I have succesfuly add my custom REST API to IONAPI Gateway. I can call all methods which are not authorized with success. But methods which are secured with JWT Token could not be called, I get 401 error which is expected. I try to setup target endpoint security with JWT Target Authentication option but with no success. I know how to setup JWT Header and JWT Payload and Alghoritem, what I dont now is what the Key option means and which value must be set. Can anyone help me. I use InforOS on premiss version 12.0.40.
