Postmessage Listeners

Hello,

With regards to embedding a Yext Locator via an iFrame on a client hosted web template, does Yext offer postmessage listeners? This could provide functionality to refresh the iFramed locator without the entire client hosted page requiring a refresh (i.e. refreshing the iFramed Locator as a result of an interaction in a different web component which may reside on the web page which is housing the iFramed content)? Thanks, Sam
