When you create or refresh a Developer or Developer Pro sandbox, you must provide access to the sandbox using a public group. This feature improves sandbox creation times, enhances the login experience, and increases sandbox security. This feature doesn’t apply to Partial Copy or Full sandboxes
Where: This change applies to all newly created or refreshed Developer and Developer Pro sandboxes on all instances (Salesforce first-party and Hyperforce) created using the Salesforce Sandbox Setup page
When: This feature will be rolled out in the Sandbox Setup page beginning in Winter ’25. Starting in Spring ’25, when using the Tooling API, the ActivationUserGroupId field on the SandboxInfo object will be required. To avoid losing the ability to create or refresh Developer and Developer Pro sandboxes, use API version 60.0 or later
Who: All users in the production org with the Manage Developer Sandboxes or Manage Sandboxes user permission
