Similar to the way you can [add `dependencies` to the *path operation decorators*](dependencies-in-path-operation-decorators.md), you can add them to the `FastAPI` application.

In that case, they will be applied to all the *path operations* in the application:

A default retention period and retention mode can be configured on a bucket to be applied to objects created in that bucket. Independent of retention, an object can also be under legal hold. This effectively disallows all deletes of an object under legal hold until the legal hold is removed by an API call.
