How to set the metadata parameter when adding geo points with the REST api?

Greetings,
the documentations states that I can add the optional metadata parameters like this:

PUT
/version/geo/points?lat=x.xxxx&lon=y.yyyy&categories=ABC,XYZ[url=undefined][&AAAA=foo&BBBB=bar]

However, this doesn’t seem to work, any help would be greatly appreciated.

Thanks,
Geo
