                }
            ]
        }
    }
]

My aim is to customize users rest api : i would like to have a list of user social link users.

Is there a plugin i can use to :
1. to set the user social link ?
2. To get those links exposed by rest api ?

If you have an idea, i would like to know.

Thanks for your help.
