Variables or properties or entities are data storage entities. Variables are a way to store data or the user input in a format to reuse that detail in the chatbot conversation or to store the information.
Variables are helpful when you need to personalize the conversation by saving the user name in a variable for using it during the conversation or if you want to store user details and pass them on to external systems or generate reports.
You can save user details or inputs in a variable for getting user insights as well.
Types of Variables
Generally, these are of the below kinds:
- System - These are generally global contexts, not under the direct control of a brand. For eg, the current date, and time.
- Global Session - These are brand-level variables. They are defined by the brand and have the same value across all end users. For example, counter, brand name, etc.
- Local Session - These variables are global for a customer/end user. For example, customer name, email address, etc.
- Local or Session-based - These are session-based variables, whose scope can restrict to a particular session. For eg, after the 24-hour session on WhatsApp, the local variables can restart again
- Event-based - These are external variables whose scope is customer based but can be true for a segment of customers. For example, the channel of the message received from the customer, customer message, type of events, autoresponders, etc. These can be viewed or used but should not be edited.
Variable Management Elements
- Name (Unique identifier)
- Data Type (the kind of data it can store, for eg, text, number)
- Dummy Value (Some initial value for eg, 0 for a number or another constant)
There are three data types that can be stored:
