Go SDK's feature implementation is a bit delayed: https://github.com/line/line-bot-sdk-go/issues If the SDK supports a generic HTTP request method like this, users can use all new features without waiting SDK's implementation: ``` import ( "github.com/line/line-bot-sdk-go/linebot" ) func main() { rawBody = ....; bot, err := linebot.New("<channel secret>", "<channel access token>") rawResponse = bot.Post("/path/to/new/api", rawBody) } ```
