This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

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This event handler is obsolete.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!"); };
