How find tags id to add tags when create topic via API

[dpausp (Tobias)]

AFAIK you don’t need tag ids. You can just pass the tag names.

Does anyone know if this should work in 2.0.0.beta9? Tags are not mentioned in the API docs for POST /posts.
I tried to create topics with tags="testtag" but got a HTTP 500 error.

From the logs:

NoMethodError (undefined method `-' for "testtag":String)
