## Update a channel

`client.Channel.Update(ctx, id, body) (*ChannelUpdateResponse, error)`

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

Updates `$includeInCrm` on a channel the caller can see. Only the channel owner — the member whose connected LinkedIn or WhatsApp account owns the DM — can change this. Anyone else receives `403`.

Supports idempotency via the `Idempotency-Key` header.

**[Required scope](/using-the-api/scopes/):** `channels:update`

### Parameters

- `id string`
