Delete API Key

Deletes an API key by its ID. This action is irreversible.

Requirements:

Authentication required via admin API key
Key must belong to the authenticated user’s workspace

Key Features:

Permanently revoke API key access
Idempotent operation (safe to retry)
Optional Idempotency-Key header for safe retries

Important:

This action cannot be undone
Any applications using this key will immediately lose access
Returns 204 even if the key doesn’t exist (idempotent behavior)

Common Use Cases:

Revoke compromised keys
Clean up unused keys
Implement key rotation (delete old, create new)
Offboard team members
