+This parameter is *optional*. A string representing a set of one or more resources and scopes the client is seeking access. This parameter can be defined multiple times

 permission ticket. The format of the string must be: `RESOURCE_ID#SCOPE_ID`. For instance: `Resource A#Scope A`, `Resource A#Scope A, Scope B, Scope C`, `Resource A`, `#Scope A`.
