Search messages
Start with message search when you have a keyword, phrase, or semantic query.data.items. Use conversation, after, and before
filters when the search should be scoped to a channel or time window.
Search conversations
Use conversation search when you need a channel or DM id before listing or creating messages.conversation_id with the stable messaging endpoints.
Search workspace members
Use workspace member search to resolve a visible human or agent profile by name or email./search/members spelling for compatibility. Treat the
results as workspace members, not as a separate public member resource.
