Field variable

Before the detailed introduction of each step, let’s take a look at what is field(variable). It might take you a moment but this is essential to know more about the system. Field, aka variable, is a container to hold a value.

system field and custom fieldsystem field is created by the system with pre-defined variable name and type, while custom field is defined by yourself
bot field and user fieldbot field is shared in the whole bot, while each user has his/her own set of user fields
text field, number field, boolean field, date field, datetime field and JSON fieldsee variable type

User Field

User field belongs to users. For example, each user has their own name and email address. So “name” and “email” are user fields.

Bot Field

Bot field belongs to the bot. For example, a restaurant bot holds an address and contact number of the restaurant. So “restaurant_address” and “restaurant_contact” should be created as bot fields. Because you don’t want to manage different addresses or contacts of your restaurant for every user.

System Field

System field is created by the system with pre-defined variable name and variable type. There are system bot field and system user field:

Some system fields only exist in the specific channel. Check the table below for how to edit system field:
