Wordpress - REST API - How to set up roles

Wordpress REST API allows roles as array.

But when you try to set roles as it is, it throws error.

Correct list of roles:

• administrator
• editor
• author
• contributor
• subscriber
• customer

As you see, all of these role names must be in lower case.

For example:

$user = WordpressAPI::createUser([
'username' => 'test',
'email' => 'test@gmail.com',
'password' => '123456QQQ',
'roles' => ['subscriber'] 
]);

And you can add your own roles that you created in system.
