Replace all permissions on a key with the specified set in a single atomic operation. Use this to synchronize with external systems, reset permissions to a known state, or apply standardized permission templates. Permissions granted through roles remain unchanged. Important: Changes take effect immediately with up to 30-second propagation across regions. This is a complete replacement operation — all existing direct permissions not included in the provided list will be removed. Required permissions:Documentation Index

Usage
Flags
The key ID to set permissions on. This is the database identifier returned from
keys.createKey (e.g., key_2cGKbMxRyIzhCxo1Idjz8q). Do not confuse this with the actual API key string that users include in requests.Comma-separated list of permissions. Replaces all existing direct permissions with this new set. Providing an empty value removes all direct permissions from the key. Permissions granted through roles are not affected. Any permissions that do not already exist will be auto-created if your root key has sufficient permissions.
