# Create alias address

`POST /api/fabric/alias_addresses`

Creates an alias address that forwards to an existing resource in your project. `name` and `resource_id` are required; `display_name` defaults to `name`, `channels` to all three, `codecs` to none, and `context` to `public`. The handler resource can't be changed later: to point an alias at a different resource, delete it and create a new one.

#### Permissions
