# Set group admins in bulk

> Call this API to batch assign or revoke admin roles for users in an enterprise group chat, ideal for large groups or organizational restructuring.

Call this API to assign multiple users in an organization's group chat as admins in bulk, or to revoke the admin role from multiple users in bulk. This API is suitable for scenarios where the organization's group chat is large and admins need to be adjusted in bulk to improve management efficiency, or when the organizational structure is adjusted and group admins need to be reassigned.

## Permissions

To call this API, one of the following permissions is required.
