System Variables

The Set Chat Variable action can create new variables or reference existing system variables:

_user_input

Captures and stores the person's input at each interaction stage within the AI assistant. It is dynamic, meaning that it updates automatically each time the person enters a new input.

---

_lang

Records the language identified from the person's input during each interaction.

---

_channel_profile

Holds profile information for the person as obtained from the messaging app. It includes details such as the person's ID in Yola, their display name, the type of channel they're using, their profile picture URL, and other information that varies depending on the app.

For people connecting through Webchat, this variable also captures additional information if certain features are activated in the Webchat settings, such as:

• Data from a pre-chat form

• Person's location and IP address

Example

{
	"id": JSHSFHDHBJVKOISFIU,
	"display_name": "Weiying",
	"location": "MY",
	"email": "[e-mail]",
	"phone_number": "34898483245",
	"ip_address": "0.0.0.0",
}
