# Snowflake Database Plugin HTTP API
The Snowflake database plugin is one of the supported plugins for the database
secrets engine. This plugin generates database credentials dynamically based on
configured roles for the Snowflake database.
## Configure Connection
In addition to the parameters defined by the [Database
Backend](/api/secret/databases#configure-connection), this plugin
has a number of parameters to further configure a connection.
| Method | Path |
| :----- | :----------------------- |
| `POST` | `/database/config/:name` |
### Parameters
- `connection_url` `(string: <required>)` - Specifies the Snowflake DSN. This field
can be templated and supports passing the username and password
parameters in the following format {{field_name}}. A templated connection URL is
required when using root credential rotation.
- `max_open_connections` `(int: 4)` - Specifies the maximum number of open
connections to the database.
- `max_idle_connections` `(int: 0)` - Specifies the maximum number of idle
connections to the database. A zero uses the value of `max_open_connections`
and a negative value disables idle connections. If larger than
`max_open_connections` it will be reduced to be equal.
- `max_connection_lifetime` `(string: "0s")` - Specifies the maximum amount of
time a connection may be reused. If <= 0s connections are reused forever.
- `username` `(string: "")` - The root credential username used in the connection URL.
- `password` `(string: "")` - The root credential password used in the connection URL.
### Sample Payload
```json
{
"plugin_name": "snowflake-database-plugin",
"allowed_roles": "readonly",
"connection_url": "{{username}}:{{password}}@ecxxxx.west-us-1.azure/db_name",
"max_open_connections": 5,
"max_connection_lifetime": "5s",
"username": "username",
"password": "password"
}
```
### Sample Request
```shell-session
$ curl \
--header "X-Vault-Token: ..." \
--request POST \
--data @payload.json \
http://127.0.0.1:8200/v1/database/config/snowflake
```
## Statements
Statements are configured during role creation and are used by the plugin to
determine what is sent to the database on user creation, renewing, and
revocation. For more information on configuring roles see the [Role
API](/api/secret/databases#create-role) in the database secrets engine docs.
### Parameters
The following are the statements used by this plugin. If not mentioned in this
list the plugin does not support that statement type.
- `creation_statements` `(list: <required>)` Specifies the database
statements executed to create and configure a user. Must be a
semicolon-separated string, a base64-encoded semicolon-separated string, a
serialized JSON string array, or a base64-encoded serialized JSON string
array. The '{{name}}', '{{password}}' and '{{expiration}}' values will be
substituted. The generated password will be a random alphanumeric 20 character
string.
- `revocation_statements` `(list: [])` Specifies the database statements to
be executed to revoke a user. Must be a semicolon-separated string, a
base64-encoded semicolon-separated string, a serialized JSON string array, or
a base64-encoded serialized JSON string array. The '{{name}}' value will be
substituted. If not provided defaults to a generic drop user statement.
- `rollback_statements` `(list: [])` Specifies the database statements to be
executed rollback a create operation in the event of an error. Not every
plugin type will support this functionality. Must be a semicolon-separated
string, a base64-encoded semicolon-separated string, a serialized JSON string
array, or a base64-encoded serialized JSON string array. The '{{name}}' value
will be substituted.
- `renew_statements` `(list: [])` Specifies the database statements to be
executed to renew a user. Not every plugin type will support this
functionality. Must be a semicolon-separated string, a base64-encoded
semicolon-separated string, a serialized JSON string array, or a
base64-encoded serialized JSON string array. The '{{name}}' and
'{{expiration}}' values will be substituted.
- `rotation_statements` `(list: [])` Specifies the database statements to be
executed to rotate the password for a given username. Must be a
semicolon-separated string, a base64-encoded semicolon-separated string, a
serialized JSON string array, or a base64-encoded serialized JSON string
array. The '{{name}}' and '{{password}}' values will be substituted. The
generated password will be a random alphanumeric 20 character string.
