# POST /sale/blacklisted-users stops working

Calls to POST /sale/blacklisted-users on Allegro REST API stopped working on April 30, 2024.

On April 30, 2024, the endpoint POST /sale/blacklisted-users stopped working. Calls made to this endpoint fail. Allegro removed the resources used to manage the inactive buyers list after previously marking them as deprecated.

## What to use instead

There is no API replacement because managing the inactive buyers list was taken out of the API. Manage the list directly in Sales Center instead.

Allegro took the inactive buyers list out of the API, with no replacement.
