pheonix api options call shows empty params

问题:

I am making a phoenix api for my react frontend and I am sending a post request with an object of objects, and I figured that I need to use options in the api to get them beause with post it just failed, but now the params are empty. Why is that?

What I send:

axios
.post(PAYMENT_SERVER_URL, {
  description,
  email: token.email,
  source: token.id,
  subscriptionID
})

api router:

pipeline :api do
  plug(:accepts, ["json"])
end

scope "/api", MyApiWeb do
  pipe_through(:api)

  options("/users", UserController, :create)
end

api usercontroller

def create(conn, params) do
  IO.puts(options)
end

for now I'd be very happy with just logging it out.
