SELECT AssigneeId,Id,PermissionSet.Name FROM PermissionSetAssignment WHERE AssigneeId = '< id >' AND PermissionSetId = '< id >'

On firing above query using API (/services/data/v20.0/), i am getting error mentioned below:

Array( [message] => sObject type 'PermissionSetAssignment' is not supported [errorCode] => INVALID_TYPE )

I have tried changing the API versions like (/services/data/v22.0/) and (/services/data/v40.0/) but no luck...

what do i need to change in salesforce ?

    Please check curl end point and headers and match with Workbench, there must be a difference @NailDavid

    @NailDavid PermissionSetAssignment is available in 22.0 and higher; it is most likely that you didn't set the version correctly in your PHP code. 22.0 or any higher version would suffice.
