Notion API: list all databases via search with an object filter, not the deprecated endpoint

Not specified by the original author.

TL;DR

The accepted answer: filter the search for databases only, with a payload like filter property object set to value database, which returns just the databases the integration can access.

Steps

1. When you need the list of databases a Notion integration can see, skip the deprecated /v1/databases endpoint. POST to /search with a filter of property object and value database. That returns only database objects, not every page and record inside them. Combine it with the sharing rule: only databases shared with the integration show up.
