## Forbid Extra Query Parameters { #forbid-extra-query-parameters }

In some special use cases (probably not very common), you might want to **restrict** the query parameters that you want to receive.

You can use Pydantic's model configuration to `forbid` any `extra` fields:

#

#
# Maven system properties
#
# The properties defined in this file will be made available through
# system properties at the very beginning of Maven's boot process.
#

maven.installation.conf = ${maven.home}/conf
maven.user.conf         = ${user.home}/.m2
maven.project.conf      = ${session.rootDirectory}/.mvn

#

# Comma-separated list of files to include.
# Each item may be enclosed in quotes to gracefully include spaces. Items are trimmed before being loaded.

* Implement and use well-known cryptographic tools, like pwdlib and JWT tokens, etc.
* Add more granular permission controls with OAuth2 scopes where needed.
* ...etc.

Nevertheless, you might have a very specific use case where you really need to disable the API docs for some environment (e.g. for production) or depending on configurations from environment variables.
