Search Slack channels
Returns the workspace’s accessible Slack channels filtered by name. Designed as a discovery tool for feed-destination configuration — pass returned id values to Destination.slackDestination.channels. Fails with 400 SLACK_NOT_CONNECTED when the Slack integration isn’t installed for the workspace, so an EMPTY list unambiguously means ‘connected, but nothing matched the query’.
Authorizations
Clerk API key. Create one in Settings → API Keys. Pass as Authorization: Bearer <key>. Keys carry a scope — read, write (implies read) or admin (implies write) — chosen when the key is minted. Each operation's security requirement (and its x-required-scope extension) names the minimum scope it needs; request the least-privileged key that covers the operations you call.
Query Parameters
Case-insensitive substring match against channel name. Omit to list every accessible channel.
"releases"
Opaque pagination cursor from a previous response's pagination.nextCursor.
How many Slack API pages to fetch per call (1–10). Higher values increase latency but reduce client-side pagination. Default 2.
