Hello together,

At the moment I am using the example on the page: [Dashboard | ORS](https://openrouteservice.org/dev/#/api-docs/v2/matrix/%7Bprofile%7D/post). By specifying the destination parameter I get, according to my understanding, a many-to-one matrix. How do I now manage to generate a one-to-many? The body currently looks like this:

body = {“locations”:[[9.70093,48.477473],[9.207916,49.153868],[37.573242,55.801281],[115.663757,38.106467]],“destinations”:[0],“metrics”:[“duration”]}.

Thanks for the help

Hi @FuegoElo,

by using the `sources` parameter.
