The Userback API utilizes Filtering and Sorting based on Microsoft API guidelines syntax, excluding the use of $.

Filtering

In order to filter records you can perform an equality check like so:

https://api.userback.io/rest/1.0/feedback?filter=name eq 'Joe'

Or utilizing gt to find all feedback with more than 5 votes:

https://api.userback.io/rest/1.0/feedback?filter=voteCount gt 5

Filters can also be combined using the and/or operators:

//api.userback.io/rest/1.0/feedback?filter=voteCount gt 5 and type eq "BUG"

Sorting

https://api.userback.io/rest/1.0/feedback?orderBy=modified desc
