There are various ways to integrate your Informizely survey with Intercom, among which:
This can be done using a "timed action". When the user provides an answer to a question that you want to trigger the Intercom messenger, e.g. an answer to a single choice question or the click of a button, navigate to a survey page that has a timed action to open the Intercom chat window, either immediately or after a specified number of seconds.
You can read more about timed actions here.
To embed an Informizely survey in Intercom messenger you should create an "embedded survey"
for app "Intercom". After editing and publishing the survey you can copy the HTML for the first question on the survey's settings page and paste it directly for use in Intercom.
You can also copy only the answer links, so that you can use them as is, or style and modify them to your liking.
For embedded surveys, optional follow-up questions to the initial embedded question are asked in a full page survey on the Informizely site.
Using Informizely's event tracking integration it is easy to record survey events in Intercom, just call Intercom('trackEvent', event-name, optional-metadata) when the survey events that you want to track occur. You can choose your own event names and metadata, the example below provides a possible implementation:
