Integration variables

By writing expressions, you can access integration variables, which are context variables that are specific to integrations (such as the web chat and phone integrations). All integration variables are contained in the system_integrations JSON object, which you can access using the following expression:

${system_integrations}

The system_integrations object has the following structure:

{
  "channel": {
    "name": "{channel_name}",
    "private": {
      "user": {
        "id": "{user_id}",
        "phone_number": "{phone_number}",
        "name": "{name}"
      }
    }
  },
  "chat": {...},
  "voice_telephony": {...},
  "text_messaging": {...},
  "whatsapp": {...},
  "slack": {...},
  "facebook": {...},
  "teams": {...}
}

`channel`

Always included. This object contains general information about the channel that is being used to communicate with the assistant.

Properties

Properties contained in the private object are treated as private variables, which are not included in logs.

Example expressions

This expression tests whether the customer is using the Chrome browser:
```
${system_integrations}.chat.browser_info.browser_name.equals("chrome")
```
You might specify this expression as the value for a boolean session variable, which you could then use in a step condition. For example, if your website supports only Chrome, you could have a step conditioned on this variable being false and has the following output: I see you aren't using the Chrome browser. Some features of our website work only on Chrome.
This expression tests whether the current page URL contains the string payment.html:
```
${system_integrations}.chat.browser_info.page_url.contains("payment.html")
```
You might use this expression in a step condition in order to avoid telling customers to navigate to a page they are already viewing. For example, in an action for paying a bill, you could have a step conditioned on this variable being false and has the following output: First, click **Pay bill** to navigate to the bill payment page.

`voice_telephony`

Included only if the phone integration is in use.

The voice_telephony object contains both response and request properties. Request properties are values that are set by the phone integration and provide information about the call. Response properties are input values that you can modify in your actions to send logging data or to change configuration options for the call.
