# /apis/v4/projects/v0* is deprecated

Semrush API deprecated /apis/v4/projects/v0* without giving a shutdown date yet.

On July 2, 2026, Semrush API deprecated the /apis/v4/projects/v0* endpoints without a shutdown date. Affected methods remain operational temporarily, but calls to these endpoints will eventually fail. The change hits requests using the deprecated Projects API v4 methods.

## What to use instead

Call the Projects API v4 with API key authorization instead. This move requires creating a Version 4 API key rather than just updating an identifier.

The Projects API v4 takes a Version 4 API key, which has to be created.
