问题
I've read alot about flexible queries but unfortunatelly I couldn't find something satisfying yet.
I want the routing algorithm to ignore a street segmet, because its flooded or broken. Is that possible (maybe by putting geopoints into the GHRequest)? If it is, what is the best practice for the implementation?
update: Do i need to create a custom Weighting and set the forbiddenEdges which i get out of OpenStreetMap.org?
Thanks for answers

Yes, a custom Weighting is currently necessary where you feed GraphHopper edgeIDs (!= OSM IDs). Get these edgeIDs via LocationIndex.findClosest.
Please create an issue if you want to have this via web API.
