I realize this is a year later but we're looking to do this now and running into roadblocks. 

Drew,

Do you know if there is currently any way to allow connections from Epic as a trusted source without a true user login? Something like a certificate-based key exchange where Epic passes the Epic user sign-on or a generic service account embedded in the link used to authenticate the user? We do not want our users to have to login as themselves to access Service Now. Is this even possible now? Our vendor is telling us it isn't possible but without it I'm not sure we can move forward with this integration.

Thanks,

Jeff Heffner
