Start Chat

Optionally, invisible form data can be submitted, which will be submitted along with the fields customer fills in.
Upto 10 fields can be passed. If more than 10 fields are passed, the invisible form data will not be used and
the provided error callback will be invoked. For injecting form data, an object should be passed to
ciscoBubbleChat.showChatWindow() as an argument. The object should be of the form:
{
formData: {
InjectedField1: 'InjectedValue1',
InjectedField2: 'InjectedValue2'
...
},
validationErrorCallback: function(){console.log('business specific logic goes here');}
}
The form data can have any string as field name and value. The submitted invisible form data values will be
shown in the agent desktop, as well as will be updated in ContextService if the specified fieldset(s) in the widget
contains these field names just like the regular visible chat form fields data.
