This endpoint creates rules to allow only the specified domains to federate with your server. This only applies when [LIMITED_FEDERATION_MODE](../../admin/config#limited_federation_mode) is enabled. This is the inverse of the [Domain Blocks](./domain_blocks) functionality, and cannot be used to override a wild-card domain block.

## List all allowed domains {#get}

```http
GET /api/v1/admin/domain_allows HTTP/1.1
```

Show information about all allowed domains.

**Returns:** Array of [Admin::DomainAllow]({{< relref "entities/Admin_DomainAllow" >}})\

Because DomainAllow IDs are generally not exposed via any API responses, you will have to parse the HTTP `Link` header to load older or newer results. See [Paginating through API responses]({{<relref "api/guidelines#pagination">}}) for more information.

```http
Link: <http://mastodon.example/api/v1/admin/domain_allows?limit=2&max_id=2>; rel="next", <http://mastodon.example/api/v1/admin/domain_allows?limit=2&since_id=1>; rel="prev"
