# Global Dependencies { #global-dependencies }

For some types of applications you might want to add dependencies to the whole application.

Similar to the way you can [add `dependencies` to the *path operation decorators*](dependencies-in-path-operation-decorators.md){.internal-link target=_blank}, you can add them to the `FastAPI` application.

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

        if (curlRequest == null) {
            final String msg = header;
            throwValidationError(messages -> messages.addErrorsInvalidHeaderForRequestFile(GLOBAL, msg), () -> asListHtml(this::saveToken));
