A `channel_ref` destination may not create a loop of channels. Requires a signed-in user token; with `realm_id`, a realm operator (or higher) with the `channels.manage.realm` permission on that realm; with `org_id`, a role with the `channels.manage` permission in that organization. One of `realm_id` or `org_id` is required. ## OpenAPI ````yaml /openapi/hub-by-tag/hub-notification-channels.yaml post /v1/notification_channels/create openapi: 3.0.3 info: title: 'CliqHub API: Notification channels' version: 1.0.0 description: >- Where notifications go.
