# GET /list-batch-tests stops working

Calls to GET /list-batch-tests on Retell AI API stopped working on June 15, 2026.

The GET /list-batch-tests endpoint was shut down on June 15, 2026. Requests to this path fail since that date because the legacy endpoint is no longer supported.

## What to use instead

Call GET /v2/list-batch-tests and read the results from items, paging with pagination_key while has_more is true.
