# `CCXT.WS.Subscription.MethodAsTopic`
[🔗](https://github.com/ZenHive/ccxt_client/blob/main/lib/ccxt/ws/subscription/method_as_topic.ex#L1)

Coinex/Phemex-style subscribe frame where the method name IS the channel.

    %{"method" => "ticker.subscribe", "params" => [], "id" => 1}

Callers pass full method names like `["ticker.subscribe"]` in the
channel list. Only the first entry is used — callers that need multiple
subscriptions call `subscribe/2` once per channel. `unsubscribe/2`
converts `.subscribe` suffixes to `.unsubscribe`.

Config keys: `:op_field` (default `"method"`), `:args_field`
(default `"params"`).

Not wired in `CCXT.WS.Config` today (no priority-tier exchange uses it).
