigger is where you can set up keyword capture, or capture by regex, e.g. patterns of a variable, or sentences and words.

How is this useful?

Triggers allows the bot to respond to users with the right messages at the right time, and direct users through a flow, thus being able to engage with users more proactively.  When certain keywords or regex are used by your end-user, a particular flow will start.

Examples of keywords or regex that can be captured:

  • NRIC number
  • Phone number
  • Email address

How do I set up a trigger?

  1. After a content node has been created, click on ‘+’, followed by ‘Trigger’ to add a trigger. 
  2. Select the Trigger type. 
  3. Enter keywords if using keywords. 
  4. The content node that should appear after the flow is triggered will be displayed at Actions > goto. 
  5. Click on the tick icon on the header bar to save the node. 

Alternatively, you may create a trigger in the Triggers tab.

  1. Click ‘+’ and fill in the trigger name in the text box.

    For triggers that belong to the same category, add an underscore (‘_’) between the words, e.g. ‘feedback_name’, ‘feedback_email’.  When you view the feedback category in the triggers list, you will be able to view all triggers relating to feedback.
  2. Click the tick icon to create the trigger. 
  3. Select the Trigger type. 
  4. Enter keywords if using keywords. 
  5. At Context, enter the node id of the content node that appears before the user is required 
  6. At Actions, select the appropriate action.  The most common step is “goto”, which is to point to a content node in “Data” and key in the content node name there.
  7. Click on the tick on the header bar to save the trigger. 

Validation Check

  • If trigger has same conditions, same context, and same text patterns, it will be flagged as duplicated and invalid.
  • Text patterns should not be wrongly configured to be ‘open ended’.  When a trigger is left ‘open ended’, all values would be a valid value, causing the chatbot to be misconfigured.

    ‘Open ended’ example: “/hello|hi|yes|/i”
