https://auth.roblox.com/v1/authentication-ticket error

response = await client.requests.session.post("https://auth.roblox.com/v1/authentication-ticket", headers={"referer": f"https://www.roblox.com/games/{placeId}"})

I tried to create a POST and apparently not all the necessary parameters are provided as it gives an error. rbx-authentication-ticket, this appears to not be a valid header.
