**Status:** Fixed since December 2025

**How to recognise it**  
While the problem existed, when you requested document names for a tradeflow reference through Dockflow’s REST API, you got HTTP 501 Not implemented. You were trying to get document names and saw an error instead of the tradeflow’s document list.

**Which shipments this affects**  
This affected tradeflow references where you asked for document names through the Dockflow REST API. The fix covers fetching the document list for those references. It also covers deleting and updating documents for them.

**What changed**  
Dockflow now returns the tradeflow’s document list when you request document names for a tradeflow reference. Deleting and updating documents for the tradeflow also works.

**Is past data corrected?**  
Nothing to correct: the change affects how new data is read.

**How to check your shipment**  
Request the document names for a tradeflow reference through the Dockflow REST API. You should see the tradeflow’s document list, not HTTP 501. If HTTP 501 still appears, contact support.

**Do you need to do anything?**  
Nothing.
