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.

Classification	Description
system field and custom field	system field is created by the system with pre-defined variable name and type, while custom field is defined by yourself
bot field and user field	bot 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 field	see 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:

Create Custom Field

Wow, now you are a master 👨‍🎓 of field! Let's try it out! 😎😎

You can create variables in 2 ways:

Place	Type Supported
in Contents section	user field & bot field
anywhere you need to map result to variable, e.g. Question step, Integration, etc	user field only

Create Custom Field in Contents Section

1. go "Contents" from the left sidebar

2. select User Fields or Bot Fields

3. use folder to organise your fields if needed

Click the blue "+ New User/Bot Field" button on the right side to create a field. "Field Name" is a must. You can use any character to separate words like underline or space. We suggest you keep the field name as concise as possible, to avoid any possible display issue.

After that, pick a variable type. Add default value or description if needed. (default value is for bot fields only)

Folders can be used to organise variables. Trust me, you will need it when your flow goes big. 🧐

Create Custom Field in Question and Action Step

To create new fields in for example, the question step:

Type in a new variable name in the "Enter Field Name" box and click it in the drop-down list. Select correspond variable type and here you go.

Another example, create in an integration:
