# ACL Policy HTTP API
The `/acl/policy` endpoints [create](#create-a-policy), [read](#read-a-policy),
[update](#update-a-policy), [list](#list-policies) and [delete](#delete-a-policy) ACL policies in Consul.
For more information about ACLs, please see the [ACL Guide](/docs/guides/acl.html).
## Create a Policy
This endpoint creates a new ACL policy.

| ------ | ---------------------------- | -------------------------- |
| `PUT` | `/acl/policy` | `application/json` |
The table below shows this endpoint's support for
[blocking queries](/api/features/blocking.html),
[consistency modes](/api/features/consistency.html),
[agent caching](/api/features/caching.html), and
[required ACLs](/api/index.html#authentication).
| Blocking Queries | Consistency Modes | Agent Caching | ACL Required |
| ---------------- | ----------------- | ------------- | ------------ |
| `NO` | `none` | `none` | `acl:write` |
### Parameters
- `Name` `(string: <required>)` - Specifies a name for the ACL policy. The name

When no datacenters are provided the policy is valid in all datacenters including
those which do not yet exist but may in the future.
