## Parameters

#### Path parameters
- **groupId** (string)
  Unique 24-hexadecimal digit string that identifies your project. Use the [/groups](#tag/Projects/operation/listProjects) endpoint to retrieve all projects to which the authenticated user has access.

**NOTE**: Groups and projects are synonymous terms. Your group id is the same as your project id. For existing groups, your group/project id remains the same. The resource and corresponding endpoints use the term groups.
- **peerId** (string)
  Unique 24-hexadecimal digit string that identifies the network peering connection that you want to retrieve.

#### Query parameters
- **envelope** (boolean)
  Flag that indicates whether Application wraps the response in an `envelope` JSON object. Some API clients cannot access the HTTP response headers or status code. To remediate this, set envelope=true in the query. Endpoints that return a list of results use the results object as an envelope. Application adds the status parameter to the response body.
- **pretty** (boolean)
  Flag that indicates whether the response body should be in the prettyprint format.
