When using detail=custom, document items sometimes appear in the response even though you didn't request them — and sometimes they don't. What determines this is whether you address the document by its identifier or search for it using a filter.
What's the difference
Address | What is returned |
| The header and items of the document. |
| Only the header. |
A filtered listing therefore returns only what you specified:
<winstrom version="1.0">
<faktura-vydana>
<id>2859</id>
<sumCelkem>3212321.33</sumCelkem>
</faktura-vydana>
</winstrom>
💡 If you need items even in a filtered listing, list the relation in detail=custom — for example ?detail=custom:sumCelkem,polozkyDokladu(nazev) — or add the relations=polozkyDokladu parameter. Both approaches are described in the article Getting document items.
