Filtering Charges Using the REST API

Direct filtering of price list items that have fees is not available in the API.

A possible solution is to use the price list and the fees relation:

https://demo.flexibee.eu/c/demo/cenik.json?limit=0&relations=poplatky

This returns an overview of all items including fees; however, you then need to exclude those that do not have a fee.

Alternatively, the approach can be "reversed" by filtering through the fee record:

https://demo.flexibee.eu/c/demo/poplatek/(cenik eq 'code:RECYKLACE 5').xml?detail=custom:cenikOtec(kod,nazev)&includes=/poplatek/cenikOtec
