We are using a custom preference center and an automation that extracts contacts from our Master Permission DE, who have Opt-in set as 'false'. This DE that contains opt-outs is evaluated and later imported into All Subscribers list to unsubscribe them from further send-outs. Now, aside from using Automation Studio's SQL --> Data Extract > File Transfer --> Import Activity (into All Subscribers) flow, which has been buggy at best, is there a way to achieve this via Server-Side JavaScript? So, we would use SSJS in Automation Studio Script Activity on the DE where the opt-outs reside and have them unsubscribed from All Subscribers. Thanks


I did this before using SSJS the following way:

In your Script Activity using Marketing Cloud REST API endpoint to upsert values in the Data extension of your choice


To consume a REST endpoint in SSJS you can use Script.Util.HttpRequest to build and execute your request (explained in the documentation below)
