# Add Entries to Project IP Access List

`POST /api/atlas/v2/groups/{groupId}/accessList`

Adds one or more access list entries to the specified project. MongoDB Cloud only allows client connections to the cluster from entries in the project's IP access list. Write each entry as either one IP address or one CIDR-notated block of IP addresses. This resource replaces the whitelist resource. MongoDB Cloud removed whitelists in July 2021. Update your applications to use this new resource. The `/groups/{GROUP-ID}/accessList` endpoint manages the database IP access list. This endpoint is distinct from the `orgs/{ORG-ID}/apiKeys/{API-KEY-ID}/accesslist` endpoint, which manages the access list for MongoDB Cloud organizations. This endpoint doesn't support concurrent `POST` requests. You must submit multiple `POST` requests synchronously.
