If one is allowed to put multiple values on single Query Parameter,
should the parameter name be in singular or plural form?
/user?status=1,2,3
vs
/user?statuses=1,2,3
I tried to google it but no one covers about this specific matter
As your endpoint allows a user to query for a number of statuses, then you would use the plural of status i.e.
/user?statuses=1,2,3
If your endpoint only allows a user to query for a single status you would use the singular i.e.
/user?status=1
