# /v1/* is deprecated

Devin API deprecated /v1/* without giving a shutdown date yet.

Endpoints matching /v1/* on api.devin.ai are deprecated, and the provider has marked them for removal without a shutdown date. Once removed, requests sent to these routes fail. The deprecation affects all calls under the /v1/* path.

## What to use instead

Call API v3 under /v3/organizations/{org_id}/ for sessions, knowledge, playbooks, and secrets as mapped in the migration guide. Moving requires more than updating the route path, as API v3 authenticates with a service user and requires a new service-user key.

API v3 authenticates with a service user, so moving needs a new service-user key.
