Database Secrets Engine (API)

This is the API documentation for the Vault Database secrets engine. For general information about the usage and operation of the database secrets engine, please see the Vault database secrets engine documentation.

This documentation assumes the database secrets engine is enabled at the /database path in Vault. Since it is possible to enable secrets engines at any location, please update your API calls accordingly.
