# Create One Access List Entry for One Organization API Key

**POST /api/atlas/v1.0/orgs/{orgId}/apiKeys/{apiUserId}/accessList**

## Parameters

#### Path parameters
- **orgId** (string)
  Unique 24-hexadecimal digit string that identifies the organization that contains your projects. Use the [/orgs](#tag/Organizations/operation/listOrganizations) endpoint to retrieve all organizations to which the authenticated user has access.
- **apiUserId** (string)
  Unique 24-hexadecimal digit string that identifies this organization API key for which you want to create a new access list entry.

#### 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.
- **includeCount** (boolean)
  Flag that indicates whether the response returns the total number of items (**totalCount**) in the response.
- **itemsPerPage** (integer)
  Number of items that the response returns per page.
- **pageNum** (integer)
  Number of the page that displays the current set of the total objects that the response returns.
- **pretty** (boolean)
  Flag that indicates whether the response body should be in the prettyprint format.

## Body parameters
Content-type: application/json
Access list entries to be created for the specified organization API key.
- **cidrBlock** (string)
  Range of network addresses that you want to add to the access list for the API key. This parameter requires the range to be expressed in classless inter-domain routing (CIDR) notation of Internet Protocol version 4 or version 6 addresses. You can set a value for this parameter or **ipAddress** but not both in the same request.
- **ipAddress** (string)
  Network address that you want to add to the access list for the API key. This parameter requires the address to be expressed as one Internet Protocol version 4 or version 6 address. You can set a value for this parameter or **cidrBlock** but not both in the same request.
