+# Overview
+This code snippet helps ServiceNow developers manage group memberships automatically by integrating with an external API. It retrieves group membership data from a specified API endpoint and updates user-group relationships in ServiceNow accordingly. 
+
+This is useful for organizations where user groups are managed dynamically in external systems, and developer want a seamless and up-to-date integration with ServiceNow.
+
+# How It Works
+The script:
+- Fetches API Data: It connects to an external API (specified by the `apiEndpoint` variable) to retrieve the current group membership details.
+- Parses API Response: The response is parsed to extract user information (based on email) and group identifiers.
+- Updates Group Memberships:
+    - For each member in the response, the script queries the `sys_user` table to locate the user in ServiceNow based on their email address.
+    - Once a user is found, the script creates a new record in the `sys_user_grmember` table, associating the user with the appropriate group.
+
+# Implementation
+- Define the `apiEndpoint` URL, replacing `https://your-group-api.com/members` with the actual endpoint from which group membership data will be fetched.
+- Ensure that any necessary authentication for the API is configured, such as API keys or tokens.
+- This script uses email as a unique identifier for users. Adjust `userGR.addQuery('email', member.email)`; if another identifier is needed.
+- Deploy the script as a Business Rule in ServiceNow, setting the appropriate table and conditions under which it should execute. For example, it could run on a schedule or be triggered by a specific update.
