Types of Chatbot Nodes

There are 3 types of chatbot nodes:

3.1 Send a Message => With no response required from visitors

Usually, this will be the last node in each branch of the chatbot. There are 5 types of messages, and no user input is expected:

  1. Text
  2. Image
  3. Video
  4. Audio
  5. Document (pdf, docs, etc)

3.2 Ask a Question => User input is expected and required validation

There are 2 types of answer reply:

  • Users can set a pre-defined list in the "Add answer variant" for customers to follow. With each reply, the user can drag the arrow into the subsequent node to create the next step. It means it will go to a specific node if the condition is matched. For E.g. if the user types hello, it will go to the next node matching hello. If the user types something else, it will go to the fallback node.
  • Users can save the customer's input data into a variable in "Save Answers in a variable". Note: this variable can be used anywhere through the chatbot as input for other nodes.

Users can type a question and can choose the validation rule under the Advanced option so that it can validate user input and return errors if not validated. There are 5 types of advance validation currently: * Number: User can define min and max value, along with Validation error message. If the user inputs any number, not in the range, the error message will be prompted until the user can input it correctly.

**. Date: If the user inputs any text that is not in date format, the error message will be prompted until the user can input it correctly.

***. Date + Time: If the user inputs any text that is not in date and time format, the error message will be prompted until the user can input it correctly.

***. Time: If the user inputs any text that is not in time format, the error message will be prompted until the user can input it correctly.

****. Pattern (Regex): There is a field "Regex pattern" for the user to input pattern rule eg National ID: If the user input any text that is not date format, the error message will be prompted until the user can input it correctly.

Question node with Expected Answers: if no condition matches (Expected Answer default answer is already implemented)

Below is an example of the existing default chatbot:

2.3.3 Conditions:

Condition is used to determine which node should go next based on the saved variables. It consists of 3 elements:

  • IF @ input: Where we write/select the variable(or/and use CustomParam) that we want to check.
    Note: The CustomParam is the parameter that we store the customer's input value in the current chatbot.
  • Condition Operator (equal to, not equal to, contains, does not contain, starts with, does not start with)
  • Value / Variable input: Where we write/select the variable or a value (string or number) that we want to check against the first variable
  • Add rule (AND & OR): To add more than one rule. TRUE output (Green dot), FALSE output (Red dot)
