In a "code" block

Basically within it trying to error the transform when date invalid 

Yeah it is probably the way too do it; just it transforms it as part of that send so it's a loop it in same router job or pass it on to another router to go to the operation so was wondering if there was another way without this but doubt there is 

Thanks although not going into technical too much I think this was the info I wanted. And there is a useful link for jwt down this route. https://community.intersystems.com/post/creating-rest-api-jwt-authentica...
