system replacemsg-custom-header

Use this command to include custom headers in block responses. This enables integration with downstream systems, improves observability, preserves user identity context, and aligns responses with enterprise security and application requirements.

These headers are included in the HTTP response and are intended for downstream clients and intermediary devices. They are not visible to end users in the rendered HTML content of the replacement message.

To use this command, your administrator account’s access control profile must have either w or rw permission to the sysgrp area. For details, see Permissions.
