Routing through access=private streets on osm

Greetings Hopper :slight_smile:

I am speaking for a small developing team that currently develops a small routing service for the BUGA2019 in Germany Heilbronn.
The BUGA2019 is basically a big garden and all streets are tagged with access=private, since you can only access this park if you pay money.
My question is, if I have two points, how can I route through this park (using the streets, that are private).

Feeling a bit lost here :confused:

Thanks for you help!


I had the same requirement.
