Notes

  • Partial updates: Only provide the fields you want to change
  • Bot tokens: Setting a bot token to null clears the configuration but doesn’t unlink existing channel bindings
  • PVC size: Can only be increased, not decreased
  • Configuration merging: Configuration updates are merged with existing settings (not replaced entirely)
  • File operations: All file operations in a single request are applied atomically
