When Slack cannot return the full channel list—for example, in a large workspace or during rate limiting—you can still add a destination by entering its channel ID or pasting a Slack link. Vibe checks that channel directly, so you do not need to wait for the complete workspace list.

Use this fallback anywhere the Slack channel picker appears. The steps below use an Automation Action as the example.

A channel ID usually starts with C or G, such as C0B3JEWQ86T. To use a link, open the channel or message in Slack and select Copy link.

The manual entry remains available while the workspace channel list is loading or unavailable.
