"app" property in user response

[paulyoung]

This is present in the response when making a GET request to https://passport.thegrid.io/api/user, but isn't documented or shown in the schema.

Unless I'm mistaken it's the UUID of the app used to make the request.

It's not present when making a request to https://passport.thegrid.io/api/user/{id}, so can I assume that it's optional?

Yes, that's optional and comes from Passport.js. It is not linked with The Grid data entities.
