This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

The RTCPeerConnection.onidpvalidationerror event handler is a property containing the code to execute whent the idpvalidationerror event, of type RTCIdentityErrorEvent, is received by this RTCPeerConnection. Such an event is sent when the associated identity provider (IdP) encounters an error while validating an identity assertion.

This event handler is obsolete. You should instead detect IdP validation errors by watching for the promise returned by RTCPeerConnection.peerIdentity to be rejected.


peerconnection.onidpvalidationerror = function;


  • function is the name of a user-defined function, without the () suffix or any parameters, or an anonymous function declaration, such as function(event) {...}. An event handler always has one single parameter, containing the event, here of type RTCIdentityErrorEvent.


pc.onidpvalidationerror = function(ev) { alert("onidpvalidationerror event detected!"); };
