The Taxonomy API creates, gets, updates, and deletes categories, event types, event properties, and user properties. You can edit planned events and properties, but not events and properties that already have data in the project.

For more detailed information about the Taxonomy API, refer to the [Taxonomy API](https://amplitude.com/docs/apis/analytics/taxonomy).
