api	Legacy ACLs - HTTP API	api-acl-tokens-legacy	The /acl endpoints create, update, destroy, and query Legacy ACL tokens in Consul.

-> Consul 1.4.0 deprecates the legacy ACL system completely. It's strongly recommended you do not build anything using the legacy system and consider using the new ACL Token and Policy APIs instead.
