The application we made in the querying section isn't very useful. For one it only supports a single user's contacts, and secondly it forgets all the user's contacts whenever the system restarts. In this section we'll solve the multi-user problem by exploiting an important feature of any blue-blooded actor system: the hierarchy.

curl -X GET -i http://localhost:3000/api/:userId/contacts

curl -X GET -i http://localhost:3000/api/:userId/contacts/:id

curl -X POST -H 'Content-Type: application/json' -i http://localhost:3000/api/:userId/contacts --data '{"name": "Test", "surname": "User"}'

curl -X PATCH -H 'Content-Type: application/json' -i http://localhost:3000/api/:userId/contacts/:id --data '{"company": "Bianco Royal"}'

• the :id has to be replaced with the UUID of a contact record
• the :userId has to be replaced with the id of the user of a contact request
