## Retrieve a channel

`client.channel.retrieve(stringid, RequestOptionsoptions?): ChannelRetrieveResponse`

**get** `/v1/channels/{id}`

Retrieves a single channel by its ID. Returns `404` if the channel is not visible to the caller — a private channel the caller is not a member of is indistinguishable from one that does not exist.
