# Legacy summary

The documentation in this section is related to integration types and APIs
that are maintained for legacy reasons.

For new partner integrations, we **strongly recommend** using the most up
to date and appropriate [vertical documentation](https://developers.google.com/actions-center).

If your integration makes use of our legacy APIs, we suggest that you
reach out to your BD point of contact for assistance on how to upgrade to
the most recent versions of our API.
