I'm trying to duplicate an ADFS config in Okta and having trouble figuring out how I can update the Realying party's url. In ADFS this would be editing the propertied of Relaying Party Trusts, then editing the Endpoints.
You can use our Template WS-Fed app from OIN, but I couldn't notice any Relying Party URL field in there. However, if you do need this on the app side it should be the same as the url you specify in the Service Provider Id field. If you need more informations regarding this, as it requires some details regarding you configuration you can open a ticket.
