# 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](/docs/secrets/databases/index.html).

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.

## Configure Connection

This endpoint configures the connection string used to communicate with the
desired database. In addition to the parameters listed here, each Database
plugin has additional, database plugin specific,  parameters for this endpoint.
Please read the HTTP API for the plugin you'd wish to configure to see the full
list of additional parameters.

~> This endpoint distinguishes between `create` and `update` ACL capabilities.
