# Referencing Users and Groups ## Overview Abbey has the ability to reference users and group members stored externally for use in Grant Kits. These are most commonly used in two places: * Building a Workflow (I'd like Bob to approve, or members of this group to approve) * Creating an Output (assign the requester a permission) For understanding how these data can be used in Access Policies, please see [Policy Examples](/reference/access-policies/policy-examples.md). ## User References An Output block is templatized code change that assigns a user to a particular permission. In order to do that, we need to reference the identifier for a user. Below shows how an example for AWS Identity Center. ``` member_id = "{{ user.aws_identitystore.id }}" ``` ## Group References Abbey has the ability to use Group Memberships in the context of a workflow. For example, the below references a set of Users in a Google Workspace group. Abbey will send an approval to all members of that group, with only one (due to `one_of`) needing to approve for a user to get access. ``` one_of = ["{{ groups.googleworkspace.03oy7u2934pbgyw }}"] ``` --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
