#

To enable constraints see [provider-specific constraints section](/configuration/commons/#provider-specific).
Please refer to the [Key Value storage structure](/user-guide/kv-config/#key-value-storage-structure) section to get documentation on Traefik KV structure.
!!! note
The option `useAPIV3` allows using Etcd API V3 only if it's set to true.
This option is **deprecated** and API V2 won't be supported in the future.
