# Mailchimp API 2.0 stops working

Calls to /2.0/* on Mailchimp Marketing API stopped working on June 1, 2023.

On June 1, 2023, Mailchimp retired API 2.0. Requests sent to the /2.0/* endpoints now fail and return an HTTP 410 status message. Calls made to these endpoints are no longer supported.

## What to use instead

Move the calls to the Marketing API 3.0 (/3.0/*).
